Method for generating operational data of at least one airport infrastructure, comprising the following steps: - an acquisition step, implemented by an acquisition module, consisting in acquiring and in transmitting movement tracking data sets for a plurality of aircraft present in a detection volume of predetermined dimensions around the airport infrastructure, each of the said movement tracking data sets being associated with one of the said aircraft, each of the said movement tracking data sets comprising successive position data and flight data of the aircraft considered, a plurality of flight data being associated with each of the said position data; - a first identification step, implemented by a first identification module (IDEN1), consisting in identifying by splitting the paths of the aircraft into movement phases on ground a path for each of the said aircraft on the basis of the movement tracking data set of the said aircraft considered, of at least one taxiway of the airport infrastructure and of at least one parking zone of the airport infrastructure; - a second identification step, implemented by a second identification module (IDEN2), consisting in identifying and in transmitting, for each of the said paths complying with predetermined conditions, one or more phases, each of the said phases being associated with phases data, position data and flight data of each of the said aircraft; - a generation step, implemented by a generation module, consisting in generating a plurality of first sets of operational data and a plurality of second sets of operational data, each of the said first sets of operational data comprising the flight data and the phases data associated with one of the said aircraft, each of the said second sets of operational data comprising the position data of the said aircraft; and - a transmission step, implemented by a transmission module (TRANS), consisting in transmitting the said first sets of operational data and the said second sets of operational data to a user system, the phases data being a phase identifier, a rank of phase in the path of an aircraft, a phase start time and a phase end time, a duration of phase, a type of phase, a departure or arrival time at a parking zone or on a taxiway. - an acquisition step, implemented by an acquisition module, consisting in acquiring and in transmitting movement tracking data sets for a plurality of aircraft present in a detection volume of predetermined dimensions around the airport infrastructure, each of the said movement tracking data sets being associated with one of the said aircraft, each of the said movement tracking data sets comprising successive position data and flight data of the aircraft considered, a plurality of flight data being associated with each of the said position data; - a first identification step, implemented by a first identification module (IDEN1), consisting in identifying by splitting the paths of the aircraft into movement phases on ground a path for each of the said aircraft on the basis of the movement tracking data set of the said aircraft considered, of at least one taxiway of the airport infrastructure and of at least one parking zone of the airport infrastructure; - a second identification step, implemented by a second identification module (IDEN2), consisting in identifying and in transmitting, for each of the said paths complying with predetermined conditions, one or more phases, each of the said phases being associated with phases data, position data and flight data of each of the said aircraft; - a generation step, implemented by a generation module, consisting in generating a plurality of first sets of operational data and a plurality of second sets of operational data, each of the said first sets of operational data comprising the flight data and the phases data associated with one of the said aircraft, each of the said second sets of operational data comprising the position data of the said aircraft; and - a transmission step, implemented by a transmission module (TRANS), consisting in transmitting the said first sets of operational data and the said second sets of operational data to a user system,
