Abstract

The invention provides a system and method for managing speed constraints during required time of arrival operations. The method and apparatus includes strategies for improving required time of arrival reliability by an aircraft comprising determining a speed correction for one of AT speed constraints or an AT or ABOVE speed constraints, wherein the determining is selected from one or more of the mechanisms from the group consisting of continuous RTA speed management between constraints, padding of the AT speed constraints and the AT or ABOVE speed constraints; decelerating proactively; and using a variable guidance margin, wherein the guidance margin is a speed change not reflected in a flight plan prediction.

Description

technical field [0001] The exemplary embodiments described herein relate generally to managing the mission profile of an aircraft, and more specifically, to managing speed constraints to reach waypoints at required arrival times. Background technique [0002] Worldwide air traffic is projected to double every 10 to 14 years, and the International Civil Aviation Organization (ICAO) forecasts world air travel to grow at 5% per year until 2020. This increase may have an impact on flight performance and may increase the workload of the flight crew. To handle the expected increase in air traffic, the Next Generation Air Transportation System (NextGen) will introduce major shifts in air traffic management (ATM), eg, aircraft trajectory-based operations. Trajectory-based operations manage National Airspace System (NAS) resources by requiring aircraft to precisely follow customized 4-D trajectories containing time-consistency requirements along a specified path. This promotes a de...
