Abstract
An aircraft is equipped with a traffic alert and collision avoidance system. This system includes an interrogating function to interrogate a transponder on-board another aircraft. The interrogating function is activated when the aircraft is on the ground and is located below a distance threshold in relation to a take-off/landing runway. The interrogating function is deactivated when the aircraft is on the ground and one of the two following conditions is met: (i) there is no take-off/landing runway with respect to which the aircraft is located below a distance threshold greater than the distance threshold first mentioned, and (ii) after a wait time following activation, there is no take-off/landing runway with respect to which the aircraft is located below a distance threshold at least equal to the distance threshold first mentioned.
