Abstract
Disclosed is a method and device for automatically protecting an aircraft against a hard landing. A measuring unit measures current vertical speed and current relative height of the aircraft. A first command generating unit generates first commands to act on the vertical speed of the aircraft by determining an intermediate command from the measured vertical speed and height and converting the intermediate command into turn angles. A speed calculation unit applies the first commands to control surfaces. The first commands are generated from the measured current vertical speed and height, taking into account a predetermined reference vertical speed, such that the aircraft touches down on the ground at a vertical speed not greater than the predetermined reference vertical speed.
