Before Installing the Digital Certificate

You must install the GATS digital certificate on your machine to see the digital signatures as signed properly. If you do not install the certificate on your machine, you will see a signature error when you try to review the digital signatures on the GATS signed documents.

The image to the right shows the error you will see when looking at a GATS digital signature without the Digital Certificate installed on your computer.

Please note that the installation of the certificate must be done for each device you will use to view signed GATS documents.

The screen shots attached were taken using Windows 10 and the dialog boxes might vary slightly if you use a different operating system.

Step 1 - Download the Certificate

Download the GATS certificate by clicking the “Download Certificate” button on the Digital Certificate Installation panel at the top of the user Dashboard.

Once the file has been downloaded, locate the file on your machine and open the downloaded file in Adobe Acrobat Reader.

Step 2 - Add to list of Trusted identities

After opening the file a dialog box similar to this one will open. The file allows you to add the FEXCO-EGATS certificate to the list of trusted identities. You will see 2 sections in the Contents part, Time Stamping Authority and www.e-gats.aero. You will need to accept both of these certificates as trusted.

Click the “Add Contacts to the list of Trusted Identities“ button to add the certificate to your list of trusted entities.
