Subject: Upset Prevention and Recovery Date: 4/14/15 AC No: 120-111
Training Initiated by: AFS-200 Change:
This advisory circular (AC) describes the recommended training for airplane Upset Prevention
and Recovery Training (UPRT). The goal of this AC is to provide recommended practices and guidance for academic and flight simulation training device (FSTD) training for pilots to prevent developing upset conditions and ensure correct recovery responses to upsets. The AC was created from recommended practices developed by major airplane manufacturers, labor organizations, air carriers, training organizations, simulator manufacturers, and industry representative organizations. This AC provides guidance to Title 14 of the Code of Federal Regulations (14 CFR) part 121 air carriers implementing the regulatory requirements of
§§ 121.419, 121.423, 121.424, and 121.427. Although this AC is directed to air carriers to
implement part 121 regulations, the FAA encourages all airplane operators, pilot schools, and training centers to implement UPRT and to us e this guidance, as applicable to the type of
airplane in which training is conducted.
Although a stall is by definition an upset, stall prevention and recovery training is contained in
the current edition of AC 120-109, Stall Prevention and Recovery Training.
Core principles of this AC include:
• Enhanced instructor training on the limitations of simulation.
• Comprehensive pilot academic training on aerodynamics.
• Early recognition of divergence from intended flightpath.
• Upset prevention through improvements in manual handling skills.
• Training that integrates crew resource management including progressive intervention
strategies for the pilot monitoring.
CAUTION. Prior to commencing UPRT, air carriers should review and
implement FAA NSP Guidance Bulletin 11 -05, FSTD Evaluation
Recommendations for Upset Recovery Training Maneuvers to ensure FSTDs
are specifically evaluated for UPRT maneuvers. Otherwise, negative transfer
of training could occur.

CHAPTER 1. INTRODUCTION
1-1. BACKGROUND. Based on accident reviews, a concern exists within the Federal Aviation
Administration (FAA) and industry regarding loss of control in- flight (LOC -I) accidents. As
LOC -I is generally a consequence of an airplane upset, the FAA reconvened the Section 208
Aviation Rulemaking Committee (ARC) in 2011 to provide recommendations for Upset
Prevention and Recovery Training (UPRT). The FAA, International Civil Aviation Organization
(ICAO), and the European Aviation Sa fety Agency (EASA) then decided to combine efforts to
identify and establish an acceptable approach to reducing upsets. ICAO sponsored meetings in 2012 during which the 208 ARC, Civil Aviation Authorities, and subject matter experts
participated in focused discussions on LOC-I accidents and upset recovery training. This combined effort was called the loss of control avoidance and recovery training (LOCART) initiative. Additionally, the Commercial Aviation Safety Team (CAST) studied 18 accidents and incident s resulting from a lack of awareness of either the airplane’s energy or attitude. One
recommendation of the team was for air carriers to conduct upset training using realistic
scenarios. This AC is based upon the recommendations of both LOCART and CAST.
1-2. GENERAL. Operational data indicates that some pilots have failed to prevent airplanes
from entering a fully developed upset and have not been able to properly recover from such
events. In addition to stall training, UPRT is an essential training element to r educe loss of
control events or, if they occur, enable recovery to normal flight.
1-3. PART 121 REQUIREMENTS. All part 121 air carriers, including those who train under
an Advanced Qualification Program (AQP), are required to conduct UPRT beginning
March 12, 2019. The requirement for part 121 pilots to receive upset training is statutorily
mandated in Public Law 111-216, Section 208 and the FAA does not have the authority to exempt any part 121 air carrier from this requirement. Air carriers must include UPRT fo r
pilots during:
• Initial training,
• Transition training,
• Differences and related aircraft differences training (if differences exist),
• Upgrade training,
• Requalification training (if applicable), and
• Recurrent training.
1-4. AQPs. For simplicity, because the requirements for UPRT are contained in part 121
subpart N and appendix E, the terminology used in this AC is consistent with those regulations. Air carriers with an AQP should use the content of this AC in conjunction with the current edition of AC 120-54, Advanced Qualification Program.
1-5. AIR CARRIERS CONDUCTING TRAINING IN AIRPLANES.
a. For part 121 air carriers, § 121.423 requires the following extended envelope training
maneuvers discussed in this AC to be conducted in a Level C or higher full flight simulator
(FFS): manually controlled slow flight, manually controlled loss of reliable airspeed, manually
Par 1-1 Page 1
4/14/15 AC 120-111
controlled instrument departure and arrival, and upset recovery maneuvers. Air carriers are
encouraged to use the highest fidelity level FFS available.
b. In accord ance with § 121.423, part 121 air carriers may submit a request to the
Administrator for approval of a deviation from the FFS requirements to conduct the extended envelope training using an alternative method to meet the learning objectives of § 121.423.
c. Although the training in this AC is designed to be conducted in an FSTD, those
operators using airplanes for training can incorporate into their training programs all of the academic elements and some of the flight training elements. Operators should carefully select flight training maneuvers and employ risk mitigation strategies. Airplanes used for flight training elements should be those designed for the specific maneuvers being conducted, and training programs should use instructors specifically qualified to conduct UPRT in airplanes. The FAA recommends that any operator conducting UPRT in airplanes follow the guidance and associated risk mitigation strategies contained in ICAO’s Doc 10011, Manual on Aeroplane Upset Prevention and Recovery Training.
1-6. DEFINI TIONS/TERMS. For the purpose of this AC, the following definitions and terms
are provided:

