Abstract
This system for displaying, on the flight deck of an aircraft travelling on the surface of an airport, an airport map mentioning the surface traffic, for the purpose of a taxiing aid and protection of the ground movements of the aircraft, shows on the airport map only the traffic occupying the airport thoroughfares close to the aircraft, this closeness being defined by the existence of a joining path comprising a number of thoroughfare sections that is less than an arbitrary limit of the order of 1 or 2.
