AMEXSY Message Flow

When filing a Flight Plan (FPL) the Status indication colours change to show the progress of the FPL in the system.

Below is an example showing an FPL for a flight from Europe to the USA or vice versa.

The user clicks on the + sign (currently shows minus in the image below, as row is expanded) in the row where your flight is shown to see the status for the different ATC units. You will see, that while the status for the ATC Unit EUROCONTROL is “Sent” (yellow), the status for the ATC Unit FAA is “Pending” (orange).

When the ACK message comes back from EUROCONTROL, the status for this ATC Unit is changed to “Ack” (green) and the status for the ATC Unit FAA is changed to “Sent” (yellow).

When the ACK message comes back from FAA, the status for this ATC Unit is changed to “Ack” (green).

In the same example, if a REJ message is returned from EUROCONTROL, then the message to the ATC Unit FAA, is never sent.

However, if an ACK message is returned from EUROCONTROL, but a REJ message is returned from FAA, then there is a valid FPL in EUROCONTROL but NOT in the FAA. This situation requires manual intervention. Our recommendation in this case, is to send a CNL message followed by a new corrected FPL.
