Abstract
The present invention relates to a method for automatically preparing an update of audio communication frequencies between aircraft and ATC stations on the ground, a method making it possible to reduce the communication time associated with the necessary frequency changes between control sectors, therefore limiting the frequency space requirement, and reducing the workload due to the manipulations and control of these frequency changes, both for the air traffic controllers and for the aircraft crews, and wherein the flight plan or the current trajectory followed by the aircraft is dynamically coupled with the geometry information of the control sectors overflown by the aircraft and that, thereby knowing the intersection points of the flight plan with the sector limits, the frequency changes and sector name are prepared before each change of sector, while warning the pilot of their imminence.
