E6B Flight Computer
The E6B — the whole flight computer
The classic flight computer, digital: the wind triangle, true airspeed, density altitude, time–speed–distance, fuel, and the unit conversions — each on its own tab.
A study aid using ISA standard-atmosphere formulae. For flight planning
use your aircraft's AFM/POH and the operator's tools — this is for learning and
quick checks.
These numbers are a study aid — the operating rules and limits themselves live in GACAR Part 91 →.
