Hi IFC, I am once again having a problem regarding fuel. I’m currently flying from Tbilisi, Georgia to Memphis, USA in an Omni Air International Boeing 777-200er (callsign: Omni 9441) in expert server. I put 15 hours and 40 minutes of fuel in for what I thought would be an 11 hour and 40 minute flight. To my surprise I’m being told that I don’t have enough fuel to reach my destination. I had a similar problem last night using the 747-800 on a long haul from Frankfurt, Germany to Rio de Janeiro, Brazil. I posted a topic similar to this and was advised that this could be resolved by setting the flaps to 10 due to problems with the aircraft’s physics, and that I could reach my destination and save fuel by doing so. Though this is most definitely unrealistic the plane’s physics were even more so, I guess this made up for it. I did this and my fuel warning automatically vanished. In fact, I even made it to my destination 2 hours ahead of schedule. This could also have been the case due to good winds over the Atlantic. Regarding this problem please let me know if you think I will be fine with fuel later on into this flight. I have heard that the 777 does really well saving fuel as it gets lighter throughout a flight.

Look at your head wind… How much extra fuel did you pack? Check windy.com to see if you will have a head wind all flight! And if so, might be time for a plan!
How many Fuel do you have remaining?
Well after doing some research this flight should take 11 hours and 40 minutes I think I packed 15 hours and 40 minutes of fuel
Hey @Ben_McCarthy,
I believe I posted this on the other topic as well, but regarding the B747 family, you need to put in a substantial amount of extra fuel, almost 10+ hours worth more, because the aircraft is a fuel guzzler. GIG-FRA is roughly an 11 hour flight, so you need to put in the max amount for the 747 flight, which is 23 hours or so.
For the B772, as @Captain_Cign has mentioned, you have substantial headwinds, so you need to pack more fuel because your fuel burn rate is very inefficient. That being said, please make sure to also set trim, available by the pink bar, to make the aircraft more fuel efficient. I have found the B772s require about 45-50% trim settings.
Could you please tell me where you are over right now and your FL I will take a look and see if you have a headwind the whole fligh!
BTW, this is a westbound flight, so you need to have even numbered altitudes (this doesn’t make a difference in terms of fuel, but just though you should know)
The fuel will be enough, since you will also lose weight. You can fly very relaxed :)
The amber colour means you have about half an hour of extra fuel. With time, the aircraft should be able to burn so more weight off and it should turn to white
realism police out there again :)
@Ben_McCarthy where are you right now, an airport ICAO would do and where are you heading…
Oh I’ve flown through that area countless of times from Asia to Europe! This is where most of your headwinds are, European airspace should be a little more clear, so that headwind should die down!
Looks like you will have a headwind for most of your flight! Should be enough fuel though, just means more sleep (if overnight)

According to Windy.com, it looks like the most fuel efficient routing would be through southern Greenland, and the Midwest US, as you’ll get a slight component tailwind southward
Thanks for letting me know I’ll definitely take note of this. I knew there was some sort of rule regarding this, since I’m westbound if I climbed to 36,000 feet in order to be more realistic do you think I’ll burn too much fuel and continue to have this problem?
The 1000 ft climb might have burned an irrelevant amount, but majority of it will come from straight flying.
Did you use planning software like SimBrief or FPLtoIF?
I was worried about my fuel when flying from Frankfurt to Buenos Aires yesterday and had to stay below FL320 the whole flight in order to make it. Didn’t imagine retracting the flaps would save fuel even in IF haha
No lol I just didn’t want to fly over Ukraine since this is a charter airline based in the US and many airlines choose not to fly over the vacinity of the country
I don’t usually use resources like this to calculate fuel
