Abstract: From the viewpoint of aircraft design, a topic on control design requirements for post stall maneuvering is tackled. It is first resolved into three basic aspects of consideration, i.e., entry into post stall region, rolling and recovery. The accompanying estimation principles are then presented, where the Cobra type maneuver is employed for basic estimation on entry and recovery, and the non sideslip roll is for further requirements. The estimated tendency in control requirements of an example aircraft configuration agrees well with that from numerical simulations.

Key words: post stall maneuvering, control requirements, estimation
