Design of maneuvers for carefree access of an aircraft to its complete flight envelope including poststall regimes is useful not only from a combat strategy point of view, but also for devising recovery strategies from an accident scenario. Maneuvers for an aircraft can be efficiently designed if a priori knowledge of its maneuverability characteristics is available to the control designers. Different types of agility metrics that characterize aircraft maneuvering capabilities have been proposed in literature based on different criteria. The concept is based on the assumption that the boundary of the AER is defined by saturation of one or more control surfaces. Therefore, a point lying on the boundary of AER is initially located using a continuation method. Using the trim point on the boundary as a starting condition, a separate continuation procedure is carried out, with the saturated control fixed at its limit value to obtain the envelope containing attainable equilibrium points.
