[NO BUG] [2.9.7.58923 MT] Minimum internal fuel settable in mission editor too high

[Stickler]

When setting an internal fuel weight below 2640 lbs for a clean aircraft in the mission editor, the aircraft will still spawn with 2640 lbs of fuel.

Only settings higher than 2640 lbs in the mission editor will increase the spawn fuel of the aircraft to the selected value.

How do you determine that? By looking at the fuel counter? If so, you are just running into its built-in inaccuracies of the sensor placement within the tanks.

See here, everything is 0 if I select 0 in the Mission Editor:

Also note that the indicated fuel in LBS depends on density (influenced by many factors, such as temperature) as well.

3000 lbs in ME:

Result in 3000 lbs fuel upon spawn.

2000 lbs in ME:

Result in 2640 lbs upon spawn.

Cant reproduce, please send the mission file, thank you.

Thank you. The mission has unlimited fuel checked, which is why the Phantom will always magically reset tank 1 and tank 2 to full. The fuel threshold you found happens to be the sum of a full cell 1+2. Disable unlimited fuel and it will work as you expected, cheers

Thanks. I was operating under the implicit assumption that unlimited fuel meant that whatever fuel you set in the ME is the fuel you initially have. Good to have Heatblur's solution documented here for future reference.

Im not sure if there is an unwritten rule to how "unlimited fuel" is supposed to be implemented. DCS-wise its just a true/false flag and the thirdparty has to figure out what to do with it.

We decided to keep our fuel system so that even with the "cheat" enabled players can still experience the full system, including shifting CG during AAR. So for the Phantom we just set some form of minimum fuel level that would ensure you never run out of fuel, but otherwise keep the fuel system without cuts or simplifications

I think that’s a smart approach!
