Aviation Environmental Design Tool (AEDT) Version 2d

Note that the information on this page is for AEDT 2d. Please visit the AEDT Version 3e page for information on the latest version of AEDT.

All FAA actions requiring noise, fuel burn or emissions modeling and for which the environmental analysis process has begun on or after September 27th, 2017 are required to use AEDT 2d. Additional information on the use of AEDT versions and their modifications is outlined in a versioning memo available on the AEDT website.

AEDT Version 2d Functionality

A high level summary of AEDT 2d functionalities is listed below:

  • All noise, emissions, and emissions dispersion metrics from INM, EDMS, and AEDT 2a
  • Creation and editing of point-type and vector-type flight tracks in the user interface
  • Creation and editing of dispersed tracks in the user interface
  • Emissions dispersion from curved flight tracks
  • Emissions from airplane and helicopter startup and taxi phases of flight
  • Airplane taxi delay and sequence modeling
  • Noise from helicopter taxi
  • Emissions from auxiliary power units, ground support equipment, and a wide variety of other non-aircraft emissions sources
  • Fuel consumption and emissions for military aircraft
  • Modeling of multiple airports in a single study
  • Creation of custom altitude controls for airplanes
  • Time audible noise metrics
  • Number above noise level
  • Dynamic grid support for all system noise metrics
  • Environmental justice population identification
  • Background emissions concentrations
  • Emissions dispersion contouring and output selection – ability to select specific source groups, averages, and rankings
  • Migrate Studies feature - copies AEDT studies from a SQL Server 2008 R2 instance to a 2012 instance
  • Creation of MOVES roadway, parking facility, and construction zone links in the user interface
  • Noise contour generation for point-type receptor sets
  • Combine acoustic metric results with different receptor sets
  • High fidelity weather support for MERRA-2 and WRF

More details about the differences between INM, EDMS, and AEDT versions are summarized in the AEDT Functionality Comparison chart.

AEDT does not include on-road mobile ground emissions sources like roadways and parking lots because EPA replaced MOBILE (the on-road mobile ground emissions model included with EDMS) with the Motor Vehicle Emissions Simulator (MOVES) in 2013. Emissions for on-road mobile sources and construction equipment, a non-road emissions source, will be estimated through MOVES. AEDT, however, provides functionality to the user to import the emissions of these sources and model them for their air quality impacts. The FAA provided guidance for using AEDT together with MOVES for studies that include on-road mobile ground and construction emissions (see Using MOVES with AEDT).

System Requirements and Specifications

The recommended specifications are listed with suggested minimums where applicable. AEDT is a stand-alone Windows based application. However, through the use of Microsoft SQL Server connectivity, it is possible to connect multiple computational clients to one central database server. AEDT requires administrative privileges for installation and execution.
