In order to provide information relative to the effects of gyroscopic cross coupling between pitch and roll on the handling qualities of VTOL aircraft, a flight investigation has been conducted during which cross coupling was simulated. Generality is achieved by presenting the results of the flight investigation in the form of a criterion which may be used t o predict the acceptability of the level of cross coupling in VTOL aircraft as a function of the aircraft design parameters. The criterion is based on pilot's opinions of the acceptability of the motions for the range of cross coupling which was simulated during a maneuver in which cross coupling is particularly objectionable. is used to provide a basis for application of the criterion. The theory which i s developed is shown to predict accurately the aircraft motions.
