747-400F wrong fuel calculations


Recommended Posts

Hello!

 

Yesterday I have been flying my first flight with the PMDG QOSii 747-400F.

I have prepared my flight like always using PFPX, but with the default-747-400F-Profile I got a lot too much fuel for my flight from ELLX to UBBB.

The route was quite direct, with a ZFW of 260 tons. The fuel required calculated by PFPX was more than 150000 kg, weather used was AS16 real weather.

Then I tried another 747-Profile (http://forum.aerosoft.com/index.php?/files/file/3514-pfpx-boeing-747-400-performance-profiles-pack/), but that did not help, again the same required fuel.

Afterwards I was flying to UBBB with 59000 kg of fuel, which Simbrief calculated.

 

Today I wanted to try it again, the flight is UBBB to VHHH.

I tried again a few profiles, even the 747-400BCF, 747-400ERF and 747-400F.

Again I got a few warnings (exceeded MTOW and so on):

(By the way, fuel required for this flight are around 90 t)

With lowering the ZFW I could manage it to get a result of PFPX:

The 747-400 (PAX Version) works properly.

 

I think that a corrupt/wrong 747F Profile causes this issue, but it is nearly impossible to plan a flight with the 747F with PFPX...

What can I do to get this working?

 

Thank you in advance!

 

Kind regards

Matthias

How are you adding the aircraft, by profile or template ?

 

I certainly doubt a fuel difference of 60t planning the same route, weights, alternates and fuel policy.
