Trajectory Management - Arrivals (RNAV/RNP w/ 3D and Required Time Arrival)

This project will ensure that the safe and efficient transition of aircraft from en route to terminal airspace with appropriate sequencing and spacing. Several key mechanisms will be necessary to support this more efficient transition. Required Navigation Area Navigation/Required Navigation Performance (RNAV/RNP) procedures with vertical constraints and required time of arrival will provide the precision necessary to avoid using extra separation between aircraft. Use of metering times at key merge points will be used by air traffic managers as used today in Center-TRACON Automation System Traffic Management Advisory (CTAS TMA). In this type of operation, an aircraft's meter point time (MPT) is used to determine when it enters into the TRACON airspace and is given clearance to continue to the assigned runway. Metering must take into account runway load balancing and will serve to reduce (but not eliminate) the need for delay absorption needed inside the TRACON.
