Abstract
The invention relates to a method of assisting in the navigation of an aircraft comprising a step for updating a flight plan according to a new clearance originating from an air traffic control authority and received on board by a ground/onboard communication system. The clearance comprises an action conditional on the flight plan linked to a floating point of the path defined by a time constraint of the aircraft; on receipt of the new clearance, the update is performed directly by means of the FMS linked to the communication system. This is a predictive method.
Claims15
A method of assisting in navigation of an aircraft, comprising:
- receiving, by a ground/onboard communication system, a new clearance originating from an air traffic control authority;
- and
- updating, by a flight management system linked to the communication system upon receipt of the new clearance, without intervention of a pilot of the aircraft, a flight plan which includes a lateral path and a vertical profile associated with clearances, the flight plan being updated according to the new clearance, wherein the new clearance comprises an action conditional on the flight plan associated with a floating point of the lateral path and/or of the vertical profile, defined by a time constraint of the aircraft.
A method of modifying a flight plan of an aircraft by a flight management system onboard the aircraft, the method comprising:
- receiving a clearance instruction from an air traffic control authority, the clearance instruction comprising an action to be performed upon occurrence of a condition;
- generating at least one pseudo-waypoint in the flight plan at which the condition of the clearance instruction is estimated to occur;
- determining if modifying the flight plan according to the clearance instruction and the pseudo-waypoint is achievable;
- sending a rejection message to the air traffic control authority if it is determined that modifying the flight plan according to the clearance instruction and the pseudo-waypoint is not achievable;
- and
- modifying the flight plan if it is determined that modifying the flight plan according to the clearance instruction and the pseudo-waypoint is achievable.
