- ALPHA NO2 modeling options
- Urban population option

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.
