Step 1. Apply for the BADA License for AEDT 4

IMPORTANT: All non-FAA and non-EUROCONTROL users of AEDT 4a must apply for the "BADA License for AEDT 4", This is necessary even if you were previously approved for the BADA license for AEDT 2.

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 4" as the name of the tool. Please review this guide that describes the BADA license request workflow.

You must request and acquire a BADA license in advance of purchasing AEDT. If your BADA license request is denied by EUROCONTROL, then you will not be allowed to purchase AEDT software.

The European Organization for the Safety of Air Navigation's (EUROCONTROL) Base of Aircraft Data (BADA) is a critical database integrated into AEDT.
The BADA license is free to obtain.
EUROCONTROL can take up to two weeks to respond to an individual license request. Incomplete information in the BADA license application form can delay the license approval process.
Each site that is licensed to use AEDT must have at least one AEDT BADA license issued to a user at that site. The AEDT BADA license should be obtained by a user who has the authority to agree to the BADA agreement on behalf of their company and will be treated as an official point of contact by EUROCONTROL.
Users who already possess a BADA license tied to another application, such as EDMS, must obtain a BADA license specifically for AEDT.
BADA “standard” licenses are not applicable to AEDT and cannot be used with AEDT.

Step 2. Register for an user account on the AEDT Support Website

Once your BADA license for AEDT 4 is approved, create a user account on the AEDT Support Website by clicking the Register page

Step 3. AEDT Support Team will activate your account

AEDT Support Team will verify that at least one user at your site has an AEDT BADA agreement, then activate your account.

FAA employees: FAA employees do not need to apply for the BADA license. Contact the National Service Center (nsc@faa.gov) and request the Aviation Environmental Design Tool (AEDT). NSC will direct you to a software request form. Budget at least one hour for an IT technician to install AEDT onto your computer.

US Federal Government Agencies: US Federal Government agencies may receive AEDT at no cost (up to 3 installations/seats). A written request must be submitted to AEDT Technical Support at aedt-support@dot.gov in the form of a scanned copy of the request on agency letterhead.
