#CMT# #/CMT# The method involves transmitting information enabling a flight management system to be aware of traffic crossing points (X1) and control sector changes from an air traffic control center to an aircraft. The information is utilized for predicting coordinates of a convergence point (X2) i.e. limit transition point (X4), at which the aircraft is supposed to rejoin its initial flight plan immediately after the crossing points have required an alteration of trajectory and later on the crossing points of a current sector. #CMT#USE : #/CMT# Method for calculating a route and four dimension prediction of altitude, speed, fuel and time of passage, of an aircraft along a flight plan by flight management system in a framework of a tactical flight instruction e.g. digital tactical clearance such as UM94 - TURN(direction) HEADING(degrees), UM95 - TURN(direction) GROUND TRACK(degrees), UM96 -CONTINUE PRESENT HEADING, UM98 - IMMEDIATELY TURN(direction) HEADING(degrees), UM190 - FLY HEADING(degrees), UM215 - TURN(directions)(degrees) and UM221 - STOP TURN HEADING(degrees), conforming to Standards and Recommended Practices (SARPS) Aeronautical Telecommunication Network (ATN), received from an air traffic control center. #CMT#ADVANTAGE : #/CMT# The method enables the flight management system of the aircraft to ensure calculation of route and prediction of the altitude, speed, fuel and time of passage, of the aircraft, in a precise and reliable manner, when the aircraft has left or anticipates leaving its initial flight plan based on an instruction from an air traffic controller, and does not have instructions about where and when to return to the initial flight plan. The method permits to avoid disturbance of traffic, thus increasing air space capacities required by future capacity plans. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation illustrating a flight plan for implementing a method of calculating a route and four dimension prediction of an aircraft.'(Drawing includes non-English language text)' AB : Route PT2-PT4 : Air route's crossing points X1 : Traffic crossing points X2 : Convergence point X4 : Limit transition point. |
