747ER Range problem

[IanHarrison 522]

I have flown the PMDG QOTSII Qantas ER version many times on the Johannesburg-Sydney route.

After a break of a few months, I decided to fly it again. However, when I did my flight plan on Simbrief , I was informed I would have to reduce the load due to weight restrictions.

I went ahead and imported that plan into P3D v5.4. When I set up the plane and loaded the flight plan, the FMC told me that I had insufficient fuel to complete the flight.

What could have happened to change the parameters to something which is obviously wrong?.

I cannot see anywhere to increase the fuel capacity.

IRL, this route was flown for years.

Specific gravity of the fuel PMDG is using at FAOR ?

This would depend upon how you are loading fuel.

Seems to have been "one of those things". Deleted the QOTSII and reloaded base plane and then added back liveries. Initial set up shows full tanks and an adequate reserve.

Will fly tonight and see what happens.

Looks like a Simbrief problem, 747 FMC is now showing correctly.
