Abstract
A system 100 to detect aircraft ground proximity including: a transmitter 110 for transmitting a radio frequency signal along an extended landing gear 20 of an aircraft 10, a sensor 120 configured to detect a parameter of the radio frequency, and a controller 130 configured to detect a change in the detected parameter on the basis of an output of the sensor 120, and to issue a landing signal when the change in the detected parameter meets a predetermined criterion. The predetermined criterion is indicative of a certain aircraft ground proximity.
