Hello,

 

today i started a triple Leg Operation (LEPA-LGAV-OMDB). I made my Fuel Calculation with PFPX. When i started in LGAV had approx. 39 Tons Fuel onboard. But i always got the message "Insufficient Fuel". When i looked on the PROG Page the remaining Fuel in OMDB should be 0.0 kg so the tanks should be empty. I am right now on my way to Dubai and checked the remaining fuel on each waypoint. The Prog Page tells me that on Waypoint X i should have 13.5 tons in my fueltanks but i have more than the double in it. So where is the problem? Attached some screens.

What's the route look like?

Why are you showing the ND? We need to see the FMC and the FUEL synoptic.

 

I noticed oddities with fuel calculation, but not with respect to externally computed values. I found the FMC seems to spit out incoherent fuel predictions.

 

Best regards,

Robin.
