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

The relationships between pilot control stick inputs and control effector deflections are examined. Specifically, we address multiply redundant control effector arrangements and command-driven control laws. During high-angle-of-attack, low-dynamic-pressure maneuvering, there is both a control power and control coordination problem. Control effector deflections are not one to one with pilot inputs, and the maximum capabilities of effecters to respond to pilot inputs varies dynamically with 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 dynamically varying control response limits. This information may be used to re-establish the one-to-one correspondence of pilot inputs to control capabilities.
