thank you for your reply!
I receive the information of an average fuel consumption of 5031kg for a long haul flight, but I don't know which type of engine.
WX-T write: 4700kg per hour based on GE engine.
Mathy: on which assumptions result your figures?
Exist a great difference between GE and PW engines?
Is the fuel consumption higher/less/equal with PW engines?
And one further question: Whats the correct formula to translate the fuel flow from kg into USG.
Based on my information above: 5031kg = 1680USG per hour.
