Aircraft start with almost no fuel on MFS24

Version: 1.1.9.0

Frequency: Consistently

Severity: Blocker

Marketplace package name: N/A

Context: H145, H160 loaded from Community. H225 is impacted but there is a workaround to set fuel coded in, which conflicts with whatever the sim just did prior.

Similar MSFS 2020 issue: Works on MFS20

Bug description: The aircraft has all fuel removed when clicking “Ready to fly” for a runway start. It works fine when starting manually on the ramp.

Repro steps:

  1. Install H145 or H160
  2. Load a flight on the runway
  3. click Ready to fly

Expected: Aircraft has 50% fuel in all tanks
Actual: Aircraft has almost no fuel in only some of the tanks. The fuel is removed when clicking ready to fly. The user must add fuel manually.

I use .FLTs to configure the plane correctly, but they are loaded differently in fs24.

I have the same problem with a 2020 aircraft I am porting over.

Hello @davux3 (@EarliestBaton22 FYI)

In MSFS 2020, the aircraft was spawned on the runway directly, only relying on runway.flt
In MSFS 2024, there is now a taxiway RTC before you click “Ready To Fly”. Taxi.flt is therefore loaded.

On the H145, taxi.flt contains a [Fuel.0] section with selector positions but no [FuelSystem.0] section.
In this situation, the sim falls back to legacy system and tries to load [Fuel.0] fuel levels, setting 0 everywhere as it can’t find any values in the FLT.

Defining a FuelSystem section, just like you did in your runway.flt will solve the issue.
I will have this looked at in case we can avoid such regressions.

Sylvain

Thanks for this information. I’ve edited my taxi.flt file and it solved the problem. I didn’t even recall having such a file as I wasn’t aware it was ever used in 2020.

Hello @davux3

This should be fixed in SU1 beta 1.3.10.0

I experienced this today. @FlyingRaccoon thanks for the fix.
