ABSTRACT:
This invention makes use of a pressure sensor, which is installed on the wing's surface of the aircraft, to sense the varied air pressure which comes from ground-effect on the wing's surface. A control apparatus is comprised of pressure sensor, a device of signal treatment and the device of elevator control. This apparatus solves the problems of excessively low ground-effected flying altitude and low efficiency of the whole aircraft.
