CONTROL STICK LOGIC IN HIGH-ANGLE-OF-ATTACK MANEUVERING

The relationships between pilot control stick inputs and control effec tor deflections are examined. Specifically, we address multiply redund ant control effector arrangements and command-driven control laws. Dur ing high-angle-of-attack, low-dynamic-pressure maneuvering, there is b oth a control power and control coordination problem. Control effector deflections are not one to one with pilot inputs, and the maximum cap abilities of effecters to respond to pilot inputs varies dynamically w ith the state of the airplane. The problem is analyzed in the context of a generic control law that continuously regulates sideslip. A means is presented to relate the fixed control effector limits to the dynam ically varying control response limits. This information may be used t o re-establish the one-to-one correspondence of pilot inputs to contro l capabilities.
