Hello, everyone. I am flying the Air Force 1, 747 too LAX. Is it possible that someone can refuel me? I’m on Training Server maybe 100 miles from Paris right now. My tag is Glevolution and my call sign is Air Force 1.
No you’ll lose more fuel since those two engines will be working harder resulting in more thrust usage to produce a sufficient amount of thrust without the help of the other two engines ultimately causing more fuel to be used. Use all the engines available.
As said above, your engines will have to work harder. You may not even be able to maintain speed during cruise, so you’ll have to descend, and cruising at a lower altitude exposes you to more wind and greater air pressure. Turn off only one engine at most.
