YSSY - KORF (routed over EGLL) in the 772. 27:41, didn’t quite get to the calculated value, I think that’s because I didn’t factor in how much fuel a very heavy 772 would burn climbing (88% vs. mid 60s and 70s on the other versions).
CYYZ - WBGG (routed over NZAA) in the 77W. 26:12, didn’t quite get to the calculated value but pretty close.
Great work, Andrew. I’ll definitely be using this on my flights. Thanks!
WOW what a tutorial! I am going to need to read over this when it is not 10:21 pm and my brain can process this. Nice job!
People really seemed to like this, so I’ll continue doing them. Next will be the four next-generation airliners. After that, I’ll leave it to community choice:
- 747 Family
- A320 Family
- 737 Family
747 Family will be next. Might leave out the VC-25, SCA, and SOFIA seeing as no one really flies them.
I’d assume that this was a relatively empty flight. Pre-COVID, it was rare to see a 77W exceed FL370/380.
@AndrewWu good job with the tutorial, keep em coming.
Okay the fact that the numbers you calculated were that close to the actual times you got is pretty darn incredible. This may be worth referring to after all ;)
For 777-300ER, never cruise above FL370. I have done hundreds of flights in that thing, it doesn’t behave like what it does in real life. If you go above that, you get extra fuel burn.
Correct. Well since the speed ranges from 0.82 to 0.89, they also fly at speeds faster than 0.84
For airlines , the arrival time matters a lot so the speed also depends upon winds and ground delay. If you encounter very strong tailwinds, you may cruise a bit faster maybe at 0.85 or 0.86 and a bit slower in case of tailwinds however in IF these things don’t matter a lot but it’ll be better for those who want to maintain their so called professionalism
That’s somewhat correct. Many airlines cruise at higher altitudes too. Air India operates them at FL390 too and I think I saw a BA 77W at FL410 but I think I deleted the screenshot. I’ll see if I have it
Still a very good tutorial though
Yeah, that’s IRL, I’m talking about pure IF. This tutorial is in no way a reference to IRL 77Ws because as hard as IF tries they’re obviously going to have some differences.
A359 is possible
A350’s fuel profile in IF is really funny actually, I have the numbers that will be in a future tutorial but the gist is that it never changes that much across flight levels.
That cool thanks for this
I have the wind-altitude trade for real 777, but this tutorial is for IF.
777 has a old flight model, so it doesn’t behave like real world.
There is a update coming remember
A359 is totally broken actually… I tested at M.85 when it came out, and it never helps to go above FL340. IRL A359 are rarely not above FL340.
I don’t think it has been changed actuallly
