PMDG 777 - Fuel Disagree Warning

[mjchernis]

Been really enjoying FSIPanel with the 777 and most of the time it seems fine. However, sometimes I get a an orange "Fuel Disagree" warning and a non-normal checklist entry when setting up an approach.

I do set the payload (50%)/fuel (10%) in the FS Actions menu before repositioning the aircraft with FSIPanel. Any ideas?

Hi,

Could you post a photo of the fuel and FMC setup ?

Here you go..

Was away from computer for a few days. Have some more screenshots but this only lets me upload 3. When starting the flight I set fuel to 10% and payload to 50% before repositioning with FSIPanel. This is with version 1.0.100 of FSIPanel and v2.0.37 of the 777.

Thanks,

Mark

Hi, Do you set fuel using the 777 FMS ?
Never heard of this issue from anybody else and unable to reproduce.
FSiPanel does not set any fuel unless you load a training scenario.
Maybe on 2nd or 3rd approach ?

Yes. I do set the fuel using the 777 FMS—usually 10%. Not a scenario and the 1st flight. Happened again today.

What’s weird is the fuel shown is definitely different from the fuel I set with the FMS so something is changing it.

It seems more likely to happen with low fuel weights like 10% and when I select a Star.

I can replicate it..

Launch MSFS
Spawn PMDG 777 on PHNL RW08L (can be any airport but for this example)
Set FS Actions-Fuel-Level 10% (this is important)
Set FS Actions-Payload 50%
Load FSIPanel
Select RW08L
Select Fix: Star: Booke8, Transition: Danno, Waypoint: LIH

Validate Fix
Move Aircraft

I think it may happen when you set fuel below a certain level and the "totalizer" is less than the "calculated" values on the progress page.

Any thoughts on this one? Still happening. Seems to happen whenver I set fuel to less than 15% at the start. I think the pictures above show it clearly and it is easy to recreate. For whatever reason, the plane thinks I have much different amount from what I acutally loaded.

Yep looks strange as fuel is set through the FMC and FSiPanel does not interact with it anymore.
Did you try to press on LSK4L I guess (USE), does it fix it ?

That works!

It is strange. For some reason the plane is wrongly calculating that it needs a lot more fuel than I have loaded.
