Requirements established for control about each of 3 axes became more restrictive when simultaneous control about 2 axes at time was evaluated; for VTOL aircraft in hovering flight, there was good correlation of 2 axes requirements with flight determined pilot ratings of controllability; gyroscopic coupling between pitch and yaw axes reduced controllability.