CHAPTER 2. UPSET PREVENTION AND RECOVERY TRAINING (U PRT)
PRINCIPLES
2-1. GENERAL. An effective UPRT curriculum provides pilots with the knowledge and skills
to prevent an upset, or if not prevented, to recover from an upset. Training should focus on
preventing upsets rather than waiting to recover from one. The focus on prevention is a significant shift from previous upset or unusual attitude training, which primarily focused on recovering from a fully developed upset. Prevention training prepares pilots to avoid incidents, while recovery training intends to avoid an accident if an upset occurs.
2-2. TRAINING PHILOSOPHY. While basic aerodynamics and unusual attitude
1training are
required elements for a pilot’s private, commercial, and airline transport pilot (ATP)
certifications, it is important to reinforce and expand upon this certification training throughout a pilot’s career. This advisory circular (AC) describes the academic and flight training components of a comprehensive UPRT curriculum, requirements for UPRT instructors, flight simulation training device (FSTD) requirements, upset recovery procedures, and sample UPRT scenarios.
a. Training Goal. A pilot who has successfully completed UPRT will demonstrate
knowledge and skill in preventing, recognizing, and, if necessary, recovering from an upset.
b. Training Methodology. UPRT is to be conducted as train- to-proficiency, i.e., training
will continue until completion criteria are met.
NOTE: UPRT is not to be evaluated in proficiency checks, line- oriented
evaluation (LOE), or by other jeopardy events.
c. Completion Criteria for Prevention. Prevention is the primary goal o f UPRT,
including timely action to avoid progression toward a potential upset.
• When acting as either pilot flying (PF) or pilot monitoring (PM), actively scans the internal and external environment and identifies and alerts the crew to factors that may lea d to divergence from the desired flightpath.
• When acting as PM, creates, communicates, and manages alternative courses of
action that reduce the likelihood of an upset.
d. Completion Criteria for Recognition. Timely action to recognize divergence from the
intended flightpath and interrupt progression toward a potential upset.
• When acting as PF, prompt recognition of divergence from intended flightpath or uncommanded changes to the aircraft flightpath.
• When acting as PM, active monitoring of aircraft state and flight parameters and prompt callout of divergence from planned or briefed flightpath.
• Take prompt action (if PF or through callouts if PM) to correct a divergence from the intended flightpath and interrupt progression toward a potential upset.
1 This training is incorporated into “Upset Recover Techniques” in Appendix 1, Section 8.
Par 2-1 Page 5
4/14/15 AC 120-111
e. Completion Criteria for Recovery. Timely action to recover from an upset in
accordance with the air carrier’s procedures, or in the absence thereof, in accordance with
recommendations provided in Chapter 4 of this AC.
• A PF will take action, or a PM will call out the need, for timely execution of
recovery priorities: 1) manage the energy; 2) arrest flightpath divergence; 3) recover
to stabilized flightpath.
• Apply (PF), or monitor (PM), appropriate control actions to recover the aircraft
without exceeding aircraft limitations.
• When an upset is precipitated by stall, recover from the stall before initiating other recovery actions.
2-3. IMPORTANCE OF THE UPRT INSTRUCTOR. The key to effective UPRT is the
instructor. The safety implications and consequences of applying poor instructional technique, or
providing misleading information, are more significant in UPRT compared with some other areas of pilot training. Therefore, an essential component in the effective delivery of UPRT is a properly trained and qualified instructor who possesses sound academic and operational knowledge.
2-4. INSTRUCTOR REQUIREMENTS (§§ 121.412 and 121.414). UPRT instructors must
meet the following requirements:
• Hold an ATP certificate and airplane type rating
2 in the airplane for which they are
conducting training.
• Successfully complete the certificate holder’s UPRT program as a stud ent and the
UPRT instructor training in paragraph 2-5 below.
• Be able to teach, assess, and debrief the elements included in the training programs they
are conducting.
• Be trained and qualified to conduct training in the FSTD to be used for the training.
2-5. INSTRUCTOR TRAINING. Instructor knowledge of the subject areas below ensures
accurate UPRT and minimizes the risk of negative transfer of training. The focus of instructor
training should be on the practical application of these principles and the evaluation of a pilot’s
understanding of the airplane’s operating characteristics. Instructor training should include the following and if a regulation is cited, the training is required:
a. Limitations of the FSTD (§ 121.414).
(1) Instructors must complete training on the data and motion limitations for each
specific FSTD used for UPRT with emphasis on areas that have the potential to introduce
negative transfer of training. Training on the limitations of the specific FSTD will enable instructors to provide upset recovery training consistent with the capabilities and performance of the specific aircraft type. This comprehensive instructor training will not only increase instructor
2 A second in command pilot type rating issued under § 61.55 does not meet this requirement.
Par 2-2 Page 6
4/14/15 AC 120-111
standardization and the quality of upset recovery training, but it will also reduce the risk of
negative training that could easily occur with an untrained instructor.
(2) Instructors sh ould learn to brief and debrief pilots on these limitations.
(3) Negative transfer of training has previously occurred as a result of the instructor’s
lack of knowledge of the limitations of the FSTD. FSTD instructors must be aware that valid training may be limited to the parameters to which the FSTD has been programmed and evaluated to conduct. Operating outside of these parameters may result in the FSTD responding differently than the airplane would to a pilot’s control inputs. Motion cueing information may not always accurately simulate the associated forces and rates that could be felt in an airplane.
(4) Instructors must have a clear understanding of the FSTD limitations that may
influence UPRT, including:
• The FSTD’s acceptable training envelope;
• G loading awa reness/accelerated stall —factors absent from the FSTD’s motion
cueing that could be experienced in flight and the effect on airplane behavior and recovery considerations; and
• Significant deviations from the FSTD’s validation envelope could result in an
inaccurate FSTD response. While minor excursions from the FSTD’s validation
envelope may not necessarily invalidate the training, instructors should be aware that the airplane’s response in an actual upset condition may deviate from what is experienced in the FSTD. Particular upset scenarios should be selected and evaluated before training takes place to reduce the likelihood of significant excursions outside of the FSTD’s validation envelope.
(5) Refer to AURTA Appendix 3 -D for more information.
b. Instructor Operat ing Station (IOS) Use (§ 121.414). Instructors must complete
training on the proper operation of the controls, systems, and environmental and fault panels for each specific FSTD used for UPRT. This includes the specific IOS indications and controls that will be used to provide training and feedback during UPRT events.
c. Minimum FSTD Equipment (§ 121.414). Instructors must complete training on the
minimum FSTD equipment required by parts 60 and 121 for each UPRT event. Instructors must understand that UPRT must only be conducted if the minimum FSTD equipment is functional; otherwise, negative transfer of training could occur.
d. Review of Loss of Control In Flight (LOC- I) Events, Incidents, and Accidents.
Training and review of LOC-I events, incidents, and accidents increases knowledge and skill development to recognize and to recover from an airplane upset. A review of LOC- I events will
provide pilots with a focus and a context for the consequences of allowing the airplane to develop into an upset.
Par 2 -5 Page 7
4/14/15 AC 120-111
e. Energy Management.
(1) It is important that instructors not only understand energy management but also be
able to apply it as a means of upset prevention. UPRT instructors should be trained on specific techniques and maneuvers to demonstrate and train energy management principles effectively.
(2) An improper understanding of airplane energy state has contributed to a pilot’s poor
understanding of airplane control. This poor understanding influenced the previous improper training of stall recovery. It is therefore important that instructors understand how energy
management is a factor in all phases of flight, as well as in UPRT.
f. Spatial Disorientation. Instructors should be trained in a variety of causes of
disorientation, prevention strategies, recognition cues, and recovery from disorientation, because spatial disorientation training may not be effectively represented in an FSTD.
g. Distraction. UPRT instructors should have an awareness of how distractions can lead
to an airplane upset and how to effectively use distractions in training. Appropriate use of distractions can also assist the instructor in creating a situation to induce startle. UPRT instructors should learn about different distractions that can affect a flightcrew, such as:
• Communication,
• Heads -down work,
• Responding to abnormal/unexpected events,
• Searching for traffic,
• Flight deck ergonomics,
• Flight deck noise level,
• English language proficiency (from both the pilots and air traffic control (ATC)),
• Airport infrastructure, and
• Flightcrew fatigue.
h. Recognition and Rec overy Strategies. Instructors should be able to convey how to
recognize upset conditions and to apply appropriate recovery strategies. Training should include specific examples, in both academic discussion and practical demonstration .
i. Recognition and Correction of Pilot Errors. Errors may occur in flight operations if
the errors are not identified and corrected during training. Instructors should be aware of the consequences of failing to recognize and correct pilot errors. Instructors should be familiar with common pilot errors, be able to identify the root cause, and provide training to avoid errors and incorrect inputs that can create undesired aircraft states (such as over controlling for Traffic Collision and Avoidance System Resolution Advisories).
j. Type- Specific Characteristics. Original Equipment Manufacturers (OEM) have
recognized that different airplanes have unique characteristics that may both assist in, or deter from, the recognition and recovery of an airplane upset. UPRT instructors should know specific
unique characteristics regarding airplane handling and recognition, such as how the airplane responds while approaching stall buffet or the effects of envelope protection.
Par 2 -5 Page 8
4/14/15 AC 120-111
k. OEM -Specific Recommendations. Evidence indicates that training programs usi ng
operating procedures from one airplane type may have a detrimental effect if carried over to a
different airplane type. This can lead to an upset. Training should use airplane- specific OEM
recommendations and air carrier procedures developed from OEM recommendations for
prevention and recovery from an upset.
l. Operating Environment. Current training does not always take into consideration the
different handling characteristics in all areas of the operating envelope. Instructors should be trained in how to demonstrate the effects of the operating environment, as well as how these will affect the airplane handling characteristics and potentially lead to an airplane upset. This should include how changes in the environmental conditions will affect the airplane . An example is
showing how thrust available varies significantly with altitude by timing how long it takes to change speed by 25 knots during level flight at low and high altitude.
m. Startle or Surprise. Because upsets that occur in normal flight operations are
unplanned and inadvertent, pilots may be startled or surprised, adversely impacting recognition or recovery. Instructors need to plan scenarios to balance potential for startle or surprise while applying sound judgment with respect to realism and fidelity, and respecting the capabilities and limitations of the FSTD. It is crucial for the instructor to adopt and foster a spirit of collaborative learning when inducing startle or surprise so as not to inappropriately attempt to trap a pilot or destroy con fidence in the training session.
n. Benefits of Demonstration in an FSTD. Some elements of UPRT may be more
assessable, trainable, and effective when FSTD instructors demonstrate them from a pilot seat .
o. Assessing Pilot Performance to Completion Standards. Instructors should be able to
assess when an appropriate level of proficiency is achieved. Instructors should be trained on how to judge pilot performance on the UPRT events and determine whether the required learning
objectives have been met.
2-6. INSTRUCTOR STANDARDIZATION.
a. Initial Standardization Validation. Following completion of UPRT instructor
training, and before providing unsupervised instruction, instructors should complete an Instructor
Standardization validation to ensure readiness to provide accurate UPRT, to include evaluation of:
• UPRT knowledge and skills applicable to the UPRT for which they are being
standardized;
• Ability to teach, brief, assess, and debrief the elements included in the UPRT for which they are being standardized;
• FSTD instructor ability to effectively operate the device and all of its available de-briefing capabilities.
• Effective recognition of pilot errors, identification of root cause, and adjustments to training to correct errors and achieve the required level of proficiency;
• Assess the achievement of an appropriate level of proficiency in accordance with
the completion criteria.
Par 2 -5 Page 9
4/14/15 AC 120-111
b. Continuing Standardization. Each air carrier should have a co ntrol system in place to
ensure its instructors continuously deliver standardized UPRT. Instructors who do not follow the
curriculum may provide pilots with negative training .
Par 2 -6 Page 10
4/14/15 AC 120-111
CHAPTER 3. TRAINING METHODOLOGY
3-1. GENERAL. The training methodology for UPRT should follow the building block
approach of first introducing essential concepts and academic understanding before progressing
to the practical application of those skills in a flight simulation training device (FSTD). Similarly, familiarity with airplane characteristics and development of basic recovery skills
through maneuver-based training should precede their application in scenario-based training. This progressive approach will lead to a more complete appreciation of how to recognize a
developing flightpath divergence, respond appropriately in situations of surprise or startle, and recover effectively when required. Air carriers should develop training curriculums that provide pilots with the knowledge and skills to prevent, recognize, and recover from unexpected flightpath divergences and upset events. These training curriculums should contain the elements and events described in Appendix 1.
3-2. COMPREHENSIVE AIR CARRIER UPRT PROGRAM.
a. General. The FAA strongly recommends incorporation of the Airplane Upset Recovery
Training Aid (AURTA) into air carrier UPRT programs. The AURTA has extensive discussion
and considerations for both the academic and flight training portion of an air carrier’s training
program. The Airplane Ups et Recovery Training Aid is available online at
http://www.faa.gov/other_visit/aviation_industry/airline_operators/training/media/AP_UpsetRec
overy_Book.pdf.
b. Flight Standardization Board (FSB) Reports. When developing UPRT programs,
air carriers should consult the FSB report, if available, for the specific airplane type. The
Training Areas of Special Emphasis, and any other recommendations pertaining to in- flight
aircraft handling, should be reviewed.
c. Academic Knowledge. Academic instruction establishes the foundation from which
situational awareness, insight, knowledge, and skills are developed, and therefore must be accomplished prior to training the associated flight events in an FSTD. To ensure sufficient retention, FSTD training should occur within a rea sonable time after academic training.
Academic knowledge should proceed from the general to the specific.
d. FSTD Training. Section 121.423 requires extended envelope training, which consists
of the following maneuvers to be conducted in a Level C or higher f ull flight simulator (FFS):
manually -controlled slow flight, manually -controlled loss of reliable airspeed,
manually -controlled instrument departure and arrival, and upset recovery maneuvers. Other
flight training that is part of UPRT, but not required by regulation to be conducted in an FFS
may be conducted in another type of FSTD; however, the FSTD should have the level of fidelity required to meet the learning objective. Training providers are encouraged to use the highest level FFS available when develo ping their UPRT curriculums. The primary emphasis is to
provide the pilot with the most realistic environment possible during UPRT. Motion in an FFS should be used when those cues influence recognition or recovery.
(1) FSTD flight training should follow a logical progression where pilots are introduced
to the airplane’s capabilities within the operating limits prior to training at the edge of the normal
Par 3-1 Page 11
4/14/15 AC 120-111
flight envelope, or beyond. While exceeding the normal flight envelope in an FFS is possible, all
UPRT maneuv ers contained in this AC can typically be conducted inside the FFS’s intended
training envelope where the performance and handling qualities of the FFS are at their highest accuracy. Training that exceeds the airplane envelope or the aerodynamic modeling envelope could increase the risk of negative transfer of training. Significant sustained accelerations and rates are not possible in an FFS, and instructors should be able to explain to pilots how the actual aircraft behavior may differ. See Appendix 3 for detailed FSTD considerations.
(2) FSTD training should include both maneuver-based and scenario-based training. Air
carriers are encouraged to consult with the airplane manufacturer during the development of the FSTD training.
(a) Maneuver-Based Training. This tra ining focuses on task mastery.
Maneuver -based training should include prevention and recovery training with an emphasis on
the development of required motor skills to satisfactorily accomplish upset recovery. Limited emphasis should be placed on decisionmaking skills during maneuver-based training.
(b) Scenario -Based Training (SBT). The goal of SBT is to develop perception and
decisionmaking skills relating to upset prevention, recognition, and recovery, while providing the pilot with an opportunity to use the skills learned in maneuver- based training in a realistic
scenario. SBT would normally be used after maneuver-based training, during the later stages of an initial, transition, or upgrade training curriculum, and during recurrent training.
1. Realistic Scenarios. UPRT scenarios should be realistic events that could be
encountered in operational conditions. When possible, scenarios should include accident, incident, Aviation Safety Action Program (ASAP), Flight Operational Quality
Assurance (FOQA), and/or Aviation Safety Reporting System (ASRS) data to convey how threat situations may develop and how they should be managed. Sample SBT lesson plans are provided in Appendix 2.
2. Briefing. Pilots should not normally be briefed that they are receiving SBT.
The concept allows pilots to recognize and manage upset threats as they develop during normal operations.
3-3. KEY UPRT CONSIDERATIONS.
a. Awareness and Prevention. Training with an emphasis on awareness and prevention
provides pilots with the skills to recognize conditions that increase the likelihood of an upset
event if not effectively managed. Training must include the air carrier’s standard operating
procedures (SOP) and Crew Resource Management (CRM) techniques for the most effective prevention and threat mitigation strategies. Desired goals for awareness and prevention training
include the following:
(1) Recognition of operational and environmental conditions that increase the
likelihood of an upset event occurring;
Par 3 -2 Page 12
4/14/15 AC 120-111
(2) Aeronautical decisionmaking skills to prevent upsets (e.g., effecti ve analysis,
awareness, resource management, mitigation strategies, and breaking the error chain through
airmanship and sound judgment);
(3) Early detection of flightpath divergences;
(4) Timely and appropriate intervention;
(5) The effects of autoflight including mode confusion, flight envelope protection in
normal and degraded modes, and unexpected disconnects of the autopilot or autothrottle/autothrust;
(6) Recognition of when the flight condition has transitioned from the prevention phase
into the recovery phase; and
(7) Effective verbal and non -verbal communication regarding the airplane state.
b. Manual Flight Operations Knowledge, Skills, and Utilization. Modern aircraft are
commonly operated using autoflight systems (e.g., autopilot or autothrottle/autothrust) during most of a flight. Autoflight systems have improved safety, reduced workload, and enabled more precise operations; however, continuous use of autoflight systems could lead to degradation of the pilot’s manual handling skills and ability to recover the aircraft from an upset.
NOTE: Air carriers are encouraged to take an integrated approach by
incorporating manual flight operations into both line operations and training (initial, transition, upgrade, requalification, and recurrent).
(1) Training. Several maneuv ers are included in Appendix 1 specifically to develop
and maintain a pilot’s manual flight operations knowledge and skills.
(2) Operations. Air carriers should develop policies that encourage manual flight
operations when appropriate. Operational policies should be developed or reviewed to ensure there are appropriate opportunities for pilots to exercise manual flying skills, such as in
non-Reduced Vertical Separation Minimum airspace and during low workload conditions. In
addition, policies should be developed or reviewed to ensure that pilots understand when to use the automated systems, such as during high workload conditions or for airspace procedures that require precise operations. Augmented crew operations may also limit the ability of some pilots to obtain practice in manual flight operations. Airline operational policies should ensure that all pilots have the appropriate opportunities to exercise manual flight knowledge and skills in flight operations.
(3) Use of Autopilot and/or Autothrottle/Autothrust for Upset Recovery. Leaving
the autopilot or autothrottle/autothrust connected may result in inadvertent changes or adjustments that may not be easily recognized or appropriate, especially during high workload situations.
c. Availability of Visual References. The CAST study of 18 accidents and incidents
resulting from pilot loss of airplane state awareness determined that 17 accidents and incidents
Par 3 -3 Page 13
4/14/15 AC 120-111
occurred when pilots did not have visual references available (i.e., instrument meteorological
conditions (IMC) or night). In the past, unusual attitude training was commonly conducted in visual meteorological conditions, giving the pilot considerable advantage in determining the appropriate recovery. To develop a pilot’s ability to recover from an upset, FSTD maneuvers training should be done in both visual and instrument conditions, as well as in day and night. This allows pilots to practice recognition and recovery under all conditions in order to experience important physiological factors.
d. Pilot Monitoring. Evidence shows that in many loss of control in- flight (LOC -I)
incidents and accidents the pilot(s) monitoring (PM) may have been more aware of the airplane state than the pilot flying (PF). Training should emphasize crew interaction (including augmented flightcrews ) to vocalize a divergence from the intended flightpath. A progressive
intervention strategy is initiated by communicating a flightpath deviation (alert), then suggesting a course of action (advocacy and assertion), and then directly intervening, if necess ary, by taking
the controls to prevent an incident or accident. A pilot taking control should announce the transfer of control.
e. Startle or Surprise. Startle or surprise has been a factor in LOC -I incidents and
accidents as upsets that occur in normal operations are unplanned and inadvertent, adversely impacting recognition or recovery. Instructors should plan upset scenarios emphasizing those event conditions and variables likely to result in startle/surprise while minimizing potential for negative transfer of training. The potential for negative transfer of training can be minimized
through applying sound judgment with respect to realism and fidelity, as well as respecting the capabilities and limitations of the FSTD. The following points should be consider ed:
• Many possible events should be available for use during training. Otherwise, pilots
will anticipate the event and not be surprised.
• The events should be taught in a supportive learning environment without jeopardy. Otherwise, incentives are introduced for pilots to share with other pilots what to
expect.
• Even if incentives are not introduced, pilots should be discouraged from revealing
information about the events to other pilots that have yet to experience them.
Divulging a surprise scenario removes the benefit of allowing a colleague to
examine his or her thoughts and responses in critical situations that arise in training. As such, the strategic objective of inserting these scenarios in training should be emphasized for the benefit of all.
• Instructo rs will have to be inventive and introduce various ploys to achieve a startle
or surprise response in simulation. Managing expectations in this way can help achieve responses while surprised even in simulation environments when the fear of harm does not ex ist.

