Abstract
Technologies are described herein for providing additional yaw control to a multi-engine aircraft experiencing engine thrust asymmetry. A primary flight control system of the aircraft is configured to limit the operational thrust of an operating engine of the aircraft to provide additional yaw control when the aircraft is experiencing thrust asymmetry. The system includes a thrust limit module for calculating the maximum engine thrust limit to be imposed on an operating engine. The maximum engine thrust limit is calculated using inputs corresponding to the sideslip angle and the roll rate of the aircraft. The maximum engine thrust limit is imposed on the operating engine of the aircraft such that the operational thrust generated by the operating engine is limited to the maximum engine thrust limit. By reducing the operational thrust generated by the operating engine, the yawing caused by the thrust asymmetry is likely to be reduced.
