Systems and methods for controlling aircraft arrivals at a waypoint

Abstract

Example systems and methods for controlling aircraft arrivals at a waypoint are disclosed. An example method for controlling aircraft arrivals at a merging waypoint includes defining a tie waypoint at a first distance from the merging waypoint and generating a first parameter set of flight instructions for aircraft arriving at the tie waypoint. The first parameter set includes an aircraft speed instruction for a target separation between a first aircraft arriving at a target waypoint downstream of the tie waypoint and a second aircraft arriving at the target waypoint. The example method includes defining a diversionary flight path at a second distance from the merging waypoint. The second distance is less than the first distance. The method also includes generating a second parameter set of flight instructions for the aircraft arriving at the diversionary flight path. In the example method, the second parameter set includes instructions for the first aircraft to follow at least a part of the diversionary flight path before flying to the merging waypoint. A total flight path distance of the first aircraft is to increase when an expected arrival of the first and second aircraft at the target waypoint has a separation that is smaller than a threshold separation.
