Fuel Valve Initialization State Incorrect Without Electrical Power

Frequency: Constantly
Version: 1.5.27.0
Severity: Blocker

Bug Description:
On first load, certain fuel valves appear in the open position even though they should be closed in a cold-and-dark state. Because the modern fuel system requires electrical power to move valves, they cannot transition to the correct state until power is briefly applied, which causes an incorrect valve position at initial spawn.

We need accurate initial valve states because these positions are displayed directly on our EFB fuel schematic for the user.

Hello,

Did you try to set the valve position in the apron flt ?

For example in the 737 apron.flt :
[FuelSystem.0]
Valve.1=False
Valve.2=False
Valve.3=False
Valve.4=False
...

Regards,
Boris

We tried to do a first load update which is similar to the FLT file method. But that did not work!

UPDATE: Using the FLT file method worked! Thanks.
