LARRY FIELDS, FLIGHT STANDARDS SERVICE EXECUTIVE DIRECTOR
OF SOUND MIND AND BODY
When it comes to flying by instrument
flight rules (IFR), pilots need to learn,
practice, and understand a great deal to
operate safely in this visually restricted
environment. That includes everything
from expanding your aeronautical know-how, to executing the neces-
sary procedures and maneuvers with
precision, to being a subject matter
expert with the avionics to which you are entrusting your life. It’s a significant
step up from learning how to fly with a
real horizon always in sight. But there’s
one common, and sometimes over -
looked element in having what it takes
to be a successful and safe instrument
pilot — the human element.
Human factors loom large in the
world of instrument flying and it is something that needs to be both
acknowledged and thoroughly
reviewed to understand its impact.
And it’s not just human factors in the
physiological sense, but also in the behavioral sense. We can see the latter
more with how we’re able to effec-
tively interpret and understand tech-nology, maintain composure during
an emergency, and/or rationalize the
limits of our skills and abilities when external pressures are present.
Y ou’ll find human factors covered
extensively in many FAA resources,
including being front and center
in the Instrument Flying Handbook (Chapter 3). It’s also at the core of nine new FAA Safety Team online courses
that cover human performance, safety
culture, teamwork, and decision-mak-
ing, among several other areas. Go to
bit.ly/HFcourses to check it out.
This issue of FAA Safety Briefing
makes for another good resource to help better your understanding of IFR
flying and recognize its intersection with human factors. Y ou’ll find tips
and perspectives that can help you
not only navigate the Victor airways,
but also steer clear of the many aeronautical pitfalls an IFR environ-
ment presents.
For starters, IFR flying is a highly
perishable skill requiring a specific set of flight experience requirements to
act as pilot in command. But there are
myriad ways in which to practice and
gain that experience, including some you can employ from the comfort
of home. For more on this, proceed
direct to, “Into the Future. ” The article presents several good options to keep
your flying skills sharp and shows
how varying degrees of fidelity can
impact your choices toward gaining
and maintaining proficiency.
It’s well known that the accident
category that has traditionally had one of the highest fatality rates is VFR
flight into instrument meteorological
conditions (IMC). The article “Maybe Not Today” dives into many of the
reasons why this phenomenon con-
tinues to plague pilots of all skill levels and provides some sound strategies
to keep this killer at bay. It’s relevant
reading for pilots with or without an instrument rating.
Flying with no visual reference or
horizon can cause us humans to do
some odd things, many of which are
completely contradictory to basic safety if unprepared. For a closer look at spatial disorientation (an all-too-common term used in NTSB acci-
dent reports), see “It’s a Confusing
World Up There. ” The article pro-
vides a comprehensive overview of
“spatial D” and explains how the three-dimensional environment of
flight creates sensory conflicts and
illusions that make it difficult or even impossible to stay oriented. On that
same note, we also hear from the
FAA ’s Federal Air Surgeon, Dr. Susan
Northrup, on ways certain medi-
cations can sometimes exacerbate those disorienting conditions in the
Aeromedical Advisory department.
We hope the information within
these pages will help provide a pathway for being a more well-
rounded aviator with regard to IFR
flight. Remember — having an
instrument rating does not necessarily make you a competent all-weather
pilot. It is issued on the assumption
that you have the good judgment to
avoid situations beyond your capabili-
ties. Any instrument training that you undertake should help you learn the
essential physical flying skills, but just
as important is the ability to cultivate, maintain, and constantly refine the
proper mental skills that guide us to
safely conduct an IFR flight.
Safe Flying!
THERE’S ONE COMMON, AND
SOMETIMES OVERLOOKED ELEMENT IN HAVING WHAT IT TAKES TO BE A SUCCESSFUL AND
SAFE INSTRUMENT PILOT – THE
HUMAN ELEMENT.

AVIATION NEWS ROUNDUP
Updated Advisory Circular on
Engine Power-Loss Accidents
The FAA recently released AC
20-105C, Reciprocating Engine Power-
Loss Accident Prevention and Trend
Monitoring , which focuses on the
circumstances surrounding engine
power-loss accidents and recommen-
dations on how to prevent them. The
AC also provides charts and advice for
engine trend monitoring.
The updated AC highlights and
discusses several operational causes of engine failure, including inadequate preflight inspections, fuel contami-
nation and misfuelling, collapsed fuel
bladders, exceeding time between
overhauls, poor engine operating
technique, and maintenance mis-handling. Lack of pilot training and
mismanagement of the engine control
systems by the pilot remains the leading cause of engine failure.
Y ou can find this AC at

FAA Expands B4UFLY Services for
Drone Pilots
The FAA is now
partnering with several compa-nies to offer drone
pilots more places
to receive official
airspace awareness
information. The B4UFLY service shows recreational drone flyers where
they can and cannot fly.
The FAA has approved Airspace
Link, AutoPylot, Avision, and
UASidekick to provide services
through desktop and mobile appli-
cations. These companies will offer multiple ways to access B4UFLY and
provide recreational flyers with the latest airspace awareness information directly from the agency. For more
information, visit bit.ly/b4ufly.
Drone pilots can also find FAA-
approved partners who provide
near-real-time airspace authori-
zations and information at bit.ly/LAANCsuppliers.
Laser Strikes Increase to
Highest Numbers
Dangerous laser strikes topped all
previous records in 2023. The FAA
received 13,304 reports from pilots
last year, a 41% increase over 2022.
Shining a laser at an aircraft is a
serious safety threat. Many types of high-powered lasers can incapacitate
pilots, many of whom are flying air -
planes with hundreds of passengers.
Pilots have reported 313 injuries since
the FAA began recording data on laser
strikes in 2010.
People who shine lasers at aircraft
face FAA fines of up to $11,000 per violation and up to $30,800 for multi-
ple laser incidents. Violators can
also face criminal penalties from federal, state, and local law enforce-
ment agencies.
To identify laser-strike trends,
the FAA ’s visualization tool shows
laser-strike data from 2010 to 2023 and highlights trends by geographic
area, per capita data, and by time
of day and year. The FAA shares the information, at bit.ly/49HdgRl, to draw attention to the danger -
ously high rate. Laser report data by year can also be downloaded at bit.
ly/3Uaakb1.
The FAA strongly encourages the
public to report laser strikes to the FAA and local law enforcement agen-
cies at bit.ly/reportlaser .

FAA Accelerates ATC Hiring
by Enhancing College
Training Program
The FAA is working to accelerate
its training and hiring of air traffic
controllers through an Enhanced Air
Traffic-Collegiate Training Initiative
(AT-CTI) program. The Enhanced AT-CTI program will bolster the
current hiring pipeline by allowing
the FAA to hire more candidates who
can begin facility training immedi
ately upon graduation.
The FAA is authorizing institutions
in the AT-CTI program to provide the same thorough curriculum offered
at the FAA Air Traffic Controller Academy. After graduating from one
of the eligible schools, new hires can
immediately begin localized training at an air traffic facility. These grad-
uates must still pass the Air Traffic
Skills Assessment (ATSA) exam and
meet medical and security require-
ments. For more information, go to bit.ly/FAACTI.
The Enhanced AT-CTI program
is one of the many actions the FAA is taking to increase the number of
controllers and improve training
following the release of the National
Airspace System Safety Review Team
4 FAA Safety Briefing
ATIS GA news and current eventsReport. This includes year-round
hiring for experienced controllers
from the military and private industry,
filling every seat at the FAA Academy,
and finishing the deployment of
upgraded tower simulator systems in 95 facilities by December 2025.
New Pilot Minute Video Covers
BasicMed Requirements
Some pilots may wonder, if I’m on
BasicMed would I ever need to come
back through the FAA again? In a
recent episode of the Pilot Minute
video series, Federal Air Surgeon Dr.
Susan Northrup reviews the require-
ments for BasicMed and the mental
health, neurologic, or cardiac con-
ditions that would require a pilot by law, to be reexamined by an aviation
medical examiner (AME). See this

Latest GA Activity Survey Underway
The FAA ’s 46th annual
General Aviation and Part
135 Activity Survey (GA
Survey), reporting on the
calendar year 2023, is now
underway. The GA Survey
is the only source of infor -
mation on the GA fleet, the
number of hours flown,
and the ways people use GA aircraft.
Data from this survey
are used by governmental
agencies and industry to
compute safety metrics such as fatal accident rates; understand the impact of the GA industry on jobs,
economic output, and investments
in aviation infrastructure; track the
success of safety initiatives, including
avionics recommendations; determine funding for infrastructure and service
needs; and assess the impact of regu-
latory changes.
Selected participants will receive
an email or postcard invitation asking them to complete the survey online. A
mail survey is sent to those not com-
pleting online. The survey only takes 10-15 minutes to complete and your
responses are confidential.
The FAA and industry need accu-
rate data on a broad range of aircraft. Y our participation is voluntary, but
we need your help. We encourage
everyone who is contacted to respond
to the survey so that all aviation activity is represented. If you have
questions, call 800-826-1797 or email
infoaviationsurvey@tetratech.com.
Previous survey results can be

In response to the rapidly expanding
vertical aviation industry, Helicopter
Association International (HAI)
has changed its name to Vertical Aviation International (V AI). By
widening its focus to encompass all
vertical aviation, the association will
expand its advocacy with legislators
and regulators and provide a forum where all sectors of vertical flight can
collaborate on shared challenges, such
as vertical aviation infrastructure, certification of new technology, and
the safe integration of that technology
into the airspace.
The decision to rebrand stems from
the rapid expansion and technological evolution occurring in the vertical aviation industry. In addition to a new
logo, V AI has renamed its annual con-
ference and trade show VERTICON. The first edition of the show will be
held in Dallas in March 2025.
V AI is currently developing a new
website, verticalavi.org, which will
be launched in late summer 2024. In the meantime, visitors can go to
Rotor.org .
V AI is open to all manufacturers,
operators, suppliers, vendors, pilots, maintenance technicians, and aviation
professionals who serve or support
aircraft capable of vertical or short
takeoff and landing.