CHAPTER 4. UPSET RECOVERY TEMPLATE
4-1. METHODOLOGY. Airplane manufacturers (Airbus, ATR Aircraft, Boeing, Bombardier,
and Embraer) contributed to the development of the following upset recovery templates that
provide commonality among various airplanes.
4-2. UPSET RECOVERY TEMPLATES. Tables 1 and 2 show the Nose High and Nose Low
Upset Recovery Templates that were developed with input from the above manufacturers.
Although the procedures apply to the majority of today’s airplanes, manufacturer-recommended procedures may deviate from those included in this advisory circular (AC) due to specific airplane characteristics. Manufacturer recommendations may deviate from this template if necessary due to airplane operating characteristics. For air carriers operating airplanes without manufacturer upset recovery procedures, the FAA recommends using the upset recovery templates as a reference when developing air carrier -specific upset recovery procedures.
NOTE: The manufacturer’s procedures take precedence over the
recommendations in this AC.
NOTE: These techniques assume the airplane is not stalled. If the airplane is
stalled, recovery from the stall must be accomplished first in accordance with
the current edition of AC 120-109, Stall Prevention and Recovery Training,
or manufacturer procedures.
a. The following techniques represent a logical progression for recovering the airplane.
While not strictly procedural, the templates represent a consensus view of actions for recovery.
b. If needed, use pitch trim sparingly. Careful use of rudder to aid roll control should be
considered only if roll control is ineffective.
c. This section uses the following acronyms: AP for autopilot and A/THR for
autothrottle/autothrust.

