MSFS2020 aircraft - Autostart and engines shutting down in runway start

[MSFS 2024] Bug Reports Aircraft
1

Version: 1.0.86.0

Frequency: Frequently

Severity: High

Marketplace package name: AzurPoly Transall C160

Context:
AzurPoly C160 Transall in free flight, starting from runway.

Bug description:
When starting from runway, engines struggle to continue running.
In some cases, before clicking on “Start flight” button, we can hear the engines shutting down, and one of both engines will actually shut down.
The issue is happening randomly.

Also, we have a fuel system trigger to detect autostart:
Trigger.1 = Name:"Autostart"#Condition:Autostart_Enabled#EffectTrue:StartPump.PAg1,StartPump.PAg2,StartPump.PBg1,StartPump.PBg2,StartPump.PAd1,StartPump.PAd2,StartPump.PBd1,StartPump.PBd2

This trigger is executed when starting from runway (see Simvar Watcher) which does not make sense as engines are already running. This does not happen in MSFS 2020.

Repro steps:

  • Load the AzurPoly C160 Transall (FS2020 package) inside FS2024 Community folder.
  • Launch a free flight from a runway.

Hello @AZP

Is this still occurring with version 1.1.10.0?
I started a dozen free flight with this aircraft but never had an engine shut down.

As for the autostart, this should no longer be triggered in the next update.

Hello @FlyingRaccoon,

I still have it unfortunately, but it is happening very randomly.

I tried to replace the FUEL_SYSTEM with a legacy FUEL section, and it seems to fix the problem, so I think it is related to a regression in the fuel system. My guess it that it could be linked to this: [FS2020 port] FUEL_SYSTEM lines to engines drain

Kind regards,
Romain

Hello @FlyingRaccoon,
FYI autostart is still triggered following 1.2.7.0 update.

Hello @AZP

None of us have been able to replicate the issue on post 1.2 versions. :thinking:
Do you still have the engine shutdown issue as well?

Can you please record a video of the problem, showing the simvar watcher and fuel system debug please? I’ll forward it to our core systems engineers.

Regards,
Sylvain

Hello @FlyingRaccoon,
It seems autostart is not triggered anymore after last update, so I guess it solved the problem.
I did not have any engine shutdown so far.

Thanks!
Romain
