A preliminary evaluation of the Navion as a lateral-directional flight simulator for use in the investigation of flying qualities criteria

Abstract

A preliminary evaluation was made of a modified North American NAvion airplane for use as a lateral -directional flight simulator in the investigation of flying qualities criteria. Modification of the test airplane was accomplished by installation of a three axis, variable feedback autopilot and associated controls and sensing transducers. An analytical development, based on servo-analysis methods, suggested the ratio of the numerator and denominator frequency terms in the roll angle to aileron control deflection transfer function as a possible flying qualities criterion.