TABLE 3. NOSE HIGH R ECOVERY TEMPLATE WIT H EXPLANATION
Either Pilot : Recognize and confirm the d eveloping situation. Announce: “Nose High”
Explanation: A critical element in recognition and confirmation is to clearly understand the
energy state and the rate to which it is changing because this will have an effect on how the
PF handles the recovery.
Pilot Flying
AP: DISCONNECT8
A/THR: OFF
Explanation: Leaving the autopilot or autothrottle/autothrust connected may result in
inadvertent changes or adjustments that may not be easily recognized or appropriate,
especially during high workload situations.
PITCH: Apply as much nose -down control input as required to obtain a nose -down pitch
rate.
Explanation: This may require as much as full nose -down input. If a sustained column force
is required to obtain the desired response, use nose-down trim as needed to counter high stick forces .
If nose-down inputs are not successful in achieving a nose-dow n pitch rate, p itch may be
controlled by rolling the airplane. A large bank angle is helpful in reducing excessively high pitch attitudes. The angle of bank should not normally exceed approximately 6 0°.
Continuous nose-down elevator pressure will keep the wing angle of attack low, which will
make the normal roll controls effective. The rolling maneuver changes the pitch rate into a
turning maneuver, allowing the pitch to decrease.
THRUST: Adjust (if required)
Explanation: Combined with pitch trim , an additional effective method for achieving a
nose-down pitch rate on airplanes with under- wing mounted engines can be to reduce the
power. Thrust should only be reduced to the point where control of the pitch is achieved. This reduces the upward pitch moment. In fact, in some situations for some airplane models, it may be necessary to reduce thrust to prevent the angle of attack from continuing to increase.
If the pitch rate is being managed by trim and elevator inputs, it is not recommended to
reduce thrust.
RECOVER to level flight9 when airspeed is sufficiently increasing:
8 A large out of trim condition could be encountered when the AP is disconnected.

