The handling qualities of a helicopter in the hover/low speed range were investigated with a lateral tracking task. The desired behaviour of decoupled rate command/attitude hold and attitude command systems were programmed in conceptual models with numerous sets of bandwidth/phase delay configurations. In a first step, the task was flown in a fixed base simulator. Then selected configurations were investigated in flight on a helicopter in-flight simulator. In the ground simulator, the pilots clearly preferred attitude command systems. In the flight tests, none of the attitude command systems was rated Level 1. For rate command/attitude hold systems, the configurations were rated with Level 1 and Level 2 with a clear boundary at a bandwidth of 2.5 rad/sec.
