Federal Aviation Administration.
Inaccurate visual information for aligning the aircraft, caused by various natural and geometric formations that disorient the pilot from the actual horizon.
See flight director indicator.
Class E airspace areas that extend upward from 1,200 feet to, but not including, 18,000 feet MSL, unless otherwise specified.
Staring at a single instrument, thereby interrupting the cross-check process.
A fixed, nozzle shaped opening near the leading edge of a wing that ducts air onto the top surface of the wing. Its purpose is to increase lift at higher angles of attack.
Propellers with fixed blade angles. Fixed-pitch propellers are designed as climb propellers, cruise propellers, or standard propellers.
See flight level.
Hinged portion of the trailing edge between the ailerons and fuselage. In some aircraft ailerons and flaps are interconnected to produce full-span “flaperons.” In either case, flaps change the lift and drag on the wing.
Adjusting the aircraft control surfaces (including flaps and landing gear) in a manner that will achieve a specified attitude.
One of the major components of a flight director system, it provides steering commands that the pilot (or the autopilot, if coupled) follows.
A measure of altitude (in hundreds of feet) used by aircraft flying above 18,000 feet with the altimeter set at 29.92 “Hg.
Provides pilot and crew with highly accurate and automatic long-range navigation capability, blending available inputs from long- and short-range sensors.
The line, course, or track along which an aircraft is flying or is intended to be flown.