A/THR: OFF
Explanation: Leaving the autopilot or autothrottle/autothrust connected may result in
inadvertent changes or adjustments that may not be easily recognized or appropriate,
especially during high workload situations.
RECOVER from stall if requi red
Explanation: Even in a nose -low, low -speed situation, the airplane may be stalled at a
relatively low pitch. It is necessary to recover from the stall first. This may require
nose-down elevator, which may not be intuitive.
ROLL11 in the shortest direc tion to wings level.
Explanation: Full aileron and spoiler input may be necessary to smoothly establish a
recovery roll rate toward the nearest horizon. It is important that positive g force not be
increased or that nose- up elevator or stabilizer trim be used until the airplane approaches
wings level. It may be necessary to unload the airplane by decreasing backpressure to
improve roll effectiveness. If the airplane has exceeded 90° of bank, it may feel like
“pushing” in order to unload. It is necessary to unload to improve roll control and to prevent
pointing a large lift vector towards the ground.
THRUST and DRAG: Adjust (if required)
Explanation: If airspeed is low, apply thrust; if airspeed is high, reduce thrust, and if
necessary, extend speedbrakes.
RECOVER to level flight.12
Explanation: Complete the recovery by establishing a pitch, thrust, and airplane drag device
configuration that corresponds to the desired airspeed.

effects of e nvironmental, airplane configuration, or system
changes on planned flight performance.
• Training pilots to understand that an airplane may not be able to reach its maximum certified altitude depending on performance at the time of the flight is critical. Pilots should also understand the possible consequences of choosing a cruising altitude that exceeds the airplane’s performance capabilities for the conditions existing
at the time of the flight.
• Recognition of the different flight deck cues between low spee d

• Importance of AOA as it relates to airplane performance and wing
stall angle
• Effect of airplane configuration (e.g., flaps, gear, leading edge
slats, speedbrakes, and thrust/power setting) on stall margins and
stall characteristics

• Critical Mach number and aerodynamic forces acting o n the wing
at critical Mach.
• Control surface effectiveness at high speed
NOTE: Training for AOA and Mach effects should
only be accomplished to the extent of their applicability
to the specific airplane.
Flight The FSTD training should be accomplished at both high altitudes (within
5,000 ft. of the service ceiling of the airplane), and low altitude (below 10,000 ft. above ground level (AGL)). Use of normal operational cruise altitudes for high -altitude training should be encouraged. To fully
understand the concepts discussed in academic training, pilots should demonstrate the following:
• Recognize buffet (if applicable to airplane type), when encountered
• Maneuvering at high altitudes at various speeds and automation
levels applying the aerodynamic principles studied to prevent an
upset
•
Awareness of the AOA from available data shown on the flight deck (e.g., barber pole on speed tape, pitch- limit-indicator,
flight- path-symbol relative to pitch attitude, etc.) and demonstrate
the use of those data to prevent an upset or recover from one

Additional details regarding these areas can be found in the Airplane
Upset Recovery Training Aid Revision 2 (AURTA), section 2.5. While the AURTA was designed for swept -wing airplanes with more than
100 seats, the general concepts are still applicable to most
high-performance airplanes.
2. G Awareness
Academic The effects of g’s, especially during airplane upsets. Emphasize that
g-loading in transport category airplanes feels significantly more
pronounced than in simulation. Airline pilots are normally uncomfortable (for the sake of passenger comfort and safety) with aggressively loading
or unloading the g forces on a large passenger airplane. This inhibition must be overcome when faced with the necessity to quickly and
sometimes aggressively maneuver the airplane. Most FFSs cannot
replicate sustained load factors greater or less than 1g; therefore, the flight deck situation must be envisioned during flight different from 1g . The
pilot may feel significantly heavier or lighter in the seat for moderate
durations . It may be difficult to reach the rudder pedals. Unsecured items
may be flying around the flight deck . However, it should be emphasized
that it should not normally be necessary to maneuver at less than 0g.
Flight Incorporated into section 8 Upset Recovery Techniques below.
3. Energy Management
Academic • The interrelationship between kinetic energy (airspeed), potential
energy (altitude), and chemical energy (power)
• How the airplane gets in a high -or low -energy state and the input
options available to change the energy state to a stable and safe state
• How external factors can change energy state and how to correct
for them
Page 3
4/14/15 AC 120-111
Appendix 1
• What parameters to focus on to decide an appropriate response;
crosscheck with the other pilot to establish a shared understanding
• What to monitor during an event and how the pilot
monitoring (PM) should assist the pilot flying (PF) in the recovery
using appropriate cal louts and other verbal feedback
Flight This training should include integrat ed Crew Resource
Management (CRM) training for developing crew knowledge and skills
for energy management and techniques for reducing pilot error. To fully understand the concepts discussed in academic training, pilots should demonstrate the following:
• Acceleration between two speeds of which the airplane is capable
at low altitude, medium, and high altitude (e.g., accelerating
between 200 and 250 knots at low altitude and high altitude ,
which
corresponds to Mach changes at high altitude) to demonstrate
changes in available thrust
• Acceleration performance from region of reversed command (back
side of power curve) at low altitude and high altitude
• The relationship between Maximum Cruise/Climb/Continuous
Thrust and takeoff/go-around (TOGA) power settings at hi gh
altitude
• Acceleration capabilities through descent versus power application
• Wake vortex encounter behind a heavy airplane in takeoff and
approach configuration
4. Flight path Management
Academic Flightpath and energy management systems: Pilots should have a
thorough understanding of the normal operation, failure modes and
effects, and system integration effects of flightpath and energy
management systems. Training on flightpath and energy management systems should include:
• Normal system operation and l imitations
• Indications and modes, including crosscheck and verification of
mode use and understanding of how a specific mode will
command the airplane; interoperability with other systems
• Failure modes and effects
• Common model- specific failures
• Common errors to avoid and why they occur
• The importance of ensuring correct inputs to the automat ed
systems for flightpath management and the consequences of
failing to do so
• Understanding of type- specific characteristics to prevent
inadvertent LOC -I events because of automation surprise
(e.g., vertical speed (VS) or indicated airspeed (IAS) modes based
on altitude)
Page 4
4/14/15 AC 120-111
Appendix 1
• System review when conducting recurrent training
• Knowledge of pitch attitudes, power settings, and airspeeds for
common configurations and different phas es of flight , as
applicable to the airplane type.
Manual Flight Operations:
• Primary and alternate control strategies
• Non-intuitive factors. For example, it may be counter -intuitive to
use greater unloading control forces when recovering from a high
AOA, es pecially at low altitudes
• Additionally, for under- wing mounted engines it may be necessary
to reduce thrust in order to reduce the AOA due to the strong pitch up forces from added thrust.
• Specific aspects of the transition from automated to manual flight
including transition from using a flight director to “raw data,” as
applicable .
Flight Training should include abnormal operating conditions, reliance on
primary flight instruments, manual flying skills, and edge-of- envelope
operating conditions that could be encountered during routine operations.
Examples include:
• Takeoff at high weight and aft/forward CG limits
• Recognition and recovery from low-airspeed/energy condition in
approach/landing configuration
• Recognition and recovery from low- airspeed/energy co ndition
near the service ceiling
• Climb -to, steady state, and descent from service ceiling
• Unplanned transition from automated to manual flight, including
transition from using a flight director to “raw data,” as applicable.
5. Causes and Contributing Fact ors of Upsets
Academic • Environmentally induced upsets, which could be caused by
turbulence, mountain wave, wind shear, thunderstorms,
microbursts, or airplane icing.
• Pilot- induced upsets which could be caused by misinterpretation or
slow instrument crosscheck, improper adjustment of attitude and
power, improper pilot input, inattention, distractions, spatial
disorientation, pilot incapacitation, misunderstanding of autoflight modes or improper use of automated systems, transition from automated to manual modes due to system disconnect, and pilot-induced oscillation (PIO).
• Mechanically -induced upsets that could be caused by flight
instrument anomalies/failures, autoflight anomalies/failures, flight control malfunctions/failures, or other system anomalies .
• Common illusions (e.g., somatogravic illusion, the leans, Coriolis
illusion, etc.) associated with LOC -I events. It should be explained
Page 5
4/14/15 AC 120-111
Appendix 1
why they occur and the importance of fo llowing procedure to
avoid susceptibility to illusions.
• Situations resulting in an upset due to a lack of visual cues such as
a sub -threshold roll (i.e., imperceptible roll rate, generally less
than three degrees per second).

