Continuing the theme of ‘working with models’, this chapter deals with two related topics ‐ stability under constraint and response. It also deals with the theory that is concerned with six degree of freedom (6 DoF) motion, from which considerable insight into helicopter flight dynamics can be gained. Understandably, a helicopter's response characteristics can dominate a pilot's impression of flying qualities in applied flying tasks or mission task elements. The chapter provides an examination of the characteristics of the helicopter's response to clinical control inputs. It also provides a brief discussion on helicopter response to atmospheric disturbances with an emphasis on the kind of changes in the pilot/vehicle stability. Helicopter flying qualities criteria try to take account of the influence of atmospheric disturbances on the response of the aircraft in terms of required control margins close to the edge of the operational flight envelope and the consequent pilot fatigue caused by the increased workload.
