Pilots learn the proper definition—AOA is the angle between the chord line of the wing and the relative wind—and answers to questions we’re likely to find on FAA knowledge tests: An airfoil always stalls at the same critical AOA, and an airplane can stall at any airspeed and any attitude. But few light GA aircraft are equipped with instrumentation that can show AOA in real time, so the subject is relegated to academic discussions of aerodynamic theory that seem far removed from the ways we actually fly. Today, however, lightweight, digital, and relatively inexpensive AOA instruments provide pilots of some light piston aircraft the same safety benefits that previously were limited to high-end corporate jets and U.S. Navy and Marine aircraft.
