Aviation Environmental Design Tool (AEDT) Version 3e

AEDT 3e was released on May 9, 2022 and is the latest version of AEDT. This release is a free upgrade for existing licensed users of AEDT 2b up to 3d.

All FAA actions requiring noise, fuel burn or emissions modeling and for which the environmental analysis process has begun on or after May 9, 2022 are required to use this updated version of AEDT 3e (build 174.0.15710.1).

Guidance on the version of AEDT to be used is outlined in a memo available with documentation accompanying the AEDT 3e installer.

AEDT Version 3e Highlights

AEDT 3e introduces a number of new features, improvements and updates, including:

  • Ability to import tracks and aircraft operations in CSV files
  • Option to display only selected tracks on the map in Airports tab
  • Option to edit only selected tracks in Airports Designer
  • Support for the U.S. Census 2020 data for the population exposure report
  • Support for the American Community Survey (ACS) 5-year, 2020 data for the Environmental Justice analysis
    • Note: Limited English Proficiency (LEP) data is not available at the tract-level in the 2020 ACS 5-year data, therefore LEP analyses continue to use the 2015 ACS 5-year data.
  • AERMOD and AERMET update to version 21112
    • Aircraft thrust specific in-stack NO2/NOx ratios
    • ALPHA NO2 modeling options
    • Urban population option
    • ALPHA low wind parameters
  • Improved performance and speed of AERMOD input file generation during dispersion modeling
  • Updates to emissions calculations for boiler/heater, fuel tank, sand salt pile, and solvent degreaser based on the latest EPA approved methodologies
  • Airport, Fleet and Study database updates
BADA License Requirement for AEDT 3e

If you are a new AEDT user, please refer to the AEDT purchasing steps in the Pricing page

Existing AEDT 3b / 3c / 3d users do not need to re-apply for the BADA license for AEDT 3 in advance of downloading AEDT 3e.

Existing AEDT 2b / 2c / 2d users must apply for the BADA license for AEDT 3 even if you were previously approved for AEDT 2. This is because BADA 3 and BADA 4 are two distinct and different models. You will not be allowed to download the AEDT 3 software until EUROCONTROL approves your license request. Please visit https://www.eurocontrol.int/model/bada; the access procedure for the EUROCONTROL's OneSky Online is explained at the bottom of the page. Once you are logged in the BADA User Interface website, you can request a license. Select “Tools where BADA is integrated” as the license type and select "AEDT 3" as the name of the tool.

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.


Using the SQL Server 2017 requires additional configuration steps. Please refer to the Section 5.2.2 in the AEDT 3e Installation Manual.
