1. A method of controlling air traffic, comprising the steps of:

  • a ground based computing system receiving an aircraft trajectory data that defines a planned flight trajectory for each of a plurality of aircraft, from an on-board flight management system (FMS) of a respective aircraft, the ground based computing system utilizing the aircraft trajectory data to establish a required time of arrival (RTA) at a destination for each of the aircraft, the RTA being established for each of the aircraft to arrive at the destination in a desired sequence, the ground based computing system, assessing an aircraft intent during flight of each of the aircraft to estimate compliance with the RTA, the aircraft intent assessment comprising obtaining an aircraft performance data from the flight management system (FMS) of each of the respective aircraft and synthesizing the obtained aircraft performance data with aircraft trajectory data based on an observation of the respective aircraft and data from a physical environment, to obtain an estimated trajectory of the respective aircraft; and

    the ground based computing system adjusting the desired sequence, if it is found that any of the respective aircraft are not complying with the RTA.