MISFORTUNE WITH MEDICATIONS
Given the IFR theme of this issue, I
thought it would be useful to review
several fatal accidents in which
spatial disorientation and/or med-
ication possibly contributed to the
outcome (special thanks to Dr. Loren Groff at the NTSB for his assistance)
and explain why we place restrictions
on some of these conditions/medica-tions. Here are a few examples listed
by the NTSB’s Case Analysis and
Reporting Online (CAROL) number
(carol.ntsb.gov).
CEN21LA089: A student pilot with
a passenger on board, took off into night, instrument conditions despite
having been advised that he could not carry passengers and was specif-
ically told not to fly that day due to
weather. At his Class III medical six
months earlier, he had not disclosed
his history of ADHD (attention deficit hyperactivity disorder) nor
the use of Vyvanse, an amphetamine.
The latter’s concentration greatly
exceeded the therapeutic level and
both it and the ADHD would have made him prone to impulsivity and
poor decision-making. Following 20
minutes of erratic flight after take-off, he entered a spiral descent that led to
a fatal crash.
CEN14GA135: The commercial
instrument pilot impacted the terrain
on a fire-spotting mission in marginal VFR conditions. The Cessna 210 was
instrument equipped but not main-
tained for instrument flight. There was no evidence that the pilot obtained a
weather briefing prior to flight. Three
weeks prior to the accident, the pilot
had started nortriptyline, an anti-de-
pressant also used for chronic pain, and tramadol, a synthetic opioid used
for pain control. Neither is authorized
for use when flying. While the pilot had disclosed the chronic knee pain, he began both medications after his
last FAA medical examination.
ERA17FA180: The non-instrument
rated private pilot and his passenger
were in a fatal crash following con-tinued flight into IMC conditions
and probable spatial disorientation.
While the pilot did have over 80 hours of instrument experience, he had no
instrument time logged in the past
year and was not instrument rated.
The pilot had not disclosed the use of
imipramine, an anti-depressant not authorized for use by the FAA due to
cognitive impairment and sedation, as
well as doxylamine, a sedating antihis-tamine with a 60-hour no-fly period
following use.
CEN14FA042: A flight instructor
and private pilot impacted rising
terrain while on an instrument
approach during a combined business
trip and instrument training flight. The mishap was at night in instru-
ment conditions at the end of a long
day which began approximately 13 hours earlier and after almost 6 hours
of flying over three legs. Toxicological
testing showed the presence of dextro-
methorphan in the blood of the flight
instructor and diphenhydramine at therapeutic levels in the blood of the
private pilot receiving instruction.
Both medications cause cognitive impairment and drowsiness. The FAA period for the residual concentration to be clinically insignificant is 48 and
60 hours, respectively. It could not be
determined who was the pilot flying at the time of impact.
Looking at these accidents, it
is clear that experience does not
prevent spatial disorientation or con-
trolled flight into terrain accidents. Pilots ranging from students to
instructors, sport pilots to commer -
cial pilots are represented. What is
clear is that some medical conditions
and many medications can impair
both judgement and the ability to
control an aircraft. There are reasons
that these are considered incompati-ble with flying and disqualifying for
an FAA medical. Flying either as a
sport pilot or under BasicMed offers
no protection from the impairment
from these different conditions and medications. Of the total accidents
between fiscal years 2019 and 2023,
the percent positive for psychotropic medications (affecting the mind) rose
from approximately 8.5% to approx-
imately 13%. These medications
include antidepressants, antipsychot-
ics, anxiolytics, and stimulants with antidepressants the most common.
Please note that this does not reflect
accidents related to other conditions
or medications. Remember, some-
times the best decision is not to go;
you may save your life.WHAT IS CLEAR IS THAT SOME
MEDICAL CONDITIONS AND MANY MEDICATIONS CAN IMPAIR BOTH JUDGEMENT
AND THE ABILITY TO CONTROL AN AIRCRAFT.
It’s a Confusing World
Up There
The Specifics of Spatial Disorientation
By Nicole Hartman and Rebekah Waters
It’s sobering to search the National Transportation Safety
Board (NTSB) database for accidents caused by spatial
disorientation, or “spatial D. ” The query produces
page after page of accidents — hundreds of aviators have succumbed to this confusing condition. Statistics show
that between 5 to 10% of all general aviation accidents are attributed to spatial disorientation, and 90% of those are
fatal. NTSB data suggests that spatial D is a more common
occurrence at night or in limited visibility weather condi-tions. All pilots are susceptible to the optical illusions that
may cause loss of aircraft control at any time. Let’s take a
closer look at the causes of spatial disorientation, review
the types, and discuss strategies for preventing this source
of aviation accidents.
Seeing Isn’t Always Believing
Spatial orientation is our natural ability to maintain our body’s orientation and/or posture in relation to the sur -
rounding environment (physical space) at rest and during motion. The three-dimensional environment of flight is unfamiliar to our bodies and creates sensory conflicts and
illusions that make spatial orientation difficult. The numer -
ous sensory stimuli (visual, vestibular, and proprioceptive) during flight vary in magnitude, direction, and frequency
and can lead to sensory mismatches resulting in disorien-tation. This condition is known as spatial disorientation
— the inability of a pilot to correctly interpret aircraft atti-
tude, altitude, or airspeed in relation to the Earth or other points of reference.
Becoming spatially disoriented is the result of a prop-
erly functioning human system, which we are hard-wired
to trust, misinterpreting our actual position or orientation
in space. It goes against our natural instincts to accept that our orientation isn’t what it appears to be. Even a
brief loss of orientation while in flight for 10-15 seconds
can result in an unusual aircraft attitude putting the pilot
and passengers at risk for an accident. The sensory inputs
needed to maintain orientation automatically and subcon -
sciously used to orient ourselves include visual, vestibular,
and proprioceptive.
6 FAA Safety Briefing
May/June 2024 7Visual Vestibular ProprioceptiveThe human eye is responsible
for 80% of the sensory inputs
needed to maintain orientationReceptors in the skin, muscle, tendons, and joints account for
5%The system within the inner ear contributes
15%
The visual system includes the eye and its
component parts that are necessary for visual
acuity (focus), depth perception, and assessing
the body's position in space relative to other objects both fixed and moving. During flight, visual reference is the
largest contributor to accurate spatial orientation. By using visual references, the pilot can gather information about
distance, speed, and depth. Any condition that deprives
the pilot of natural visual references, such as clouds, fog, haze, darkness, terrain, or sky backgrounds with indistinct
contrast (i.e., arctic whiteout or clear, moonless skies over
water) can rapidly cause spatial D.
The vestibular system includes the sensory
organs contained within the inner ear that detect relative motion of the head in space within its
axes of movement. It consists of two major components: the semicircular canals that detect changes in rotational acceleration, and the otolith organs that detect linear
(straight) acceleration. Y our vestibular system’s primary
function is to detect rotational and translational move-
ments of the head and generate a corresponding response
signal. But this system was designed to function on the ground in a 1G environment (normal gravity). Accidents
can occur due to a combination of vestibular illusions and
poor visibility. When the body is subjected to certain forces
that cause a vestibular illusion, vision is often the only
sense that can contradict these false perceptions. However, in darkness or other poor visibility conditions, it is much
easier to be deceived by an illusion and to ignore informa-
tion provided by your instruments.
Proprioception is a term that encompasses
the human sensation of the body's (trunk/limbs) position as it relates to space and forms the foun-
dation about which the other sensory organs guide desired movements within that space. Proprioceptive sensory inputs give us a reference to posture and the relative posi-
tion of our body in relation to our environment.Prone to Puzzlement?
It is important to recognize that even when a pilot's visual,
vestibular, and proprioceptive systems are working prop-
erly, associated underlying medical conditions or human
factors can increase the risk for spatial D. There are both
external and internal factors that will increase a pilot’s
susceptibility to spatial disorientation. Any visual condi-tion that reduces a pilot’s ability to maintain orientation to
the horizon (i.e., clouds, haze, night conditions, terrain)
will increase the risk of spatial D. Additionally, a pilot may be more vulnerable to spatial disorientation as a result of
age, fatigue, stress, anxiety, or get-there-itis. Some medical
conditions, medications, smoking, alcohol, and other drugs
that affect the visual, vestibular, or proprioceptive sensory
inputs can also increase susceptibility. Be sure to read the Aeromedical Advisory in this issue for examples of how
certain medications can exacerbate spatial D.
Don’t Trust Your Gut
Without visual references (e.g., VFR at night/low visibility
and IFR flying), pilots can become disoriented, especially
in situations like low visibility or turbulent weather, where
sensory inputs can be conflicting or misleading. When
visual cues are absent, your body will turn to your ves-
tibular system for information. The vestibular system is complex and can be easily deceived in certain flight con-
ditions. When motion makes this system unreliable, pilots
experience vestibular illusions. These dangerous illusions are the most likely culprits of spatial disorientation.
There are six types of vestibular illusions you may
encounter while flying IFR. The most common illusion,
“the leans, ” occurs after a sudden return to level flight after
a gradual and prolonged turn. If the rotational acceleration of the turn is 2 degrees per second or lower, your vestibular
system will not detect this movement. When you level out
after a turn like this, you may experience the illusion that your aircraft is banking in the opposite direction. If you
rely on what your body is telling you, you might lean in the
direction of the original turn to regain what you think is
the correct vertical posture. The brain combines sensory signals (left) in order to maintain control of the body.

