An improved system and technique is disclosed which enables an aircraft control system to bring an aircraft to hover with no direct measurement of ground speed. The system includes a device for numerically calculating a value for ground speed based on a differentiation of aircraft position as measured from conventional ground reference navigational aids. The computed value of ground speed is compared with values representing heading and true air speed to generate a computed value of wind. The computed value of wind is then resolved into vector components...
An aircraft control system for achieving a hover condition comprising: means for providing a signal representing aircraft headwind; means for providing a signal representing aircraft airspeed in a direction opposite to headwind; means for subtracting said signal representing headwind and said signal representing aircraft airspeed, said means for subtracting including, means for combining said signal representing headwind and said signal representing airspeed to produce a fade signal, and means for combining said fade signal with said signal representing ...
