Hello IFC,
I have been trying to do flights recently and I have given the plane plenty of fuel, yet is says I need more. For example, I was flying a 767 and it had 11h of fuel, but when I took of it said it had only 4h of fuel.
Hi!
It’s probably because it is instant, so when you are climbing it changes (because you are using more fuel in order to climb)
Check again when cruising