8 FAA Safety BriefingIf a pilot is in a
turn long enough
for the fluid in the
ear canal to move
at the same speed
as the canal, the “Coriolis illusion” can
occur — the most
dangerous vestibular illusion. A sudden head movement,
such as looking down at something you dropped during a
prolonged turn can give you the false sensation of rotation
or acceleration on an entirely different axis. When disori-
ented by this illusion, you might maneuver the aircraft into
a dangerous attitude while trying to correct your aircraft’s perceived attitude. This is why it’s so important to practice
moving your head as little as possible during instrument
cross-checks or scans. Make sure you keep your head as still as possible when reaching for charts and other objects
on the flight deck.
A prolonged coordinated constant-rate turn could cause
the sensation of flying straight and level. This is when you
are in danger of experiencing the “graveyard spiral. ” Aircraft tend to lose altitude in turns unless you compensate for
the loss in lift. When making a con-
stant-rate turn, you
may notice a loss of altitude, even though
you aren’t experienc-
ing the sensation of turning. This creates
the illusion of being
in a level descent.
Y our gut might tell
you to pull back on
the controls in an attempt to climb or stop the descent. If
you listen to your gut instead of trusting your instruments,
the spiral will tighten and increase the loss of altitude. This could lead to a loss of aircraft control.
The “somatogravic illusion” occurs during rapid accel-
eration and creates the same feeling as tilting your head
backward. Pilots experiencing this feeling can mistake it
for a climb, especially while flying IFR. This disorientation could make you want to push the aircraft into a nose-low
or dive attitude. A rapid deceleration could make you feel
the opposite sensation and urge you to pull up, putting you
in danger of a nose-up or stall attitude.
When you make a sudden return to straight and level
flight after a climb, it can feel like you are tumbling backward. This is known as “inversion illusion. ” The
disorientation you feel from this might lead you to push your aircraft abruptly into a nose-low attitude, which can
intensify the illusion.Like the “inversion
illusion, ” the “eleva-tor illusion” is also
caused by an abrupt
change. A sudden
upward vertical accel-eration, as can occur
in an updraft, can
stimulate your otolith organs and create
the illusion of being in a climb. This could make you want to push the aircraft into a nose-low attitude. An abrupt
downward vertical acceleration, usually in a downdraft, has
the opposite effect making you want to pull the aircraft into a nose-up attitude.
Do Your Eyes Deceive You?
Spatial disorientation can also be caused by visual illusions. Y our mind believes what it sees, which can be dangerous for
pilots. “False horizon” occurs when your mind uses inac-
curate visual information, like a sloping cloud formation,
when trying to align your aircraft with the actual horizon.
This type of illusion can be disorienting and lead you to place your aircraft in a dangerous attitude. “ Autokinesis” is
another visual illusion that can happen when flying at night.
If you are attempting to align your aircraft with a stationary light, autokinesis could create the illusion that the light is
moving. When this happens, you become disoriented and
could potentially lose control of your aircraft.
Combating Spatial D
Reviewing the NTSB data reveals that there are many causes of spatial disorientation, but the outcome for the
majority of the accidents is the same — fatality. So, what
can you do to avoid these dangerous situations? “Preflight
weather planning is critical to avoiding an inadvertent
encounter with instrument conditions, ” said Katherine Wilson, senior human performance NTSB senior human
performance investigator. “But if a pilot finds themself in
that situation, it is important they trust their instruments and exit the conditions as quickly and safely as possible. ”
Y our first line of defense against spatial D should be
practice, practice, and more practice. Undergo regular
training on spatial disorientation recognition and recovery
techniques so you will be aware and prepared for potentially disorienting situations. Consider experiencing spatial D
firsthand, either with a flight instructor or in a simulator.
It goes against our natural instincts
to accept that our orientation isn’t
what it appears to be.
May/June 2024 9Y ou could also immerse yourself in the visual and vestibular
illusions that you might encounter at a spatial disorienta-
tion laboratory. Many universities and the military use labs
to simulate various flight conditions and scenarios to train
pilots to recognize and cope with spatial D. Experience
the disorientation in a controlled environment, and prac-tice overcoming what your body is telling you so you can
commit to trusting your instruments. To learn about train-
ing offered by the FAA go to bit.ly/FAACAMIED .
Set yourself up for success — to help prevent spatial
disorientation, pilots should:
• Obtain training and maintain proficiency with flying instruments before flying with less than three
miles visibility.
• Use and rely on your flight instruments, especially at
night, in reduced visibility, and in featureless and sloping
terrain. Be sure to test your flight instruments before
each flight as well as during your preflight and taxi.
• Maintain night currency if you intend to fly at night. Include cross-country and local operations at differ -
ent airports.
• Do not attempt VFR flight when there is the possibility of getting trapped in deteriorating weather.
• If you are flying with another pilot and start to experi-ence spatial D, transfer control. Pilots rarely experience
visual illusions simultaneously.
• Plan your transition to instrument flying before you
enter IMC. Start your instrument scan while you are
still in visual conditions.
• Avoid movements in the cockpit that are prone to
cause spatial disorientation when flying by reference to
instruments. Sudden head movements, or the classic
“reaching down to pick up a dropped pencil” may
bring on sudden disorientation.In addition to these tried-and-true methods of combat-
ing spatial D, it is also important to:
• Study and become familiar with unique geographical
conditions in areas where you plan to operate.
• Check weather forecasts before departure, enroute, and at your destination. Be alert for weather deterioration.
• Consider practicing maneuvers that illicit illusions with your flight instructor to maintain proficiency.
• Contact your FSDO for opportunities to use a full motion simulator and experience the illusions you
might encounter.
• Set personal minimums for VFR and IFR flight
designed to minimize your exposure to conditions that
increase your risks.
Remember, once you enter instrument conditions,
completely commit to instrument flying. Attempting quick
transitions to visual flight because you spotted a hole in
the clouds or caught a glimpse of the ground below may
cause spatial disorientation that could have been avoided by maintaining a proper instrument scan. Although it's
tempting to reengage in visual flight when going in and out
of clouds, keep the instrument scan and don’t transition back to visual flying until you have the necessary visibility
and visual references to do so safely. Resist this temptation,
and follow the strategies mentioned above to make sure
you have a safe and successful flight no matter what flying
conditions you encounter!

INTO THE FUTURE
How Leveraging Technology
Can Help Build Proficiency
in a Busy World
By James Williams
The most indispensable resource of this, or any age,
isn’t money. It’s time. Time can be used to gener -
ate money, build experience, enjoy yourself, or any
number of other things. But time is finite and flows in
only one direction, at least until Doc Brown can get the
flux capacitor working and the Delorian up to 88 miles per hour. Concurrent with the passage of time, we have
the natural trend that erodes the skills we work hard to
attain/create. But what does any of this have to do with IFR (instrument flight rules) flying and how does tech-
nology play a role in keeping pilots' skills sharp?
The Triangle of Proficiency
With instrument training, there is a tendency to some-
times conflate currency with proficiency. Currency is easily
defined (see Title 14, Code of Federal Regulations (14
CFR), section 61.57 (c)). Proficiency is more challenging
to delineate. While proficiency is defined in the Airman
Certification Standards and Practical Test Standards testing documents, on an individual day-to-day basis, it is based
more on an individual's assessment. It’s similar to art in
that it’s subjective and based on an individual’s appraisal. There is a test for both proficiency and art. In art, a piece is worth what someone will pay for it. Proficiency is safely
completing your flight in the conditions as they exist.
Y our flying skills, particularly instrument skills,
decay if they are unused, and the essential resource to
prevent that degradation is time spent exercising those skills. While money is certainly a consideration, time is Modern Electronic Flight Bag (EFB) software allows you to practice skills like flight planning
and briefing anywhere and anytime.

