How can I see an ATC route change in the retrieved IFR flight plan?

To see an ATC route change in the retrieved IFR flight plan, the following is required:

1. File Credentialed: The vendor must file credentialed:

   1. This means that web services are sent with the pilot’s Leidos user name (webUserName parameter).

   2. The pilot must authorize the vendor to file on their behalf through Leidos Flight Service website.

2. ATC Notices:

   1. The pilot must set up ATC Notices from the Leidos Flight Service website. When this happens, Leidos is able to receive route change alerts from ATC for each filed flight.

   2. The vendor can use the atcNotices field in the RetrievePilotProfile response to check if the pilot is registered for ATC Notices.

   3. When Leidos receives an ATC notice of a route change, we update the expectedRoute field in the FP.

   4. When the pilot receives an ATC Notice for a route change, they are prompted to accept it.

      1. If they accept it, the Flight Plan route field is amended to whatever is in expectedRoute.

      2. If they do not accept it, then the route field remains unchanged, but the ATC amended route is still stored in expectedRoute field.

3. Retrieve Flight Plan: The vendor can use the RetrieveFlightPlan web service to retrieve the flight:

   1. The expectedRoute field in the response will contain the ATC amended route (if the above requirements are met).

Contact Vendor Support to arrange a test in the Leidos Test Lab

This capability can be tested in the Flight Service Test Lab by coordinating a test with Leidos Vendor Support at R-FFSP-WebServicesSupport@leidos.com.

...

1. Vendor: Setup for the test using the steps above.

2. Vendor: File an IFR flight plan in the Test Lab.

   1. Note: Testing in live operations is not permitted.

3. Leidos: Inject simulated ATC route change.

4. Vendor: Retrieve the flight plan and observe the expectedRoute field.
