AEDT 2a is a runway-to-runway tool that was designed specifically to replace the legacy tool the Noise Integrated Routing System (NIRS – regional noise analysis) and thus is mandated by the FAA to be used in place of NIRS. The primary purpose of AEDT 2a is to model the environmental consequences of air traffic airspace and procedure actions being designed and implemented by the FAA’s Air Traffic Organization. Guidance on how to use AEDT 2a within the framework of FAA Order 1050.1e has been created and can be found here.