6. Review of Accidents and Incidents Relating to Airplane Upsets
Academic Review of accidents and incidents related to transport category airplane
upsets with focus on an understanding of the events leading to the upset,
proper or improper decisionmaking actions that contributed to the upset, and, if applicable, recovery. Aviation Safety Action Program (ASAP),
Flight Operational Quality Assurance (FOQA), and Aviation Safety
Reporting System (ASRS) data can also support this discussion.
Flight Not applica ble
7. Recognition
Academic a. Type -specific examples of instrument indications during
developing and developed upset.
• Visual representations of the outside view and type- specific
instrument indications of a variety of developing and developed upset conditions, with a focus on pitch, power, roll, and speed trend. Pilots should be provided context for each event in order for them to identify the divergence.
• Some normal situations should also be included so pilots can
identify what is normal versus what is not.
• If applicable, discuss other cues, such as audio or buffet cues.
b. Pitch/Power/Roll/Yaw
• Pilots must have a fundamental understanding of instrumentation
and flight dynamics in pitch, power, roll, and yaw in order to recognize the current state of the airplane and make the correct control inputs to arrest the divergence or recover from the upset.
• The use of the AURTA, Revision 2, section 2.5.5.5–
section 2.5.5.9
is recommended for specific details for training Pitch/Power/Roll/Yaw.
c. Effective Scann ing
• Effective instrument scanning techniques should be trained, as
appropriate, to recognize normal states and divergence from
normal flight parameters.
• To prevent flightpath divergences related to improper monitoring
of airplane state, pilots should be trained during all phases of flight
on what to monitor and when, crosschecking, and verification.
Page 6
4/14/15 AC 120-111
Appendix 1
d. CRM techniques for working as a crew to return the airplane to
normal flight and communicating airplane state between pilots, including
CRM callouts to impro ve situational awareness.
• Evidence shows that the PM is often in a better position to
recognize adverse trends in airplane state or flight parameters than
the pilot flying (PF).
• The PM should be tasked with active monitoring of aircraft state
and flight parameters and prompt callout of any divergence from
planned and/or briefed flightpath.
Flight The academic principles of recognition should be continuously reinforced
by the ins tructor during flight training.
8. Upset Recovery Techniques
Academic • Emphasize timely and appropriate intervention.
• Emphasize that recovery to a stabilized flightpath should be
initiated as soon as a divergence from intended flightpath is
recognized.
• Emphasize the need for the PF or PM to recognize a divergence as
early as possible, and immediately ensure corrective action is
taken to return the airplane to a stabilized flightpath rather than waiting until the airplane has developed into an established upset.
• The use of an intervention strategy employed by the PM that
progresses from alerting the PF of a divergence from the intended
flightpath, to suggesting a course of action (advocacy and assertion), and proceeds to directly intervening by taking the controls to prevent an accident or incident. In the event that a pilot intervenes by taking control of the airplane, he should announce the transfer of control.
• The attitude direction indicator (ADI) , attitude display of the
primary flight display (PFD), or head -up display (HUD), as
applicable, is the primary control instrument for recovery from an
upset.
• Due to varying visibility conditions, pilots cannot depend on having adequate outside visual references.
• Air carriers and Original Equipment Manufacturers (OEM) may
already have policies on how to handle minor divergence from the desired flightpath for items such as bank, airspeed, heading, etc., including callouts. The intent of these procedures or CRM techniques is for the PM to draw attention to any divergence that exceeds parameters set by the company and for the PF to take corrective action.
• Control inputs to counter a developing upset must be smooth,
positive, and proportional to the amount and rate of pitch, roll, or
yaw experienced.
Page 7
4/14/15 AC 120-111
Appendix 1
• Up to full -scale control deflections may be necessary; however,
initiating recovery with arbitrary full- scale control deflections
could aggravate the situation. An aircraft’s response to excessive
or inappropriate control input that overshoots the desired response can startle or surprise the pilot and cause one upset to lead to another.
The use of the AURTA, Revision 2, sections 2.6.3.2–2.6.3.5, is recommended for details to train the academic portion of the recovery techniques for the four elements below. For instructional purposes, the AURTA, Revision 2 addresses several different airpl ane upset situations
(listed below). This provides the basis for relating the aerodynamic information and techniques to specific situations.
• Nose -High/Wings -level recovery
• Nose -Low/Wings- level recovery
• High Bank- Angle Recovery Techniques
• Consolidated Summa ry of Airplane Recovery Techniques
Flight The nose -high and nose -low maneuvers in Chapter 4, Tables 1 and 2,
should be practiced first in maneuver-based training, followed by Scenario -Based Training (SBT). For the recovery from the nose-high
upset, pilots are instructed to push to achieve less than 1g .
NOTE: Rudder control is still effective at a high AOA,
and special care must be taken in the use of rudder during upset prevention and recovery. It is important to guard against control reversals. To maintain structural integrity, avoid rapid full- scale reversal of
control deflections.
During this training, the instructor should:
• Use the Instructor Operating Station (IOS) to track g -load and
other flight parameters during recovery ;
• Provide specific feedback if reco very was too aggressive,
i.e., structural or other flight limits were exceeded during recovery;
• Provide specific feedback if recovery was insufficiently positive,
i.e., recovery was delayed or impaired due to insufficient control
inputs;
• Provide specific feedback if recovery control inputs were
excessive, or cyclic with control reversals; and
• After the pilot uses the correct amount of force to recover, note
that the absence of g -load sensing in the FSTD may lead to a
tendency to undercontrol recovery in the actual aircraft when these
loads are sensed.
9. Specialized Flight Training Elements for Upset Prevention
Page 8
4/14/15 AC 120-111
Appendix 1
Flight Sections 121.424 and 121.427 require initial, transition, upgrade, and
recurrent training to include the extended envelope training in § 121.423.
Each maneuver or procedure listed below is required by § 121.423, except steep turns, which are required by part 121 appendix E, and teaches a specific skill-set to help pilots build their manual handling skills and prevent upsets.
• Manually -
controlled slow flight: The target speed for slow flight is
VREF, as calculated, for the configuration. Slow flight exposes the
pilot to flight just above the stall speed and how to maneuver the airplane at this speed , in situations other than an approach, without
stalling. The purpose is to reinforce the basic stall characteristics learned in academics and allow the pilot to obtain handling experience and motion sensations when operating the airplane at slow speeds in the impending regime in various airplane attitudes, configurations, bank angles, and altitudes, including high altitudes.
• Steep turns: Steep turns provide the pilot with some practical experience of the consequences of load factor and maneuvering the airplane at higher than normal bank angles.
• Manually -controlled loss of reliable airspeed (See Appendix 2,
Scenario 2) : The training of an airspeed indication system
malfunction is critical for a pilot’s understanding of type specific failure modes. Additionally, cascading failure of other dependent systems provides a training environment, which allows a pilot to practice manually handling an aircraft with varying degrees of automation and capabilities that may be present during upset. In
many instances, the loss of reliable airspeed results in an aircraft which must be flown primarily by relying on pitch and power. Further, these maneuvers require an understanding of the aerodynamic qualities of large transport category aircraft.
• Manually -controlled instrument departure and arrival: Modern
aircraft are commonly operated using autoflight systems (e.g., autopilot or autothrottle/autothrust). Autoflight systems are useful tools and have improved safety and workload management, and thus enable more precise operations; however, continuous use of
autoflight systems could lead to degradation of the pilot’s ability to
quickly recover the aircraft from an undesired state.
10. System Malfun ctions
Academic • Understanding of airplane systems and how system malfunctions
can contribute to an upset.
• Air carriers should refer to OEM checklists and procedures, which
cover system and component failures.
• Review additional information from the AURTA, Revision 2,
section 2.4.2.

