In the structure of Civil and Military Requirements, good flying qualities are conferred to ensure that safe flight is guaranteed throughout the operational flight envelope (OFE). This chapter examines quality criteria and the associated flight test measurement techniques. It shows the roll axis quickness criteria boundaries from Aeronautical Design Standard (ADS)‐33, including the definition of the attitude parameters required to derive quickness. A key flying qualities concern relates to the ability to trim a helicopter with adequate control margins remaining for manoeuvring, throughout the OFE. In hover, the control power in the pitch axis is essentially the same as in the roll axis, scaled by the ratio of control ranges. The chapter covers two areas that are relatively immature in terms of the existence of any underlying flying qualities database: multi‐axis response criteria and novel response types.