May/June 2024 11genuinely the most constrained resource. With limited
resources to address a problem, the first step is to state
your objective. How do we define proficiency in a mean-
ingful way we can use?
Our former editor, Susan Parson, covered this topic in
2010 with her concept of the “Proficiency Triangle. ” The three sides of this triangle are Planning , Performance , and
Procedures . These components are core facets of profi-
ciency and give us areas to focus on and exercise. While we tend to think of proficiency in terms of the latter two
aspects (performance and procedures), planning is prob-
ably more important. Planning is critical, as it can prevent
you from having to test the other two components in a way
that you may not be able to pass. We also don’t think of planning as a perishable skill we can practice, but it is. In
fact, it can be practiced easily and from anywhere.
Performance is a prominent component. If you can’t
control the aircraft, it’s all moot. But aircraft control is best thought of as being on a sliding scale. How does
your ability to control an airplane in clear blue smooth
skies compare to that in a large turbulent cloud? Even for
proficient pilots, there are bound to be differences. And that leads into the final facet of the triangle, procedures.
Being unfamiliar with a process or procedure means that
you likely to need to focus more of your attention on that
process. That means less attention on things like aircraft
control. We have a limited amount of what physiologists call attentional resources, so the more of that resource that
goes into the process's basic function, the less that can be
allocated to aircraft monitoring and control (and that’s without going down the rabbit hole around multitasking
and whether humans can do it in a remotely effective
way). But to be sure, having experience and proficiency
with procedures allows you more attention for other tasks.
Improving any of these facets is good, but maintaining pro-ficiency in all three is the best way to maximize your safety.
So, how do we accomplish this?
A Mixed Approach
The best way to stay proficient is to fly several times a
week, if not daily. But this presents a significant chal-
lenge for most of us who aren’t professional pilots or have
more disposable income. In addition, training conditions
(smooth low clouds without the threat of thunderstorms or icing) to truly hone instrument skills can be challeng-
ing to find, even if you don’t have obstacles like full-time employment to worry about. This is where fidelity becomes
essential. We can practice flight planning and go/no-go
decision-making relatively easily. With modern flight brief-
ing and planning suites, it’s simple to have a few canned
flight plans you can brief, review, and decide on in a few minutes, even if you don’t intend to fly.
Where we need to get more creative is with performance
and procedures. Obviously, practice approaches and pro-cedures in the real world are the best in many ways, but we have limitations. We can’t control the weather and using
view-limiting devices doesn’t quite capture the real expe-
rience. But whether we are trying to practice performance or procedures does change our approach to some extent.
Focusing on procedures could start with a computer or
tablet. Garmin offers software that will let your machine
“run” simulated Garmin avionics to allow you to manipu-
late the systems virtually and learn how to operate them. While this is a lower fidelity approach, it is an excellent tool
for learning how these systems function so that you already
have a base knowledge level as we add stress factors. From there, aviation training devices (ATD) will add actual
hardware switches, buttons, and knobs that replicate the
real cockpit systems. This is a nice validation step, but
ATDs aren’t always available as that high-quality hardware
and validation increases the cost of acquisition out of reach for many people. But you can always use a computer and
commercial flight simulator software to get many benefits
in your home.
The Virtual Super Skyway
I’ve been a long-time proponent of using simulation for proficiency and training. I used a computer with an old-
school monitor and X-Plane 6 to pre-fly my cross-country
flights in my dorm room the day before training. Even
with the much lower-quality visuals of the late 1990s to
early 2000s, it was a great way to see the route before a flight. Since 2020, the flight simulator space has enjoyed a
renaissance with the return of Microsoft Flight Simulator
2020 (FS2020) after more than a decade out of the market. Microsoft is planning a follow-up Flight Simulator 2024 to
be released later this year with various improvements over
the current program. This means we have two high-quality Y our flying skills, particularly
instrument skills, decay if they are
unused, and the essential resource
to prevent that degradation is time
spent exercising those skills.

commercially available flight simulators that can drive
innovation. See "Fly into the Matrix" (bit.ly/FlyInVR) from
our Jan/Feb 2021 issue for a deeper dive into personal
computer simulation. The bottom line is that FS2020 and
X-Plane are great programs that can be useful. I prefer
X-Plane for a couple of reasons, including slightly better physics/airplane handling and easier flight setup. FS2020
has a better visual presentation, especially if you have a
higher-end graphics processing unit (GPU), but it isn’t quite as well set up to “do work” in terms of ease of set up
for specific tasks. These are relatively small differences
overall, and the situation hasn’t changed much since late
2020, when I wrote the other article.
Both programs are available on a trial/demo basis for
free or very low cost. X-Plane, as a downloadable demo, is a great way to ensure it will run well on your system
before investing in a full copy. FS2020 is available as part of Microsoft’s monthly subscription, Game Pass. A PC-only
Game Pass subscription is a relatively cheap way to test
FS2020. Even at lower visual settings, both programs are
a great way to hone your skills in weather that would be
dangerous to try in real life without support. This lets you practice both the flight performance and procedures you
want to brush up on.
To add even more realism, there are services like
PilotEdge and V ATSIM (Virtual Air Traffic Simulation
Network) that provide virtual air traffic services so you can practice procedures with ATC, in some cases guided by
actual air traffic controllers. This kind of extension of com-
puter-based flight sims allows for very realistic IFR oper -
ations and practice. Especially on a weak point for many
pilots, radio communications. Getting virtual radio reps
can make you more comfortable and means you have more
attention to focus on other tasks. The addition of air traffic
services is a significant advancement since I was learning to fly and allows you to practice IFR operations in a much
more realistic fashion than having your instructor provide
canned instructions.
To VR or not to VR …
That is the question. There are additional costs, both financial and time, that virtual reality (VR) imposes
versus a traditional monitor-based PC system. Y ou will
need more powerful and expensive components and will
also have to spend time getting everything properly set
up. However, VR technology, once properly qualified, could help bring down the cost of flight training and
make routine training more attainable.
The advantage VR provides is best summed up in one
word — immersion. It does make you feel much more connected to the experience. For practicing the perfor -
mance aspect, immersion can help. I still remember when that fact really hit me. I was practicing a touch-and-go, and my final approach got a bit unstable. I could “feel” it
in a very similar way to what I would in a real airplane.
That connection makes the experience a much higher
fidelity one. Regarding practicing aircraft control, the
higher the fidelity, the better. Unlike process and proce-
dure practice, where reducing fidelity can be valuable, aircraft control is a different beast. Especially in a con-
sequence-free virtual environment, you want the most
realistic conditions.
Building Your Own Triangle
We’ve discussed dissecting proficiency into planning, performance, and procedures. From there, we looked
at ways to hone each of those facets. I would propose a
second triangle, a fidelity triangle. The fidelity triangle
consists of high, medium, and low-fidelity approaches. It’s
not necessarily equilateral, but varies based on available time and conditions. High-fidelity training, i.e., flying the
airplane, will likely be the short leg in this shape. Lining up
the conditions, an instructor, and disposable income can be challenging. It’s also a good block of time. The minimum
time commitment for a flight would be 2-3 hours total
for an hour in the air. This isn’t to say you shouldn’t take
advantage of the opportunity; it's just that the chances will
be limited in our busy lives.
The medium-fidelity training would be ATD or com-
puter simulation. There’s a spectrum in quality from a high-end ATD, to a VR setup, to a basic computer. While it’s not the real thing, it offers better availability and

controllable conditions. When possible, try to work in
periodic sessions in an ATD as a good check-up. It can
be a cost-effective way to ensure you are on a good path
regarding your proficiency. ATDs may also allow you to
log the time and experience under certain circumstances.
Y ou can use your home-based system to brush up on any deficiencies the ATD sessions uncover. If you're working
from home, you can also pop in and do a quick approach
or any other procedure that’s giving you trouble before your next check-up.
Low-fidelity training can still serve a purpose. This
would include things like practice briefings and planning.
Although I would argue that the task's fidelity is high as
it’s functionally the same regardless of intent to fly, from an effort and ease of operation standpoint, it is much more
accessible than the above-listed tasks. Y ou can even do it in
a waiting room before an appointment or meeting. Other
low-fidelity tasks include working with training software
to dig into your avionics suite or reading manuals or safety publications like this one. Keeping your mind engaged in aviation is an excellent way to keep proficiency a priority. It
also can inform your priorities for higher fidelity training.
Did you see conditions in a briefing or accident report and
wonder how you might deal with them? Why not give it a
try in the virtual environment of an ATD or PC sim? That experience can then feed back into your personal mini-
mums and future flight planning.
How you balance that triangle in pursuit of a well-honed
proficiency triangle will depend on your circumstances. Over time, you can refine your triangle and balance your
fidelity needs to stay proficient. This will change over time
and will require rebalancing. The wide variety of technol-
ogy available to us today gives us many daily opportunities to work towards greater proficiency. But once you have a
base, you can work from there and find the right mix to
keep you safe and proficient in the future.

Avoiding the Perils (and Regrets) of VFR into IMC
By Sabrina Woods
(Editor’s Note: This article originally appeared in the Jul/
Aug 2018 issue of FAA Safety Briefing and was updated
for this issue.)
In 2009, a non-instrument-rated pilot originally
planned for a much-anticipated cross-country trip,
but instrument meteorological conditions (IMC)
conditions at the airport prevented the pilot from leaving
on the intended day. After two days of waiting, IMC
still prevailed; however, several witnesses observed the
pilot and the pilot’s son at the fuel dock. They all assumed that the pilot would taxi back to the hangar since the
ceilings were between 200-400 feet above ground level
(AGL). Instead, the airplane departed and disappeared
into the overcast clouds. Multiple witnesses heard the
airplane continuously change speed and direction, fol-lowed by the sound of the airplane impacting the ground.
Airplane components were found in two locations —
at the main wreckage site and along a debris path that consisted of the outboard portions of the left wing and
left stabilator. Both the pilot and son suffered fatal inju-ries in the crash.
May/June 2024 15
In 2019, a non-instrument-rated commercial pilot
encountered fog shortly after departing for a visual flight
rules (VFR) aerial application flight in an aircraft not
equipped for instrument flight rules (IFR). The pilot
attempted to fly above the fog layer and divert to a local
airport. However, aircraft tracking data shows the airplane entered two spiraling turns, the second of which involved
a rapid descent in the direction of the fatal accident site.
Investigators determined this to be consistent with the effects of spatial disorientation in IMC conditions. They
also were not able to determine if the pilot received an
official weather briefing before the flight.
In 2021, a non-instrument-rated pilot departed in a
helicopter shortly after sunset in visual meteorological conditions (VMC). About an hour into the fight, the pilot
encountered snow showers and IMC conditions that were
forecast to move through the route of flight. Radar data showed that after entering the area of weather, the pilot
began a right descending turn and the helicopter crashed
in a rural, wooded area. Investigators believed that operat-
ing in a helicopter not approved for IFR flight and with no
instrument rating, in addition to the overcast skies, snow showers, and a lack of terrestrial illumination in a remote
area, were conducive to spatial disorientation and subse-
quent loss of control in this unfortunate fatality. There was
also no evidence the pilot reviewed the weather or received
a briefing before the flight.
Shocked!
Each year, the Richard G. McSpadden Report (formerly the Joseph T. Nall Report) provides a detailed analysis of
general aviation (GA) accident data and safety trends. A
look at the most recent finalized data from the report in
2021 indicates there were 938 non-commercial, fixed-wing
accidents, with an overall lethality rate of 17.7%. More than 80% of the accidents that occurred in IMC were fatal,
compared to 15% of those that occurred within VMC. As
the preceding accident summaries demonstrate, flying VFR into IMC is still one of the most lethal causal factors for
GA mishaps. For this reason, the National Transportation
Safety Board (NTSB) has determined it to be a significant
safety hazard for the GA community.
What stands out is that, unlike most of the other
mishap causal factors, this particular rate of occurrence has remained stubbornly fixed — drifting between a 79
to 92% fatal accident rate for VFR into IMC over the last several decades. Decades ! This is despite several significant
upgrades in weather forecasting technology and a continued safety awareness effort focused on this subject. My research
left me shocked and more than just a little concerned about
why this particular phenomenon keeps occurring.
So Why Does It Still Happen?
The FAA, NTSB, and various aviation safety advocates from industry and academia alike have tried to determine
what happens when a pilot finds themselves in the incred-
ibly hazardous situation of being VFR and then flying into
IMC conditions. Some researchers have theorized that
cockpit technologies are insufficient at depicting meteoro-logical conditions in real-time. Others believe that pilots
get distracted or overestimate their aeronautical abilities.
Others even go so far as to accuse aviators of being willful in disregarding the dangers and deem flying VFR into
IMC as negligence.
While I think some of these ideas have merit (others,
not so much), I, too, have a couple of different theories to
offer on how VFR into IMC can happen. I humbly present to you what I call the “just around the river bend” bad idea;
the “where’ d everybody go?” gaffe; and the “there’s no place
like home” hot spot. Let me explain further ….
It’s Just Around the River Bend … ?
In this situation, a pilot is flying along when the visibility starts to deteriorate. Instead of diverting from the unde-
sirable condition or even just landing the aircraft, the pilot
continues, thinking that clearer conditions might be just
“around the river bend. ” Or worse, they rely on the latest
weather app to “shoot the gap” and try to fly through the inclement weather.
Flying VFR into IMC is still one of the
most lethal causal factor for
GA mishaps.
Others even go so far as to
accuse aviators of being willful in
disregarding the dangers and deem
flying VFR into IMC as negligence.

