how much fuel do i need?

[Apostoliskf98]

is there any way to know how much fuel is necessary for a specific route? or i just full it?

Fuel quantity and burn rate is so broken right now though.

Ill tell you this if your flying from SEA-ICN(Korea) In a 747 your gonna need about 245xxxLBs of fuel
Taking the airbus from SEA-SFO you will need anywhere from 19-23xxxLBs depending on weight

Hope that gives a little insight

tip select your plane on the flight plan setup page.. go to the map view and zoom out and notise the white circle.. when you change your fuel this sircle will indicate your max range.
But keep in mind you need example 1 hour extra fuel when you arrive at your destination for safety, and also head wind will make you use more fuel..

But the fuel range thing is a bit broken.. example the 787 dreamliner i fly from france to east usa and it only used about 20% of fuel for an 8 hour flight... that is a 4500nm flight
( i used 3x time compression so it too me like 2 hour and 150nm before i arrive game crash... ;-( )

Just saying its a bug... if i used the 747 i could barly fly the same distance without running out of fuel, and a friend of mine even had to cheat refuel since he had a strong headwind all the way.
( but it also depend on flight height, speed and weight how fuel efficient you are ).

I think fuel consumption for jets have a bug right now, but GA/propellar planes might be more realistic. ;-)

PS.. dont go on long flights yet, the game crashes rather often, wait a few days until next patch is released.

Great question, as a pilot this is something we have to actually pre-plan out and we refer to the POH, or Pilot's Operating Handbook that comes with each plane. We take into account the climb consumption to altitude, then we look at our cruising consumption (I fly a Cirrus SR22T so I know at 75% I use 16.4 GPH but when I climb I use much more than this since I am at 100% throttle).

Next we calculate what is referred to as Winds Aloft and using that information we determine are actual course and our actual Ground Speed. This is important because what you see in the airplane is the Indicated Airspeed, it could read 150 but with a tailwind that could actually be 170 or with a headwind that could be 120, so that's an important bit of info because I'll burn the exact same fuel in both scenarios, but one is going 50 knots or roughly 58 MPH faster than the other. From there we get our actual flight time and then we figure out how much is needed based upon the range we need to go and the time it will take to get there.

All planes have a standard range, but that range is rate for calm skies. You can extend that range with a significant tailwind or it will shrink with a strong headwind. So in reality you can't just sit and think, "Oh my plane has a range of 1000 miles so I can easily make this 900 mile flight." You could very easily make it, or a headwind could very easily turn it into an impossibility.

Now saying that, Delle(DK) had whats really the best answer for this. Look at the range circle and put what you think will work into it correctly and that will get you to where you need to be. Because it's a Sim and you don't have passengers you can pretty much always fill it up without a problem. Also you only need 30 minutes extra of fuel past your first landing, or 45 minutes if it's night time.

Hope that helps, pre-flight planning is a big thing for pilots and I wish there was a very easy answer on if you're going to X you need Y, but the reality is you need to do quite a bit of math to figure it out and even then once you actually fly your flight there is a good chance all of your preplanning is useless as the winds forecasted have changed completely.

I was flying the f-18 when the engines cut out. I had no clue what happened.
I tried restarting engines but not much happened. Then I noticed the fuel icon. The tanks were empty. Filled the tanks and the engines started. I took fuel for granted. Now I know better.

Is there a reason why the Beechcraft Bonanza won't touch the last 3.00 gallons left in the tanks? Auxiliary fuel pump doesn't seem to do anything and the engines simply cut out with 3 gallons left (6 total, 2 tanks). It's 8% of fuel capacity for that aircraft that's nothing but dead weight.

Some of what is in the tanks is unusable, this isn't a bug.

I'm not familiar with that plane myself in real life but ALL planes have what's referred to as unusable fuel, fuel that sits in the tank but will never actually be used. I fly a Cirrus SR22T in real life, it has a capacity of 94 gallons, but only 92 gallons are actually usable.

Now I looked up the Beechcraft Bonanza and found that it has a capacity of 80 gallons, but it's usable fuel is only 74, so that extra 6 gallons of unsuable fuel is actually accurate to real life.

Last night I went from Malta to Bogotà with a 787 and burn only 30% of fuel...
