TRB's Airport Cooperative Research Program (ACRP) Web Only Document 36: Enhanced AEDT Modeling of Aircraft Arrival and Departure Profiles, Volume 1: Guidance supplements the Aviation Environmental Design Tool (AEDT), which computes noise, emissions, and fuel burn as a result of aircraft operations. The guidance document provides users of AEDT with information about varying approaches to profile modeling.

Accompanying the guidance, Volume 2: Research Report documents the approaches used to develop the AEDT guidance outlined in ACRP Web Only Document 36: Volume 1. Appendices A-E of volume 2 are available on a microsite: Supporting Materials for ACRP Web-Only Document 36.
