FIXED-BASE SIMULATOR INVESTIGATION OF THE EFFECTS OF L ALPHA AND TRUE SPEED ON PILOT OPINION OF LONGITUDINAL FLYING QUALITIES

Abstract

The study is directed toward investigating the effects on pilots rating of large variations (L alpha) in the relative amplitude and phase of the basic airplane responses to elevator control. The effects of L alpha and true speed on longitudinal flying qualities, optimum control gain, and normal acceleration response to turbulence were investigated in a ground simulator. The steady state ratio of normal acceleration to angle of attack was found to be of significance both to the flying qualities of an airplane and to the optimum longitudinal control gain. Normal acceleration response to rough air was demonstrated to be primarily a function of L alpha and the short period frequency and damping ratio.
