Multiple transition RNP approach procedure
First Claim
1. A method for controlling airport traffic that includes both aircraft flying in RNP mode and aircraft not flying in RNP mode, the method being implemented by an air traffic control system including a processing device, the method comprising:
- routing, by the air traffic control system, a plurality of aircraft including routing a first aircraft flying in RNP mode from a waypoint to a downwind leg of a runway approach and routing a second aircraft not flying in RNP mode from the waypoint to the downwind leg of the runway approach;
determining, by the air traffic control system, using sequencing and separation requirements, a first one of a fixed plurality of predetermined RNP transition points for the first aircraft to fly to, a second one of the fixed plurality of predetermined RNP transition points for the second aircraft to fly to, and an associated speed of approach for the second aircraft when the first aircraft and the second aircraft are moving from the downwind leg to a final approach leg;
routing, by the air traffic control system, the first aircraft using the first determined RNP transition point and a speed of approach of the first aircraft so that the first aircraft can approach the runway and maintain separation and sequencing of the first aircraft relative to other aircraft of the plurality of aircraft approaching the runway;
routing, by the air traffic control system, the second aircraft to the second determined RNP transition point for a turn to the runway approach; and
monitoring, by the air traffic control system, the speed of approach and a direction of approach of the second aircraft to maintain separation and sequencing of the second aircraft relative to the other aircraft of the plurality of aircraft approaching the runway.

Abstract
A required navigation performance (RNP) approach method is described that includes providing a plurality of fixed, predetermined waypoints associated with at least one runway of at least one airport, providing a predetermined plurality of constant radius turnpoints connecting a downwind leg of the runway to a final approach leg of the runway, and assigning one of the constant radius turnpoints to an aircraft capable of flying an RNP approach, the turnpoint selected to provide separation from other approaching aircraft and a landing time for the aircraft.

8. An air traffic control (ATC) system comprising:
-
a processing device; a memory; and an interface for communicating with aircraft, said system programmed with a plurality of geographical points that define, with respect to a runway, a downwind approach path, a final approach path, and a plurality of constant radius paths connecting the downwind approach path to the final approach path, said system further programmed to; define a first approach path for a first approaching aircraft flying in RNP mode and define a second approach path for a second approaching aircraft not flying in RNP mode by selecting, for each of the first aircraft and second aircraft, one of the constant radius paths for each of the first aircraft and second aircraft to fly; assign a first speed for the first aircraft to maintain at various points along the first defined approach path, the first defined approach path and first assigned speed calculated to maintain a separation between other aircraft flying defined approach paths, at assigned speeds, that include one of the constant radius paths; and monitor a second speed and a direction of approach of the second aircraft to maintain separation and sequencing of the second aircraft relative to the other aircraft flying defined approach paths. - View Dependent Claims (9, 10, 11)
