Abstract:

The results of a flight research program to evaluate the effects of certain lateral-directional handling qualities are reported and discussed. The evaluation program was designed to assess the acceptability of variations in Dutch roll dynamics and aileron-yaw coupling for the low speed landing approach task. The effects of a reduction in static directional stability on the high Mach number cruise task were also evaluated. A variable stability T-33 was used for conducting these evaluations. Thirty-three different sets of low speed, and fifteen different sets of high speed lateral-directional handling qualities were evaluated by an experimental test pilot. The evaluation pilot comments and a numerical rating were given for each configuration as to its suitability for the mission or task involved. Identification of the stability parameters from in-flight records was made using airplane rudder doublet responses and the Equations-of-motion Technique. An analysis was made of the pilot ratings and pilot comments, and these in turn were correlated with the lateral-directional stability parameters measured. Author