16 FAA Safety Briefing
As you might notice in a previous article I wrote,
“Weather … Or Not? Weather Technology in the Cockpit”
(adobe.ly/3VmDMf0), I discussed the FAA ’s Weather
Technology in the Cockpit (WTIC) program to educate
pilots on the inherent inaccuracies, latencies, and limita-
tions of weather displays in the cockpit. Information that you see on your favorite weather app might not be real-
time, with lagging delays of up to 20 minutes! This means
that the hole a pilot might try to slip through is no longer there upon arrival.
Another reason some pilots are reluctant to turn around
is what human factors scientists call “sunk cost bias. ” In
general, we are often reluctant to turn away from something
when we feel we have already put a certain amount of time, effort, and money into it. We would rather hang on just a
little longer because we value the very real “wasted” effort
more than the intangible hazard. Regardless, waiting for a hole that might never manifest, prioritizing the extra money
you burned, or trying to get to your destination is just a bad
idea when dealing with foul weather or poor visibility.
Where’d Everybody Go?!
Another reason pilots might unwittingly find themselves in a bad “VFR into IMC situation” is because the conditions
change without the pilot observing it happening. Picture
this: Y ou are flying along in VFR conditions when you take
a moment to fiddle with your radio that keeps emitting a
high-pitched squeal when you key the mic. Once satisfied that the squelchy situation is resolved, you look up to find
yourself on the cusp between marginal VFR conditions and
IMC. The soup is getting worse with every passing minute, and the “where’ d everybody go?!” panic starts to set in.
This scenario is more common than you might think
and is often the result of distraction — when something
not pertinent to the task at hand captures and holds your
attention; or fixation — when you are overly focused on one specific task to the detriment of all others. Poor
situational awareness, lack of experience in interpreting
changing weather conditions, and overestimating one’s own abilities are also common culprits in missing the shift from VMC to “not-VMC. ” These mistakes can break down
the efficacy of your aeronautical decision-making making,
which can lead to additional errors and an increase in risk. Mitigate them by creating systematic procedures that work
for you and your aircraft type, and by creating and closely
following a scan pattern.
There’s No Place Like Home
Very similar to the “just around the river bend” bad idea is the overwhelming desire to just get home. Colloquially
this is called “get-home-itis" or “get-there-itis”; however,
most theorists refer to it as plan continuation bias. It is
like the former because the aversion to sunk costs is the
same. But get-home-itis often goes much deeper because the pilot is particularly keen to accomplish their goal even
though things have changed and there are indications that
doing so is very risky (see the Air Safety Institute video in Learn More). Sometimes complacency — I’ve done it
before, so why shouldn’t it work this time? — over-reli -
ance on technology, and good ol’ fashioned pride can get in the way of a person’s making the safer, albeit seemingly
inconvenient choice.
Victims of plan continuation bias can be internally
motivated (e.g., wanting to get home to a waiting family member), externally motivated (e.g., wanting to get the rental back to avoid additional charges), or a combination
of both. When it comes to flying VFR into IMC, this bias
can compel a pilot to make unsafe choices in their aeronau-
tical decision-making. An excellent and rather sad example
is in the very first paragraph of this article. Even though we all know there is no place like home, sometimes it is better
if the getting-there desire waits in deference to a safer
course of action.
An Ounce of Prevention …
Benjamin Franklin once penned that “an ounce of preven-tion is worth a pound of cure. ” Granted, Mr. Franklin was
talking about fire safety; however, the axiom rings true
today and is easily applicable to a host of different situa -
tions. Thorough pre-flight planning and being conscious of your skill set and experience level aids in thwarting VFR into IMC tragedies. The best time to take preventa -
tive measures is by building a solid “Plan A ” and a “Plan B” before you go fly. If you are anything like me, you will even build a “Plan B++. ” In your plans, you should consider Even though we all know there is
no place like home, sometimes it
is better if the getting-there desire
waits in deference to a safer course
of action.
what alternate courses of action will be available if the
weather or visibility starts to turn sour, when you should
consider adopting those courses of action, and a realistic
assessment of your own personal minimums so that you
know exactly what you need to do to avoid ever getting
close to a bad situation.
Trust me on this. Being in the thick of things is no time
to try and reconnoiter and develop a Plan B. Spatial dis-orientation, in particular, often goes hand-in-hand in VFR into IMC accidents. When it comes to deteriorating weather
conditions, if you are not instrument-qualified, the best
course of action is to remain in VFR conditions and land
the plane as soon as possible.To put a different twist on an oft-quoted line from the
famous final airplane scene in Casablanca: If that plane
leaves [VMC], you'll regret it — soon and for the rest of your life. Because if you do the right thing, then maybe not
today, and maybe not tomorrow, you will eventually get
where you’re going, but without the regrets that you — or the loved ones you leave behind — would have if you fall
prey to a VFR-into-IMC accident.

Understanding and Navigating
Glass Avionics Failures
By William E. Dubois
Instead of “break glass in case of emergency, ” in the
modern flight deck, “broken glass” is an emergency in
and of itself — a first-rate emergency that can spiral out
of control with mind-numbing speed. Sure, modern glass avionics are the gold standard for reliability — much more
reliable, on average, than their analog pneumatic- and elec-tric-gyro predecessors. That said, anything that humankind
makes can break. And when reliability meets Mr. Murphy,
the next steps for pilots flying glass are different from those flying steam.
To understand what those operational differences are, we
first need to look under the cowl and understand the magic
that drives the displays. While the system architecture of
glass panel avionics varies by manufacturer and model, all share some basic DNA: the “glass” display itself, the pilot
interface, and the black boxes that drive the system. Let’s
start with the boxes.Little Boxes
A glass panel system is controlled by two different black boxes, in concept (more on that in a moment). The first
box is called an attitude and heading reference system, or
AHRS in our acronym-laden lexicon. The AHRS is respon-
sible for interpreting pitch, bank, and heading info. It does
this using accelerometers, mini gyros, a magnetometer, and

of glass panel avionics varies by
manufacturer and model, all share
some basic DNA: the “glass” display
itself, the pilot-interface, and the
black boxes that drive the system.
May/June 2024 19
… well … magic. The second box is the air data computer,
or ADC, and it’s responsible for altitude, airspeed, and
vertical speed number crunching and display.
There may be one of each type of box in the aircraft, or,
in some installations, there may be dual AHRS and/or dual
ADCs. Increasingly, there are units in the field where the ADC and the AHRS systems are combined into a single
box, called, you guessed it, an ADAHRS. And, in some
systems, the boxes themselves are gone, with the hardware for both built right into the pilot display, an approach that
greatly simplifies installation, and reduces weight, cost,
and complexity.
All this variability, along with the rapid pace of techno-
logical advancement in contemporary avionics, means that you need to spend some time with the Pilots Operating
Handbook (POH) and/or flight manual supplement for
any glass panel-equipped aircraft you fly so that you know how the systems are laid out. Flying glass without
this knowledge would be akin to jumping into a strange
airplane without first understanding how its fuel system is
designed. Not to mention, it’s your responsibility under 14
CFR section 91.103, Preflight action, to familiarize yourself with all available information regarding the flight, which
includes the proper use of avionics installed in the aircraft.
Pilot Interface
The newest glass panel systems are driven by touch
screens that feature smartphone-esque icons sporting
highly intuitive menus. That said, the bulk of the glass
systems found in the general aviation fleet are still button,
knob, and softkey driven, often with less than intuitive
menus and button press chains required to achieve the desired results. These analog-entry glass panel systems all
feature inverse workload: once mastered, they are great
workload reducers in the air; but to master them, expect significant ground study.
:(
ERROR
To avoid draining the aircraft’s battery, a ground power
supply is recommended for in-airplane ground work. As an
alternative, investigate the availability of flight simulators
or training devices in your area that match up to the avion-
ics in the aircraft you will be flying. Sims have several other
advantages over sitting in the airplane pressing buttons and
practicing flows, including the fact you can practice (safely) in simulated flight, as well as on the ground — and they are
cost-effective compared to burning avgas or JetA.
Additionally, some glass avionics systems have “emula-
tors, ” or desktop computer programs that mimic the flight deck systems so that you can learn — and keep sharp with
— the flows from the comfort of home.
Two Screens
The vast bulk of contemporary glass installations on light GA airplanes feature a pair of display panels, the pilot side
panel being called the primary flight display, or PFD; and a
second display of the same size on the copilot side called an
MFD, for multi-function display. The PFD is generally used
to display the flight instruments, while the MFD displays navigation and in some cases, engine data.
The beauty of two screens, beyond being beautiful to the
eyes of many pilots, is the fact that the screens can often flip-flop data. So not only do the dual screens provide a
greater ecosystem of situational awareness, but they also
serve a redundancy role. If the PFD screen suffers a failure,
the flight data can merely be shifted to the MFD or in some
cases, a backup electronic display.Contrary to popular belief, a glass

