Disclosed is a system (100) to detect aircraft ground proximity. The system (100) comprises 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. Also disclosed is an aircraft (10), and a method (400) to detect aircraft ground proximity.
