Method of creating and updating an ATC flight plan in real time to take account of flight directives and implementation device

摘要

The present invention relates to a method of updating an ATC flight plan of an aircraft in real time to take account of the flight directives. A reference flight plan is designated. In tandem with the receipt of the flight directive messages originating from the ground, then verifying validity of the flight directive messages, if the message is validated in the affirmative, the messages are applied successively to the reference flight plan and stored. Managing, in real time, the complete list of these flight directives and the ATC flight plan.

1. A method of updating an air traffic control flight plan of an aircraft in real time to take account of flight directives of rank i, 1≦i≦N, which are successively loaded in a flight management system, said flight directives having two possible states, one state being “loaded and valid” and the other one being “loaded and invalid then cancelled”, said method comprising the following steps:
designating a reference air traffic control flight plan which is equal to an existing active flight plan, at the instant where the active flight plan is loaded in the flight management system in order to create the reference air traffic control flight plan; saving the reference air traffic control flight plan in the flight management system; upgrading the reference air traffic control flight plan, when the flight directive of rank 1 is loaded in the flight management system by creating a new air traffic control flight plan version 1, resulting from the updating of the reference air traffic control flight plan with said flight directive of rank 1; saving the air traffic control flight plan version 1 in the flight management system; creating and displaying on a graphic interface of the flight management system a list of loaded flight directives that include a first loaded flight directive, said list loaded flight directives indicating the corresponding state “loaded and valid” for said loaded flight directive; successively repeating the following steps upon receiving the flight directives of rank i=2, 3 . . . N, said steps including
upgrading the reference air traffic control flight plan, when the flight directive of rank i is loaded in the flight management system by creating a new air traffic control flight plan version i, resulting from the updating of the reference air traffic control flight plan with said flight directive of rank i;saving the air traffic control flight plan version i in the flight management system; andadding and displaying on said list of loaded flight directives, the flight directive of rank i indicating the corresponding state “loaded and valid” for said flight directive of rank i; and activating by a pilot the air traffic control flight plan version N then loading by the flight management system of the air traffic control flight plan on which the aircraft is slaved, wherein in case of at least one flight directive with rank j which is between 1 and N is considered invalid and has to be cancelled, applying the following steps:
initializing with the reference air traffic control flight plan;upgrading the reference air traffic control flight plan when the flight directive of rank 1 is loaded in the flight management system by creating a new air traffic control flight plan version 1 resulting from the updating of the reference air traffic control flight plan with said flight directive of rank 1;saving the air traffic control flight plan version 1 in the flight management system;successively repeating the following steps upon receiving the flight directives of rank i=2, 3 . . . j−1, j+1, . . . N;upgrading the reference air traffic control flight plan, when the flight directive of rank i is loaded in the flight management system by creating a new air traffic control flight plan version i resulting from the updating of the reference air traffic control flight plan with the said flight directive of rank i;saving the air traffic control flight plan version i in the flight management system;adding and displaying on said list of loaded flight directives, the flight directive of rank i indicating the corresponding state “loaded and valid” for said flight directive of rank i;updating said list of loaded flight directives, the flight directive of rank j indicating the corresponding state “loaded and invalid then cancelled” for said flight directive of rank j; andactivating by the pilot the air traffic control flight plan version N then loading by the flight management system into the active flight plan on which the aircraft is slaved.