20 FAA Safety Briefing
Of course, now everything you need to see and know to
control flight is on the wrong side of the airplane. So here’s
your first tip and challenge: on your next instrument profi-
ciency check, shoot an approach using the MFD. Flop your
data and dim, or cover, your PFD — as, generally speak-
ing, most manufacturers discourage disabling the PFD by pulling its circuit breaker.
Bonus points for getting with a flight instructor to get
some right-seat time. If you are flying alone and lose your PFD, that experience will make MFD flying more natural.
That said, if you are not an instructor yourself, you might
find the landing sight picture (and the opposite hand
throttle/yoke operation) disconcerting at first, which is why
some practice with an instructor is in order.
Of course, in a real-life display failure, you are now
essentially flying on one mag. Sure, like magneto systems, the odds of losing both are pretty remote, but why take the chance? If you’ve lost one display, it’s time to get on the
ground at the nearest airport.
Reliability’s Weakness
Despite the greatly improved reliability of glass avionics
compared to legacy avionics, if there is a failure in a glass
system, their architecture makes them more prone to
system-wide failures. That means you can lose all of the
flight data, compared to analog systems failures, where
you are more likely to only lose either the air-driven or power-driven instruments — leaving you with at least a
50% solution.
Hence, in glass flight decks, there is a need for
standby instruments.
Standbys
Standby, or emergency backup instruments, might be a set
of analog instruments, or they can be an independent min-
iature glass panel system. Either way, the standby system is
your lifeboat in the “IFR sea. ” Should the worst happen to
your primary system in hard IFR, you can still aviate and
navigate to an island of safety.
At least in theory.
Because the reality is that standbys are both small and
inconveniently located, typically low down on the panel.
Y es, you can fly on them. And yes, it will be a “stressfest. ”
So that’s your second tip and challenge for today: on your
next IPC, shoot a hooded approach on your standbys.
It’s Not as Modern as You Think
Contrary to popular belief, a glass panel system isn’t totally high-tech. The ADC still uses the aircraft’s ol’ fashioned
pitot static system to connect to the flight environment.
That, in turn, means that contemporary glass panels can
fall victim to the same pitot-static failures that legacy
avionics do, so it pays to review the symptoms of pitot and static blockages. Also contrary to popular belief,
the systems won’t necessarily alert you to a pitot-static
problem, and, for the same reason, it can be hard for pilots to recognize such failures in analog systems — they are
subtle and tricky to recognize.
Power Hungry
When it comes to being prepared for emergencies, the
number one thing to understand about glass avionics
actually has nothing to do with the glass itself directly, but
rather with the glass's food. Modern avionics have fero-
cious appetites for electricity. So much so, that an alternator
failure is possibly a greater emergency than an avionics failure. This is because once the battery is drained — and
the battery-backup, if so equipped — the glass shuts down
along with the radios and all the rest.
An alternator failure in a glass-equipped flight deck is a
much more serious matter than it is in a legacy flight deck. First off, once the battery is dead, all flight instrument
data on the glass is lost — rather than just a portion of it.
Additionally, the time from alternator failure to system failure is dramatically reduced, due to the power-intensive
nature of glass avionics.
In the case of an alternator failure in a glass flight deck,
it’s critical to quickly shed load on the electrical system. Unplug any personal devices that are suckling on the
airplane’s USB ports. Then promptly follow the checklist to
shut down any unnecessary aircraft power usage.
Speaking of unnecessary power use, in IFR conditions,
consider proactively lightening the load on your electri-cal system. This means not taxing the aircraft’s electrical In the case of an alternator failure in a
glass flight deck, it’s critical to quickly
shed load on the electrical system.
May/June 2024 21systems by using it as a charging port for crew and passen-
ger tablets, phones, or laptops — their charging load can
increase the risk of an electrical system failure.
Lastly, don’t expect the lights to stay on as long as the
POH says they will after an alternator fails; that number
is based on a factory-new battery. As batteries age, their stored load capacity decreases. In an alternator failure, the
clock is ticking on your glass avionics. Actually, it’s not so
much a clock, as a stopwatch. It is critical to get to VFR conditions, or safely on the ground as quickly as possible.
The Right Stuff
In all flying, the key to emergency survival is preparedness. In the case of glass IFR flight, avionics failures are less
likely, but when failures happen, they are more likely to be
widespread. Additionally, know that glass avionics are more
vulnerable to aircraft electrical system failures than legacy
systems are, and be ready to act swiftly.
For maximum preparedness, take the time on the
ground to study the architecture of the glass panel systems of any glass aircraft you fly. Practice flows — standard, atypical, and abnormal/emergency — parked on the
ground, in a sim, or using an emulator. And review those
tricky pitot-static failures, and how they would manifest on
your glass display.In the air, put those IPCs to good use by practicing with
the MFD and the standbys. Consider some right-seat time.
Right-screen, right-seat practice equips you with the right stuff for a glass emergency.
In flight, keep the load light — the power load. Just like
weight affects aircraft performance, so too does the load on
the electrical system.
And should it happen — should the infamous red “Xs”
appear, or a screen go dark — unplug and navigate to the nearest port in the storm, be that below the weather, above
the weather, or on the ground at the nearest airport or airstrip. Time is not on your side. But if you are prepared,
there will be time enough.

CHECKING YOUR CHECK
As we delve into all things instrument
flight rules (IFR) in this issue, we see
that currency and proficiency play a
big part in flight safety. Many of us
aren’t everyday aviators, so when we
get a chance to take to the air, we want to use that time to do something fun,
not just bore holes in the sky, pun
intended. This can lead to an attempt to minimize the “work” we must
do to stay proficient. Sometimes we
clear the bar just enough to meet the
legal standards and move on to more
enjoyable endeavors, an approach that can put us in a potentially deadly
situation. When it comes to flying,
especially instrument flying, being just good enough isn’t good enough.
Where to Start?
Title 14, Code of Federal Regulations
(14CFR), section 61.57(c) lays out
the basic currency requirement to fly
under IFR: six approaches, holding,
and intercepting and tracking of
courses, all within the last six calendar months. This would be the “easiest”
way to stay current as these can be
done using actual or simulated instru-
ment conditions and don’t require
evaluating your skills. Y ou may need a safety pilot if you are meeting the
requirements using a view-limiting
device, but the safety pilot is not required to be an instructor. This is
the equivalent of your take-offs and
landings for passenger currency. So long as you do them, and the aircraft is airworthy after that, you’ve met the
requirement. Y ou may also complete
the same tasks in paragraph (c) in
an approved Aviation Training
Device (ATD) without the involve-ment of an instructor.
The other path to IFR currency is
found in 14 CFR section 61.57(d), the instrument proficiency check (IPC).
An IPC may be accomplished instead
of the requirements in paragraph (c)
above but must be completed if cur -
rency lapses. Some pilots prefer to do
an IPC because, from a time and cost
perspective, they can be “cheaper. ”
Even the most efficient routing is unlikely to allow you to do six
approaches, holding, etc., in less than
a few hours of flying time, especially
in busier areas where you may have
to be sequenced in long queues. The requirements of an IPC include air
traffic control clearances and proce-
dures, flight by reference to instru-
ments, navigation systems, instrument
approach procedures, emergency operations, and postflight proce-
dures. For more information on how
to conduct an IPC, the FAA issued Advisory Circular (AC) 61-98D.
While the AC covers many different
checks, Chapter 5 is the most relevant
to this subject. Chapter 5 is brief (less
than four pages) but covers almost everything you need to know about
an IPC from an instructor’s point of
view. From there, we can extrapolate what will likely come up on an IPC as
a participant.
Lean In
In the AC under Preflight
Considerations, there is a key state-
ment that may get overlooked: “The
flight instructor should structure an IPC like that of the flight review, tailoring the check to the needs of the pilot . ” [Emphasis mine]. It goes on
to suggest that the instructor should analyze the pilot’s experience, back-
ground, and abilities utilizing realistic
scenarios to ensure that the pilot is ready to encounter IMC on their own.
The instructor is then supposed to
review their plan of action with the pilot so that everyone agrees on the
check terms. This is where it’s essen-
tial as the pilot receiving the check
that you are really honest with the
instructor. Rather than trying to get away with the minimum, you should
lean in and use the IPC as a real test
of your skills. It may make for a longer
IPC, but the end result is a higher skill
level and greater confidence, which may make the difference when things
start to get rough.