Appendix 1
Flight System malfunctions can contribute to an upset. FSTDs allow instructors
to safely induce malfunctions that would not be possible in the airplane.
Failures/malfunctions related to systems, instruments, power, and automatio n should all be incorporated into training, whenever applicable.
Inaccurate information, if possible, should also be part of the training program (e.g., unreliable airspeed), so pilots learn to recognize the error,
prevent an upset, and maintain control of the airplane.
11. Normal and Degraded Modes for Envelope Protec ted Airplanes
Academic • Understanding of normal modes of envelope protection, as well as
all possible degraded modes of envelope protection.
• Comprehensive information regarding envelope protection is
available from the aircraft manufacturer.
• Air carriers must adequately train pilots on the varied effects of
envelope-protection during normal, abnormal, and emergency
situations. For part 121 operations, the requirements are listed
under § 121.419(a)(2)(v), § 121.427, part 121 appendix E,
appendix F, and § 121.913 for Advanced Qualification Programs (AQP).
• Consideration of the Flight Standardization Board (FSB) Report is
recommended. This report may contain additional training
requirements, s pecific to aircraft type, not contained in the CFRs
or manufacturer documentation.
Flight Demonstrate flight envelope protection in normal and degraded modes.
Highlight the differences in symbology, instrumentation, and flight
characteristics, as appropri ate.

APPENDIX 2. SAMPLE TRAINING SCENARIOS AND MANEUVERS
Three scenarios were constructed using the philosophies and concepts described in this advisory
circular (AC). Training providers are encouraged to develop additional scenarios that fit their training needs. The examples should be easily tailored to any transport category airplane. The examples given are not intended to be limiting; they are provided as a framework for developing a training curriculum.
NOTE: The manufacturer’s procedures take precedence over the
recommendations in this AC.
EXAMPLES OF SCENARIOS AND MANEUVERS FOR UPSET PREVENTION AND
RECOVERY TRAINING
SCEN ARIO 1: NOSE -HIGH ATTITUDE IN AN AIRPLANE WITH
UNDER -WING MOUNTED ENGINES
INSTRUCTOR ROLE Implement scenarios that result in an unexpected
nose-high attitude (40° or greater) with full power.
OBJECTIVE This scenario is ONLY for airplanes with under -wing
mounted engines. The pilot will recognize the nose- high attitude and immediately perform the upset
recovery procedure. If a detectable nose-down pitch
rate is not initially achievable, the pilot should demonstrate recovery by reducing the thrust to a point
where a nose -down pitch rate is achieved .
EMPHASIS AREAS • Effect of thrust on pitch moment.
• Recognition and recovery.
• Crew coordination.
• Angle of attack (AOA) management , including
available AOA indicati ons.
• Aural and visual warnings (environment and
airplane cu eing).
• Surprise and startle.
• Situational awareness (SA) while returning to desired flightpath after the upset recovery,
including such items as heading, altitude, other
aircraft, and flight deck au tomation.
FSTD SETUP
CONSIDERATIONS In order to create potential onset conditions, consider
use of the following:
• System malfunctions resulting in erroneous
pitch attitude indications;
• Other system malfunctions resulting in a nose
high attitude;
Page 1

Appendix 2
SCEN ARIO 1: NOSE -HIGH ATTITUDE IN AN AIRPLANE WITH
UNDER -WING MOUNTED ENGINES
• Realistic environmental threats destabilizing the
flightpath.
SCENARIO ELEMENTS • Upon recognizing the first indication of an
upset, perform the upset recovery procedure.
• The necessity for smooth, deliberate, and
positive control inputs to avoid increasing load factors.
• Reducing thrust , if necessary, can reduce the
upward pitch moment.
COMPLETION STANDARDS • Recognizes and confirms the situation.
• Initiates recovery by reducing thrust to approximately midrange until a detectable nose-down pitch rate is achieved.
• Verifies the autopilot and autothrottle/autothrust
are disconnected.
• Proper recovery consists of up to full nose- down elevator and by using stabilizer trim,
if required. A steady nose-down pitch rate
should be achieved and it should be noted that the airpl ane would be less than 1g and the
associated characteristics of such.
• When approaching the horizon the pilot checks
airspeed, adjusts thrust, and establishes the
appropriate pitch attitude and stabilizer trim setting for level flight.
• The maneuver is considered complete once a
safe speed is achieved and the airplane stabilized.
• Satisfactory crew coordination must be
demonstrated.
COMMON PILOT ERRORS • Fails to disengage the autopilot and autothrottle.
• Fails to reduce thrust sufficiently , if necessary,
to obtain nose-down pitch.
• Reduces thrust excessively.
• Fails to use sufficient elevator authority
• Fails to use stabilizer trim when necessary
COMMON INSTRUCTOR • Fails to notice improper control inputs.
ERRORS • If the FSTD training envelope was exceeded,
fails to advise the pilot to p revent negative
training .

CONSIDERATIONS operating altitude in instrument meteorological conditions (IMC). Use of flight simulation training device (FSTD) capabilities to induce erroneous airspeed indications may include:
• Full or partial pitot/static blockage or icing.
• Air data computer failures.
SCENARIO ELEMENTS • During cruise, one or two airspeed indicators
will malfunction.
• The pilot recognizing the erroneous airspeed
data indication will verbally announce the
discrepancy.

SCENARIO 3: SUB -THRESHOLD ROLL
INSTRUCTOR ROLE Implement scenarios that cause an imperceptibly slow
roll rate (less than 3° per second) that result in an
unexpected high bank angle .
OBJECTIVE The pilot will recognize the high bank angle and
immediately perform the upset recovery procedure.
EMPHASIS AREAS • Recognition and recovery.

• SA while returning to desired flightpath after
the upset recovery, including such items as
heading, terrain, altitude, other aircraft, and
flight deck automation.
FSTD SETUP
CONSIDERATIONS The scenario will be conducted at an altitude that will
allow for a recovery. Crew distractions may be used (e.g., minor malfunctions, air traffic control (ATC)
instructions, weather). Use of FSTD capabilities to induce a slow, imperceptible roll rate (less than 3° per second) may include:
• Attitude changes,
• Thrust asymmetry,
• System malfunctions (e.g., surreptitious
disabling of automation).
• Dynamic upsets should not be implemented in a manner that disables or unrealistically reduces
flight control effectiveness for the purpose of
generating or attaining an upset condition.

causes the airplane to enter an imperceptible roll resulting in an unexpected bank angle grea ter
than 30°.
• Either pilot will notice and announce the
excessive bank.
• The pilot flying will demonstrate the proper recovery procedure.
• Disengage the autopilot and autothrottle.

Appendix 2
SCENARIO 3: SUB -THRESHOLD ROLL
• If a nose high or nose low condition exists,
identify the situation and apply the correct
recovery .
• Maintain awareness of energy management and
airplane roll rate.
• Unload (reduce AOA) as necessary and roll to wings level as the nose approaches the horizon.
Recover to a slightly nose-low attitude. Check airspeed and adjust thrust and pitch as necessary.
• When recovery is assured, adjust the pitch
attitude to return to the intended flightpath.

demonstrated.
COMMON PILOT ERRORS • Recovery is initiated by rolling in the wrong
direction, increasing the bank.
• Losing situational awareness and failing to
return to assigned flightpath or follow ATC
instructions after recovery.
• Pilot(s) slow to recognize or announce the
excessive bank.
• Executes improper recovery procedure.
• Failure to disengage the autopilot and/or
autothrottle/autothrust.
• Slow to reduce angle of attack (unload).
• Failure to maintain awareness of energy
management .
COMMON INSTRUCTOR
ERRORS • Fails to notice improper control inputs.
• If the FSTD training envelope was exceeded,
fails to advise the pilot and stop the scenario to
prevent negative training.

