Method and apparatus for flight guidance for an aircraft in windshear.

摘要

Method and apparatus for commanding an optimal flight path for an aircraft encountering a windshear condition. An airspeed rate signal equal in magnitude and opposite in sense to the windshear is applied to derive a variable rate of change of airspeed command for application to a flight director indicator (57;140). Limits - (52;131) are placed on the derived command such that the mnimum allowable speed command is stick shaker speed and the maximum the nominal speed in the absence of te windshear. The resultant command signal represents a true airsoeed rate that vields an optimal fliaht oath for the aircraft to exit the windshear condition.
