Enhanced AEDT Modeling of Aircraft Arrival and Departure Profiles, Volume 2: Research Report

The primary tool that airport operators use to measure the environmental consequences attributed to aviation is the Federal Aviation Administration’s (FAA’s) Aviation Environmental Design Tool (AEDT). AEDT offers enhanced aircraft arrival and departure profile modeling capabilities that allow users to more accurately define operational procedures and better estimate environmental impacts. AEDT contains standard departure and approach profiles for every aircraft type in its database. These standard profiles and their associated aircraft performance data have been developed by the FAA in collaboration with the aircraft manufacturers to ensure valid three-dimensional flight trajectories that lie within the aircraft performance envelope. However, through the implementation of NextGen capabilities, aircraft are using arrival and departure profiles that are not found in AEDT. As a result, practitioners often develop customized profiles that require FAA approval to incorporate them into their modeling effort, a complex and lengthy process. This project focused on developing additional standard or default aircraft approach and departure profiles that are not currently available within AEDT, additional methods to model custom approach and departure profiles in AEDT, and technical guidance on selecting the optimal AEDT profiles given a user situation. These efforts will help to close the gap between real-world and AEDT approach and departure profiles and will allow AEDT users to more quickly and accurately represent the real-world environmental consequences of aviation. During this research the authors used radar trajectory data from operations at 29 US airports to identify, prioritize, and define in a manner directly usable by AEDT, 840 potential new arrival procedures and 1410 potential new departure procedures covering the commercial aircraft supported by AEDT. The new departure procedures were created in three sets, each using a different set of assumptions. One set covers existing AEDT usage of aircraft thrust and weight assumptions, and the other two use new assumptions that could be adopted by AEDT in the future to handle thrust and weight differently. They also defined a tool that could be implemented within AEDT to allow users to make simple modifications to existing AEDT arrival and departure profiles based on a limited amount of input data to help them better match the trajectories they are trying to model. Lastly, the authors created a standalone guidance document to provide a succinct, easy-to-use resource for AEDT modelers on the topic of arrival and departure profiles.
