Hey again IFC! I was planing on flying from Frankfurt to Washington Dulles soon on the 747-8. Is it an accurate fuel burn to real life and would it be ok to use SimBrief to plan the flight?
I would definitely recommend using flaps during the cruise, as it tends to stall. I am not sure about the fuel burn though, but after my experience with another 4-engine aircraft, the A340, which made me end up hours from my destination, I would definitely pack some extra fuel.
Or just avoid the embarrassing looks you’d get for using them at all in that phase, and use 50-60% trim, while gradually easing yourself in and out of that trim setting when you start and when you’re done. Fuel efficiency and stability are almost guaranteed.
Hmmm. Maybe I’ll just be safe and do the a350 from Munich. I was gonna do the 747 to Dulles then the a350 to Munich but I’ll just stick with the a350 both ways for now… Plus its an overnight flight while I’m sleeping so I doubt I can change the trim at cruise!
Hope this helps! Safe travels.
You shouldn’t ever have to use flaps during cruise, even when at MTOW. You’ll often get clean speeds above 260-270 knots on the 748 which may be your issue so you’ll need to ask for high speed below 10,000. If you are stalling at cruise you are doing something very wrong - may need to check your weight balance and trim.
I maybe confuse the B748 with the B747-400 but one does have problems at normal initial cruise heights for sure. It’s because the B747 has a more accurate fuel burn that way. The thing I wrote about stalling was wrong. I must have confused those two things, sry.
I had fuel burn problems though, even though I used 60% trim. Other users also experienced that. It may be because as am not flying it properly, as I am rarely flying it
Considering it’s called the “Intercontinental” yes it’s good for a long haul
I would actually recommend the A330 if you want to. The 747 is just a no at least for me
The 747 is an absolute workhorse. Easy plane to fly.
