Testing instructions

A32NX: Perform a normal flight and verify approach identifier shows on the ND as before, in addition, no SID name should be displayed on the ND during preflight & takeoff/climb (like the attached picture).
A380:

1. Insert a SID on the flightplan and verify the SID name appears on top of ND.
2. Fly the SID and perform a direct to a point of the SID prior to the final one, SID name should remain visible.
3. Verify SID name disappears after last waypoint of SID is sequenced, or, after performing a direct to the last SID waypoint.
4. Insert a SID and cruise flight level in a way that it will be reached before the end of SID. Verify that the SID name disappears once cruise level is reached.

I feel like this is best implemented in the A380 ND + FMS only rather than a feature flag.

I feel like this is best implemented in the A380 ND + FMS only rather than a feature flag.

The goal is to not have specific "380 FMS" sources as much as possible, so this has to go through a feature flag, like every other configurable aspect of the flight plan management that was added because it's different between 320/380 or different 320 FMS software versions.

Agree for the ND though.
