The Expedite Departure Path (EDP) is a decision support tool being developed at NASA Ames Research Center aimed at providing Terminal Area Radar Approach Control (TRACON) Traffic Management Coordinators (TMCs) with pertinent departure traffic loading and scheduling information and radar controllers with advisories for tactical control of terminal area departure traffic. One of the proposed features of EDP is to provide departure controllers with the ability to perform unrestricted climbs where procedures typically restrict departures below incoming arrival traffic streams. The potential benefits of this feature include reductions in time-to-climb, fuel burn, and aircraft noise impact to the surrounding communities. This paper focuses on the issue of unrestricted climb in congested terminal areas and describes the modeling and simulation of such climbs. First, flight data of departures in TRACON airspace were analyzed to estimate the level of uncertainties in climb trajectory prediction. Second, the existing Trajectory Synthesizer (TS) module of the Center-TRACON Automation System (CTAS) was modified to generate trajectories that closely model actual aircraft climb profiles and terminal airspace procedures. Third, an algorithm was applied to predict conflicts between trajectories of departure and arrival aircraft and to determine if an unrestricted climb is advisable. Controller-in-the-loop simulations were performed to validate the feasibility of the algorithm and evaluate human factors. Lastly, a future application of a conflict probability estimation method for EDP was examined.

Yoon Chul Jung received his B.S. and M.S. degrees in Mechanical Engineering in 1981 and 1983, respectively, from Seoul National University. He earned his Ph.D. in Mechanical and Aeronautical Engineering in 1991 from University of California at Davis. He then worked at Advanced Rotorcraft Technology as a Senior Aerospace Engineer, working in the areas of rotorcraft dynamics, control, and simulation. He has been at NASA Ames Research Center since 1998, working on NASA’s Advanced Air Transportation Technologies (AATT) project. He is currently working on the development of the Expedite Departure Path (EDP), a terminal area decision support tool for departure traffic control. His areas of interest include flight trajectory prediction and conflict prediction and resolution in the terminal area.