24 FAA Safety BriefingDRONE DEBRIEF drone safety roundup
REBEKAH WATERS
KEEPING YOUR EYE ON THE DRONE
Anyone who’s ever played baseball
likely remembers the first thing they
learned: “Keep your eye on the ball. ”
Y ou’ve probably passed on this sage
tip at least once. Well, when it comes
to drone flying, keeping your eyes on your drone is not only a great tip, but
it’s also mandatory.
Whether you are a part 107 pilot,
or you fly for fun as a recreational flyer, you must maintain visual line
of sight (VLOS) with your drone
at all times. This requirement can be
one of the most confusing parts of flying a drone. One reason is that the
FAA has not set a maximum distance
for this requirement. This is because the maximum distance you can
maintain VLOS depends on several
factors, such as the size of your drone,
weather conditions, your visual acuity,
and obstacles, to name a few.
Why VLOS?
To understand how to effectively
keep your eye on the drone, let’s look
at why this is a requirement. Section 44809(a)(4) tells recreational flyers:
“The aircraft is operated in a manner
that does not interfere with and gives way to any manned aircraft. ” Drone
pilots must “see-and-avoid” manned
aircraft. Some might ask, “Why can’t
I use my camera to satisfy these
requirements?” With today’s tech-nology, even the best cameras cannot
replace the function of a pilot’s ability
to see-and-avoid. In a crewed aircraft,
the pilot can turn and look in any
direction quickly to scan for obstacles. An effective scan must encompass all
areas of the environment in which a
hazard could be present. In this case, think about yourself as the pitcher
instead of the batter. If you have
“tunnel vision” from relying on your camera, would you notice the runner trying to steal second? Y ou must use
your eyes, unaided by any device
other than corrective lenses, to see-
and-avoid other aircraft, people, and
property on the ground.
The “And” and “Or” of VOs
Another common area of confu-
sion is that the FAA uses both “and”
and “or” when talking about visual
observers (VOs). Section 107.31(a),
Visual line of sight aircraft operations ,
says “the remote pilot in command,
the visual observer (if one is used),
and the person manipulating the
flight control of the small, unmanned
aircraft system must be able to see the
unmanned aircraft throughout the
entire flight. ” It goes on to list four
things that must be accomplished
by VLOS: know the location of the drone; determine its attitude,
altitude and direction; watch the
airspace for other air traffic or
hazards; and make sure the drone
does not endanger the life or property of another. But in section
107.31(b) it says, the ability to do these four things must be exercised by the remote pilot in command and the
person manipulating the controls, or
the visual observer.Let’s help this make sense. First,
how can the remote pilot in command be someone other than the person
manipulating the controls? Well, you
may be training someone to fly, but
you are still the one in charge and ulti -
mately responsible for the flight. Next,
is it and or is it or ? VOs could be used
for several reasons like allowing you
to use your camera for photography
or giving you time to look away from
the drone to complete other aspects
of your operation. What section
107.31(b) says is that no matter what is happening, at least one person in
your operation must have eyes on the
drone and the surrounding airspace. What section 107.31(a) says is that
everyone involved in the operation
must have the ability to see the drone
even if one of them looks away from
the drone. In other words, if your VO alerts you to a potential hazard, can
you immediately put your eyes back
on your drone?
Remember, when it comes to
VLOS, your primary responsibility is to see-and-avoid other aircraft.
Y our drone is the ball, not the image
sent back to you by the camera. So, whether it’s you or your visual
observer, make sure you always keep
your eye on your drone!

MASTERING BALLISTIC PARACHUTE SYSTEMS MAINTENANCE
A pilot entered the clouds in instru-
ment meteorological conditions
(IMC). Around the same time, he
experienced engine failure and the
aircraft descended abruptly. With all
the alert systems squawking, he didn’t have time to wonder if his ballistic
parachute system was properly main-
tained and inspected. He only had
time to make the split-second deci-sion to deploy it and bring the aircraft
down safely. If he had waited even 30
seconds longer, it could have been too
late. He, and his passenger, escaped major injuries thanks to this system,
and the story has a happy ending.
Ballistic parachute systems are
designed to safely return an aircraft to the ground in the event of an emer -
gency, such as engine failure, struc-tural damage, or other hazards that
might lead to a crash. The systems are launched by a solid rocket that
fires at over 100 miles per hour and
deploys a parachute in less than one second. They come installed standard
on some Cirrus aircraft and can be
installed on many other small aircraft,
including helicopters.
These systems require regular
inspection and maintenance as speci-fied by the manufacturers. Mechanics
must receive proper training on
the maintenance procedures spe-
cific to the system installed on the aircraft they are inspecting and/or maintaining. Before beginning main-tenance, it’s important to familiarize
yourself with the emergency precau-
tions related to the deployment and
operation of the rocket to prevent
major injuries or even death from accidental rocket activation.
When conducting a maintenance
inspection, look for signs of wear,
corrosion, or damage as directed by the manufacturer. Always follow the
manufacturer-recommended replace-
ment schedule for components such
as the rocket motor, parachute, and lines. Just because it is sitting, unused,
doesn’t mean it has maintained being
in a safe condition for flight. These systems also need periodic testing.
Always follow the manufacturer's
directions for testing. Don’t forget
to document what you’ve done.
Maintain detailed records of inspec-tions, replacements, and any main-
tenance performed in the aircraft
maintenance records.
Other required maintenance
includes mandatory and unscheduled canopy inspections and repacks by the
factory. This involves removing the
parachute container from the aircraft for inspection and repacking them at
regular intervals. These intervals vary
depending on the style and whether
the system is mounted internally or
externally. Check the manufacturer recommendations for specific sched-
ules. Unscheduled factory inspections
are required in certain situations. These include signs of damage or
tearing and any time the parachute
is deployed, whether accidentally or intentionally. These systems must also be sent back to the factory when-ever there is a breach of the inner
cap on the canister or upper cap, or
if the parachute itself has gotten wet or exposed to other contaminates. Finally, if there is any situation where
you might be uncertain of the reli-
ability of the unit due to any type
of abuse, exposure, or wear, remove
it and send it for an unscheduled canopy inspection and repack.
Rocket replacement is another
important part of periodic mainte-
nance. All rocket motors have expi-
ration dates and must be replaced accordingly. These dates are printed
on the placards on the sides of the
parachute container and rocket. But
don’t ship the rocket back! Without
the proper packaging and documenta-tion, it is illegal and dangerous to ship
loaded rockets and propellant. Instead,
contact the manufacturer for service instructions on how to safely disassem-
ble and dispose of the rocket properly.
Even when inspected and main-
tained correctly, these systems have
a maximum service life, so check with the manufacturer to know when
the system will need to be replaced.
Hopefully, most pilots won’t ever need
to use this last resort feature. If the
time does come to use it, it will be too late to make sure it’s in good shape. So,
if you inspect an aircraft equipped with a ballistic parachute system, always
follow the manufacturer’s guidelines.
Routine inspection and maintenance
are crucial and could make the differ -
ence between life and death.

VERTICALLY SPEAKING safety issues for rotorcraft pilotsGENE TRAINOR
SIMULATORS SAVE LIVES
Since people began flying helicop-
ters, weather has played a large role
in accidents. Unintended flight into
instrument meteorological condi-
tions (UIMC) is among the most
dangerous situations that can con-tribute to an accident.
For the layman, UIMC occurs
when pilots unintentionally fly into weather where visibility is so limited
that all they can see are clouds and/
or precipitation. It also can occur over
unlit terrain or a large body of water
on moonless nights when a visual horizon is not visible.
If pilots
fly lower in an attempt
to main-
tain visual
contact with
the ground, they risk
hitting towers, wires, terrain, or other obstacles. If they continue at
their present altitude or higher, they
risk UIMC. This can result in spatial disorientation, which occurs when
pilots cannot determine a helicopter’s
position, motion, and altitude relative to the earth or their surroundings.
Pilots will then need to rely on their
helicopters’ instruments to maintain
aircraft control, turn around before
entering these conditions, or just land. Without adequate training, this can be
a terrifying and dangerous situation.
Consider Simulators
Simulators allow pilots to experience
hazardous situations as if they were in
an aircraft but in a safe environment.
The FAA urges pilots to use simula-tors to practice how to recover from
UIMC. Pilots also can assess the risks
of continuing with a flight. The United States Helicopter
Safety Team (USHST), a govern-ment-industry safety advocacy group,
issued a helicopter safety enhance-
ment (H-SE) in 2018, calling on the helicopter community to increase
simulator training. Not only do sim-
ulators help pilots navigate UIMC,
spatial disorientation, and other risky
weather-related conditions, they can also help with better decision-mak-
ing; loss of control; loss of tail rotor
effectiveness; and vortex ring state
conditions. Several of these situations
occur simultaneously.
We recognize that some pilots may
lack access to simulators. Properly trained instructors using view-limit-ing devices in flight represent a good
alternative and provide real-world
conditions conducive to spatial disori-
entation training.
Simulator Training Matters
The Rotorcraft Collective, a gov-
ernment-industry group, recently
published a video that retells the time
flight instructor Terry Palmer met some pilots waiting for their helicop-
ter to be serviced in Shreveport, La.
While they waited, she offered UIMC instruction in her flight simulator.
The pilots crashed in every scenario.
These pilots had traveled to
Shreveport under visual flight rules.
Clouds were minimal, and the pilots could see obstacles and terrain
several miles ahead of their helicop-
ter’s flight path. After their UIMC training, the pilots were en route
back to Boston when they encoun-
tered weather outside New Y ork City.
They landed their helicopter. They
knew they lacked the expertise to push through thanks to the simula-
tor training. One of the pilots called Palmer to tell her that she saved
their lives. According to Palmer, they scheduled additional simulator
training to improve their instrument
proficiency. Watch the video at
bit.ly/3xsHFFp.
The USHST Safety Analysis Team
(SAT), the group that developed
the simulator H-SE, among others,
studied 104 fatal helicopter accidents from 2009 to 2013 and determined
that 52 accidents fell into three
occurrence categories: UIMC, loss of
control, and low-altitude operations.
Of these 52 fatal accidents, the team determined that 21 could have been
avoided through simulator training.
More than half (12) were UIMC.
“This H-SE targets greater use
of simulation at all levels … initial professional helicopter training and
during recurrent training sessions, ”
the SAT’s report states. “This will allow pilots to learn from their mis-
takes in a safe environment and will make them less likely to repeat the
error during actual flight. ”
UIMC is a risk every pilot faces.
Be prepared. Train in a simulator.

