Longitudinal and vertical gust feed forward compensation using lateral control surfaces

In one embodiment of a method (32) to reduce vertical position errors of an aircraft, a disturbance input acting on the aircraft may be determined (36). The magnitude of the disturbance may be converted into a delta lift command if the magnitude of the disturbance is outside one or more criteria (42...

More Information
Summary:In one embodiment of a method (32) to reduce vertical position errors of an aircraft, a disturbance input acting on the aircraft may be determined (36). The magnitude of the disturbance may be converted into a delta lift command if the magnitude of the disturbance is outside one or more criteria (42,51,52). The delta lift command may be post processed (64). The delta lift command may be converted into symmetric lateral surface position commands for control surfaces (68). The symmetric lateral surface position commands may be communicated (72) to lateral control surface actuators to move the control surfaces according to the symmetric lateral surface position commands.
