Just to clarify a couple of points of our particular problem (I am under the impression we have different situations here - although the core problem seems the same, and that communication problems between 2024 EFB and planning tools and older avionics).
For what concerns the F-35:
- all of the aircraft avionics are done in XML and use the A:GPS_XXXX variables except the map mode… which is simple map JS gauge with the option of showing the flight plan turned on.
- we still use fs9gps to edit waypoints, although we know it is being deprecated (and expect it not to work in MSFS2024).
I have retested everything right now, as we DID NOT use the EFB for flight planning on the F-35 (as it did not appear to work) but only the “VFR” map drawn on the world map.
The situation is simply that in both cases the map drawn AND the A:GPS variable DO NOT MATCH what is shown in the world map.
This is not very clear in most flight plans, but it is if the departure and arrival airports are the same (which is the typical mission profile for many military flights)…
In particular, as per my previous message:
VFR flight plan created on the World map in MSFS2020 → OK
Same “Flight plan” created on the World map in MSFS2024 → OK on the map screen (and even OK on the EFB), but KO in the plane (“drop shape” flight plan - which takes you directly back to base).
A thing I did not tried until today was creating a VFR plan in the EFB in MSFS 2024… which produced mixed results, meaning you get “some” waypoints, but at a certain point the flight plan takes you back to base “abruptly” - and the flight plan “shape” in the plane looks different from the one on the map.
It is like the logic used to generate the flight plan and map view was different from the one on the EFB and V2 avionics.
Also, the A:GPS variables seem to follow what is displayed in the aircraft map (and not the EFB).
Here is an example done as follows:
- Flight plan created with the EFB in 2024 and sent to avionics
- Flight plan in game (and on A:GPS variables) seems unrelated to the EFB (except arrival and departure airports)
In other cases, if the departure and arrival airports are different, the situation is much better - the flight plan in the map and A:GPS variables still does not match with the EFB, but it is “roughly” the same…
