ANALYSIS OF ARRIVAL MANAGEMENTPERFORMANCE WITH AIRCRAFT REQUIRED TIMEOF ARRIVAL CAPABILITIES

摘要

This paper describes a concept for 4D trajectory-based operations in the arrival phase of flight, using navigation functionality that is available on many commercial jet airplanes. This functionality includes a Flight Management System (FMS) capable of Area Navigation (RNAV), Vertical Navigation (VNAV), and with the capability of navigating to a Required Time of Arrival (RTA) at a specified waypoint. It is assumed that the Air Traffic Management (ATM) automation system includes the capability of producing an optimized arrival plan that maximizes the throughput of a large airport, while enabling the FMS to fully utilize these capabilities. The analysis presented here is focused on the use of the RTA function during the initial arrival phase, starting in en route airspace while the airplane is still in cruise, through the initial descent to the terminal area meter fix. This arrival management concept is consistent with the automation architecture for Time-Based Metering, already in use or under development by several Air Traffic Service (ATS) providers, and is expected to evolve towards 4D trajectory-based operations.The paper presents an analysis of the performance of an RTA function that has speed control authority both in cruise and descent. The analysis is performed using the Boeing Trajectory Analysis and Modeling Environment (TAME), which is a MATLAB-based ATM modeling capability that includes performance characteristics such as lateral navigation, wind prediction and trajectory prediction accuracy, as well as an arrival management function, and uses a Monte-Carlo simulation framework to produce performance result.