Appendix 2
MANEUVER 1: MANUALLY -CONTROLLED SLOW FLIGHT
OBJECTIVE Recognize the low energy or high drag configuration
and the slow response to flight control and thrust inputs
to enhance the pilot’s knowledge of the low speed
handling qualities prior to stall training.
EMPHASIS AREAS Manual flying skills
FSTD SETUP
CONSIDERATIONS • Select ceiling and visibility unlimited.
• The maneuver will be conducted in the
following two scenarios:
o Low altitude beginning in a clean
configuration, and then slowing while configuring the airplane for landing. This maneuver will be conducted at maximum landing gross weight while maintaining speed at the V
REF for the
configuration.
o High altitude in a clean configuration (e.g., near the service ceiling), near
maximum gross weight while maintaining minimum speed for the configuration.
• Target speeds must be below the speeds that are
normal and appropriate for the various
configurations. The minimum speed must avoid stick shaker. Ideally a single speed can be selected for use throughout the maneuver that will permit judicious maneuvering without stick shaker. Encountering stick shaker without executing a stall recovery could lead to negative
training.
SCENARIO ELEMENTS • While maintaining altitude, slowly establish the
pitch attitude (using trim or elevator or stabilizer), bank angle, and power setting that will allow a controlled speed reduction to establish the desired target airspeed.
• Maneuver in straight and level flight to stabilize
speed and trim.
• Turn left and right, and change direction of turn, to observe changing handling characteristics.
• Turns through 90º left and right, at bank angles appropriate to speed and configuration.
• Climb and descend at 500 feet per minute (fpm)
while in a turn.

Appendix 2
MANEUVER 1: MANUALLY -CONTROLLED SLOW FLIGHT
COMPLETION STANDARDS • Recover to appropriate airspeed for the
configuration and establish the appropriate
altitud e and heading.
• Recovery is complete when straight and level
un-accelerated flight is achieved.
COMMON PILOT ERRORS • Inadequate back -elevator pressure as power is
reduced, resulting in altitude loss.
• Excessive back -elevator pressure as power is
reduced, res ulting in a climb, followed by a
rapid reduction in airspeed and “mushing.”
• Inadequate compensation for adverse yaw
during turns.
• Fixation on the airspeed indicator.
• Failure to anticipate changes in lift as flaps are extended or retracted.
• Inadequate power management.
• Inability to adequately divide attention between
airplane control and orientation.

APPENDIX 3. FLIGHT SIMULATION TRAINING DEVICE (FSTD)
CONSIDERATIONS
1. SUMMARY OF FSTD CAPABILITIES.
a. FSTDs are a key element of a pilot training program, because they are a cost -effective
and safe alternative to performing training in the actual airplane while providing the capability to
train certain tasks which cannot be easily trained in the actual airplane. Abnormal and emergency procedures that could not be trained in the actual airplane can be trained in an FSTD, in a risk-free environment, with an adequate level of fidelity when operated within its training limits.
b. An FSTD is a synthetic environment, which cannot fully replicate the exact experience
of an aircraft; however, there is reason to be confident that the appropriately qualified FSTD has satisfactory fidelity for training normal, abnormal, and emergency procedures. In consideration of the normal limitations of FSTDs (such as aerodynamic validation, and motion cueing limitations), there is concern that practicing upset recovery techniques could include inadvertent excursions beyond its intended training envelope. This concern may be overcome if instructors have a better understanding of the FSTD limitations and additional instructor tools, which is why this advisory circular (AC) puts special emphasis on instructor training and qualification.
2. FSTD EVALUATION RECOMMENDATIONS.
a. While changes to the FSTD qualification standards are currently being developed
13 ,
they are outside the scope of this AC. It is highly recommended that all FSTDs being used for
Upset Prevention and Recovery (UPRT) maneuvers be specifically evaluated for such
maneuvers.
b. The National Simulator Program (NSP) currently maintains guidance for the evaluation
of FSTDs for use in UPRT in Guidance Bulletin 11-05, FSTD Evaluation Recommendations for Upset Recovery Training Maneuvers. NSP guidance bulletins may be found on the FAA’s public Internet site at: http://www.faa.gov/about/initiatives/nsp/.
3. INSTRUCTOR TOOLS FOR UPRT. To support UPRT in an FSTD, additional tools and
capabilities should be made available to the instructor for briefing, training, and debriefing
UPRT maneuvers. This may include video and audio capability, preprogramed distractors/initiators, as well as feedback tools to determine if the recovery maneuver has exceeded FSTD limits or airplane operational limits.
a. A set of sim ple instructor controls which can aid the instructor in developing
distractors. The distraction should be a nonstandard event such that the crew thought process and the actions they take are not based on the use of the checklist. These may be weather -related,
traffic, air traffic control (ATC), or other such inputs which may create a distraction.
13 Refer to the Notice of Proposed Rulemaking (NPRM) “Flight Simulation Training Device Qualification Standards
for Extended Envelope and Adverse Weather Event Training” (RIN 2120 -AK08) 79 FR 39461 (July 10, 2014).
Page 1
4/14/15 AC 120-111
Appendix 3
b. A dynamic set of upsets, which may be a result of internal or external factors. The
intentional degradation of FSTD functionality (such as degrading flight cont rol effectiveness) to
drive an airplane upset is generally not acceptable unless used purely as a tool for repositioning
the FSTD with the pilot out of the loop. Aircraft system malfunctions or other malfunctions may be utilized to stimulate an aircraft up set, however the effects of these malfunctions must be
representative of the aircraft and, where possible, supported by data.
• A set of upset initiation features (e.g., autothrottle/autothrust disconnection not
commanded by the pilot) designed to assess the prevention of an upset event by the crew. The objective of this upset feature is to generate a condition that, if the crew does not recognize it and take timely corrective action, it will continue to develop and result in an upset.
• A set of upset initiation features (e.g., subthreshold roll) designed to lead the crew to
initiate recognition measures. The objective of this upset feature is to generate a developing upset condition so that crew action will prevent a fully developed upset condition.
• A set of u pset initiation features (e.g., a full pitch up using external stimuli)
designed specifically to progress in severity so that the crew has to initiate recovery measures. The objective of this upset feature is to generate a developed upset condition so that the crew has to initiate appropriate recovery action to prevent further loss of control.
c. Instructor feedback tools should be provided which indicate if airplane operating limits
are exceeded, the parameters monitored may include the following:
• Airspeed limitations,
• Maximum operating speed,
• Maneuvering speed,
• Flap extended speed,
• Minimum control speed,
• Landing gear speeds,
• Rough air speed,
• Altitude limitations,
• Power plant limitations, and
• Maneuvering flight load factors including simultaneous roll and pitch.
d. The instructor should be provided with an indication of when the FSTD has exceeded
the validation limits of its aerodynamic model. The model limits may be based upon an angle of
attack and sideslip range as defined by the FSTD’s aerodynamic model provider. Refer to Appendix 3-D of the Airplane Upset Recovery Training Aid (AURTA) and NSP Guidance Bulletin #11-05 for additional information.
Page 2
4/14/15 AC 120-111
Appendix 3
e. The instructor should be provided with an indication of when an airplane limit is:
• Approached (cautionary warning—amber) or reasonable margins as appropriate can
be used; the intent is to give the instructor an initial indication that the airplane is
operating close to a limit.
• Exceeded (exceedance warning —red). The simulation should not automatically
freeze unless the limit is exceeded by a predefined margin that voids the training or can cause an unsafe condition on the FSTD.
f. The dividing line between a valid and invalid training envelope may be grey instead of
being represented by a clear line on an instructor’s display. While an instructor may adopt a conservative approach by repeating a maneuver that caused the FSTD to exceed its training envelope slightly, it is more importa nt for both the instructor and trainee to recognize that the
objective is not to convey the precise aircraft response but to reinforce the proper recovery technique. The actual response of the aircraft may vary whether inside or outside the intended training envelope. Ultimately, sound judgment is required on the part of the instructor, which can best be applied through an adequate understanding of an FSTD’s limitations.
4. FSTD MOTION LIMITATIONS.
Pilot control inputs are often highly influenced by load factor, or g. Unfortunately, a pilot in a
typical FSTD feels less than 10 percent of the actual airplane g. Both the instructor and trainee need to be aware of this difference between flight and simulation. Upset recoveries in an FSTD at high altitudes can b e prone to oscillations that go unnoticed if the full suite of available pilot
and instructor displays are not used. As such, it is important for the instructor to be alert for such problematic recoveries, convey the errors appropriately to the trainee if they occur, and repeat
the maneuvers until the trainee is proficient.
