Abstract:
Effects of speed stability and turbulence upon airspeed response of an aircraft flying under landing approach conditions are investigated by considering response to turbulence when the aircraft is constrained to fly along a straight flight path by means of the elevator. The speed-stable and speed-unstable cases are treated in a uniform manner by considering the way in which airspeed 'diffuses' from an initial known value, results being expressed in terms of the time variation of the probability distribution of airspeed error.