Auspicious Admission
I was a Delta Airline pilot for 34
years, and now I’m retired and flying general aviation operations.
I was familiar with the Aviation
Safety Reporting System (ASRS) and Aviation Safety Action Program
(ASAP), and we used to be able to
report within 24 hours an incident
and then get maybe get a letter of
caution or warning instead of a violation, if warranted. Do we have
anything like this self-reporting pro-
gram for me now? Thank you!
— Chris
Hi Chris. Thanks for reaching out
and welcome to the general aviation
community! Fortunately, the ASRS
also applies to part 91 flying, and we
encourage you to participate!
NASA ’s ASRS welcomes all users
to report any safety issue, especially information that could
help prevent
an accident. They protect
your iden -
tity and the identity of all
other parties involved. The
personally
identifying
information
will not be shared outside of NASA,
including with the FAA, unless the
report involves criminal activity or an
accident. Further, if the event became
known to the FAA by some other means and the FAA takes legal enforce-
ment action, then the FAA will not
impose any civil penalty or certification
suspension if certain criteria are met.
Regarding the 24-hour period for
filing a report — while you can submit a report at any time, you are encour -
aged to complete the report in as timely
a manner as practical. Doing so helps
ensure that any critical safety-related
information is relayed by NASA to the
FAA sooner. It also helps you as the reporter to remember all the details of
the event. However, if the reporting is
to be used for waiver of legal enforce-ment sanction, then the report must
have been filed within 10 days after the
event (or the date when you became
aware or should have been aware there
was a violation).
ASRS collects the de-identified infor -
mation and the reporter’s narratives to spot deficiencies and discrepancies in the National Airspace System (NAS). These narratives provide a rich source of information for understanding the nature of hazards and enhance the basis for human factors research and
recommendations for future operations.

TOM HOFFMANN
WITH MY HEAD IN THE CLOUDS
Many people say imitation is the sin-
cerest form of flattery. I agree in some
cases, but I’ d argue there’s great value
in authenticity. Various businesses
have touted that truth in campaign
strategies over the years. A few that stand out to me are Coke (It’s the
Real Thing), Wild Turkey (Accept No
Imitations), and Porsche (There is No Substitute). It harkens to consumers
having a “genuine” experience. While
these are all fairly subjective regard-
ing what is actually the best, there’s
something to be said about enjoying or experiencing something that is
the standard-bearer, or as many soda
drinkers would affirm, the real thing.
In this IFR-focused issue, we point
out the many ways and means that pilots have to gain flying experience
when solely guided by instruments. It
might involve simu-
lation training firmly on the ground using
a full flight simulator,
flight training device,
or an aviation training
device. If it’s a nice
sunny VFR day,
it might involve
launching into
the air with a
view-limiting
device, or if the
weather works
out, flying in
actual instru-
ment meteoro-
logical condi-
tions (IMC)
— the real deal.
While receiving training for
my instrument
rating during a
New England fall, I didn’t have to rely much on the first two options as IMC was pretty
plentiful. Up to that point, I had only
received limited IFR training under a
hood or view-limiting glasses. I have
nothing against those at all, as I know IMC opportunities are difficult to
seek out in some parts of the country.
However, having the experience of real-world instrument conditions did
make a big difference, in my opinion.
First, there are some visual, aural,
and sensory experiences offered by
IMC flight that are difficult to recreate in a simulated environment or with
view-limiting devices. On the latter,
they can help improve your instru-ment scan, but gaps in these devices
can inadvertently clue in a student to
the type of scenario or unusual atti-
tude a flight instructor is attempting
to present.
There are also a few subtle things
you can only experience in actual IMC, like the buffet you might feel
when you first enter a cloud layer, the
sounds and varying levels of visual obscuration you might encounter
when flying through precipitation, or
simply just seeing your windshield completely enveloped in gray. To a
novice flyer, these experiences could
be quite startling and anxiety-in-
ducing, especially during an initial
encounter. I felt that having the ability to see, hear, and feel these subtleties
during training provided me with an
additional layer of confidence and preparation that I carried with me on
subsequent IFR flights.
The gradual and often hard-to-de-
tect onset of IMC conditions during
flight is also difficult to simulate. Real-world inadvertent IMC encoun-
ters don’t typically mimic the binary
situation experienced when donning a hood that instantly places you in the clouds. There’s value in being able
to see and experience firsthand that
gradual loss of visibility and ground
reference leading up to IMC, and
being able to correctly react before the situation worsens. Look no further
than the sheer volume and fatality rate
of VFR into IMC accidents to see the life-saving value of this experience.
Y et another benefit is the ability to
set more realistic personal minimums
based on these real-world experiences.
Personal minimums should be set to provide a solid safety buffer between
the skills required for the specific
flight you want to make, and the skills
available to you through training,
experience, currency, and proficiency. An essential step in establishing per -
sonal minimums includes assessing your experience and comfort level with certain flight conditions (e.g.,
low ceilings and visibilities).
Be honest in your assessment, but
don’t be afraid to adjust those min
imums as you gain experience with certain conditions. Having pre-set
hard numbers based on specific per -
sonal parameters you’ve established with firsthand experience will make it much easier to make smart no-go
or divert decisions than having a
vague sense that you can “probably” deal with the conditions you’re in.
It’s a case where having your head
in the clouds can actually help you
see more clearly.THE GRADUAL AND OFTEN
HARD-TO-DETECT ONSET OF IMC CONDITIONS DURING FLIGHT IS DIFFICULT TO SIMULATE.

STEPHEN BROWN
Aircrew Program Manager, FAA’s Boston Flight Standards District Office
What do a lobster, a pot, and chowder
have in common? To New England
local Stephen Brown, they are the
three components needed to make
a five-star instrument-rated pilot —
translated to qualification, currency, and proficiency. A safe pilot under -
stands all three.
Our crustacean friend can nav-
igate the depths without the need
to see, even when Poseidon churns
up the seafloor, causing subaquatic
instrument meteorological conditions
(IMC). One could say he’s a qualified captain, but that doesn’t mean he
won’t get caught in a trap.
“Each year, we have so many
people who are instrument-rated and continue into IMC conditions
they should be avoiding. They think
they can do it because they are rated, ”
Stephen explains. “Being qualified is great, but that should be considered a
knowledge/decision skill, not a regu-
lar operational skill. ”
If you don’t want to go from lobster
pot to stock pot, stay current. Think of currency as your license to learn.“What I see as being current for
IFR flights is that you have demon-
strated the skill set to go out and
learn more, ” he notes. “Y ou can fly in
selected conditions to improve your
skills and have an instructor conduct an instrument proficiency check. Y ou
need to hone and develop those skills. ”
This is where our culinary trifecta
is perfected into a good cup of chow-der — with proficiency. That means
you can apply those skills in varying
conditions and situations and know
the conditions and situations to avoid.
“ A proficient pilot knows that
the hardest decision is the internal debate to cancel before a flight, ” he said. “Being a proficient pilot also
means being able to fly your aircraft
without automation in difficult
situations. It involves being able to change the level of automation you are using at any given moment with-
out it being a factor. ”
With more than 8,000 hours as an
airplane and glider flight instructor, Stephen is still all about improving his
skills and flying as much as he can. He
has flown more than 100 makes and
models ranging from powered para-chutes to gliders, ski planes, and small
corporate jets.
Before joining the FAA in 2009,
Stephen earned a bachelor’s degree in
aviation from Daniel Webster College and a master’s degree with a focus in
simulation from Embry-Riddle Aero-
nautical University. He has worked or flown for Comair, Embry-Riddle,
Sporty’s Pilot Shop, and Cape Air. He
was also an aviation program director at the University of Cincinnati and Daniel Webster College.
At the FAA, Stephen’s most memo-
rable role was his nine-year stint as an FAA Safety Team (FAASTeam) pro-gram manager where he was integral in educating fellow pilots. Now, he is an aircrew program manager in the
Boston FSDO assigned to Cape Air.
He oversees the regulatory involve-
ment of the regional airline’s aircrew
designated examiners.
“The funny thing that led me to
the FAA is an intervention at Air -
Venture in Oshkosh. I would occa-sionally help with what is now the
KidVenture portion, maybe do a
seminar or two, and would just be
generally involved, ” he reminisces.
“One day, a bunch of us were watch-ing the aerial performance from
some picnic tables, and I realized
that all the FAA people I had worked with were sitting around me. One of
them looked at me and said, ‘Steve,
this is an intervention. ’ That’s when I
decided I needed to come to work for
the FAA, somehow, some way. ”
So, this is your intervention: next
time you fly for that $100 hamburger — try upgrading to a lobster chow-
der. And to keep you safely out of
the stock pot, remember the three ingredients needed to make a five-star
instrument-rated pilot: qualification,
currency, and proficiency.
