08 Aircraft Stability and Control

Includes flight dynamics, aircraft handling qualities, piloting, flight controls, and autopilots. For related information see also 05 Aircraft Design, Testing and Performance; and 06 Avionics and Aircraft Instrumentation.

Definition

Aircraft Stability – The property of an aircraft to maintain its attitude or to resist displacement, and if displaced, to develop forces and moments tending to restore the original condition. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.

Aircraft Control – To direct the movements of an aircraft with particular reference to changes in attitude and speed. Adapted from the Dictionary of Technical Terms for Aerospace Use. Wm. H. Allen, ed., 1965. NASA SP-7.

NASA Interest

Exhaustive Interest : Research, development, testing, evaluation, or performance topics related to the stability and control of any complete aircraft, or the interaction between the vehicle's components and the control of the aircraft in flight.

Selective Interest : Piloting as it affects the stability, control, and maneuverability of an aircraft.
