AI aircraft via AICreateParkedATCAircraft stuck in pushback state, never move

Version: 1.7.28.0

Frequency: Consistently

Severity: High
**
Context:** FSLTL aircraft injected via AICreateEnrouteATCAircraft or AICreateEnrouteATCAircraft_EX1

Similar MSFS 2020 issue: no issue with MSFS2020

Bug description:
We started noticing this when SU5 released… it was not an issue with any of the SU5 beta releases.

AI aircraft injected via SimConnect using AICreateParkedATCAircraft or AICreateParkedATCAircraft_EX1 don’t pushback. They appear stuck in STATE_PUSH_BACK_CONTINUE. No pushback tug appears and the aircraft never moves.

Occurs at default airports
We’ve tried changing sim settings related to ground vehicles with no change.
Interestingly, with increased logging on our side, it seems the aircraft goes through the different pushback states twice:
STATE_PUSH_BACK_BEGIN → STATE_WAIT_FOR_ENGINE_START → STATE_PUSH_BACK_CONTINUE → (couple second delay) → BEGIN (again) → ENGINE_START (again) → CONTINUE (again)
From there, the aircraft just sits, forever.

Not sure what could have changed in that final SU5 release. I also have not seen any other complaints about a pushback issue from others with SU5, so not sure where to start.

Confirmed with some others this is an issue, not just me.

Aircraft injected using SimConnect_AICreateParkedATCAircraft.
At a later time, a flightplan is attached to the aircraft using SIMCONNECT_AISetAircraftFlightPlan

Aircraft starts the normal state changes as described above, but no pushback occurs. No pushback tug is spawn’d, etc.
Again, started with full SU5 release, there was no issue in any of the previous SU5 beta releases.

After some additional testing, this appears to be related to either pushback settings or the pushback tug itself??

If I set PUSHBACK = 0 in the aircraft.cfg of a model and that model is injected into MSFS2024 SU5, it seems to pushback just fine. But if I set PUSHBACK = 1 in the aircraft.cfg, it does not. And in the sim, the AI aircraft itself is in the correct state, but the pushback tug never spawns in sim and the aircraft never moves.

@FlyingRaccoon I hate to ping you directly, but hoping someone on the team can take a look?

I’ve also seen some posts in the normal forums with users of similar injection tools (AIG) with similar pushback-related complaints.

Quite a few reports of this now. Confirmed setting PUSHBACK = 0 to the aircraft.cfg of injected models does allow the aircraft to “pushback” and taxi.

Any response from the devs on this would be welcome, please.

@Boris … or any other dev… any chance we can get a confirmation of this being a known issue with SU5 and something that is being looked at? Much appreciated…

Hello @BirdmanRS

Yes, we witness this issue on several other traffic injection tool.
Pushback vehicles appear to spawn on the wrong parking spots:

This is being investigated.

Thank you for offering, but this one is rather straight forward so we should be good. :wink:

SU5.1 beta 1.7.33.0 does indeed resolve the pushback issue in MSFS2024. Thank you!
