ATAC Corporation, an aviation analysis firm based in Santa Clara, CA, plays a major role in developing the FAA's Aviation Environmental Design Tool (AEDT), which models aircraft noise and emissions at both local and global scales. The document also includes a letter from the FAA's Seattle Airports District Office congratulating an airport on the approval of its Part 150 Noise Compatibility Program, a formal plan aimed at reducing or eliminating incompatible land uses around the airport. The FAA notes that approval of the program does not guarantee federal funding, and encourages the airport to periodically review and update the plan as conditions change.Open full document

ATAC Corporation’s webpage describing their role in developing the FAA’s Aviation Environmental Design Tool (AEDT) for local and global noise and emissions analyses. The page outlines tools and methods including modeling Continuous Descent Arrivals, animating flight trajectories, and linking airport capacity modeling with noise modeling. It also lists specific aviation environmental modeling projects at airports including San Francisco International, Los Angeles International, and Port of Oakland.
