I did lots of flights with the 747-4 and -8 but all the times it is always low on fuel…
Last flight i did was with a Lufthansa 748, i used simbrief for the fpl and fuel and I don’t remember really well but it seems me it was 113000 kg of fuel…the destination was LA
Above Amsterdam with an altitude of 34k feet i saw that the remaining fuel was about 6 hrs but the ETE was of 12 hrs!!!
The altitude was calculated with simbrief too…
And in the in game menu when i have fueled up the aircraft it said me approx 15 hrs
I’m going to fly the 748 again tomorrow, so can someone tell me how to avoid that problem?
