Abstract : An experimental and theoretical investigation indicates the extent to which the amount of cross coupling present in an aircraft is dependent on the angular-velocity damping and moments of inertia of the aircraft as well as the angular momentum of the engine. The amount of cross coupling which the pilot can tolerate is a function of the maneuvers encountered and the aircraft control power. A criterion based on pilots' opinions obtained from the simulation flights provides a means for determining the acceptability of cross coupling in VTOL aircraft as a function of the aircraft design parameters.
