- FOI (Fundamentals of Instruction)The body of knowledge covering the learning process, teaching methods, assessment techniques, and human behavior that flight instructor candidates must master. The FOI written test is required for all initial CFI applicants.
- Forced LandingAn unscheduled landing when continued flight is no longer possible or safe, typically after an engine failure or similar emergency. Pilots brief forced-landing options along the route—especially near high terrain or remote airports—so a suitable field or airport remains available if power is lost.
- Full-Stop LandingA landing in which the aircraft comes to a complete stop on the runway before taxiing clear or taking off again. Night passenger currency (14 CFR 61.57(b)), private pilot night training (10 full-stop landings under 61.109), and the solo towered-airport landing requirement specifically call for full-stop landings rather than touch-and-goes.
- G-AIRMETA graphical AIRMET product that depicts en route weather hazards such as turbulence, icing, mountain obscuration, and IFR conditions. Modern preflight briefings commonly present G-AIRMETs alongside SIGMETs and convective SIGMETs when building a route weather picture.
