Posted: Wed Dec 19, 2007 10:51 amNot sure weather this has been asked before, but does anyone know how to calculate fuel for a specific flight, or a tool that does it for you.
Thanks

Ok what about reserves, how many hours extra? 1 hour?
Thanks for quick reply
Posted: Wed Dec 19, 2007 11:28 amDoes 6,000kgs/hour sound about right for b767? Only article I could find.

Posted: Wed Dec 19, 2007 12:07 pmWell assuming you have a flight plan:
you'd select your aircraft, click on "Nav Log" and get some flight details:
This one is for an A380.
A SIA 260 would tend to use a little less fuel, but may need a stop or two:
You might repeat the exercise for your divert airport, plus 30 min reserve.
Quick calc for the Airbus above shows 6,000gph so add 3,000gals.

Posted: Wed Dec 19, 2007 12:15 pmSorry Charl, but you cant trust the FS9 Fuel Planner.. 
Yes, It depends on your alternate. I normally carry around 1 hour extra fuel..

Posted: Wed Dec 19, 2007 12:21 pmI usually just chuck in what seems a good amount, I usually just fly regional routes so it's not so much of a biggie for me. For example, in the Beech I just chuck in 35-40%.

Yes I'd heard it wasn't too reliable, but hey, it's a flightsim:

<alt>/A/F
Top up tank
<Unpause>
Land as if nothing happened, just make sure no-one was watching the middle bit...

Yup same here, usaly makes it with about 15% spear

Hahaha yea, works well huh?

Posted: Wed Dec 19, 2007 3:48 pmWho Plans fuel in a B1900D anyway
Posted: Wed Dec 19, 2007 3:49 pmAnswer from a B1900D captain (RW) when asked about how much fuel they had on board: "Oh plenty, no worries about that!".

Posted: Wed Dec 19, 2007 3:56 pmOr even better guys
Nick, search "FUEL" in the "FS2004 Utilities" category ONLY at avsim. You'll get a fuel planner for just about anything you want to fly.

Posted: Wed Dec 19, 2007 4:24 pmThanks for you replies, I did download a fuel calculator for the 737NG for free, which looks all very fine, and am testing it out now on the ML - PH route.
So will see if it is accurate or not in about 4 hours

Posted: Wed Dec 19, 2007 4:26 pmIf you are using the PMDG, they have a fuel planner on their site for their 737 range and it works well

Posted: Wed Dec 19, 2007 8:15 pmIt's somehow never been an issue in the sim for me, as I said I cheat if I messed it up.
I do remember some discussion way back about the accuracy of FS fuel calculations.
Does anyone know how inaccurate, and if it's consistently inaccurate or depends on distance or aircraft type?

Yes thanks for that link, already had D/L though.
I think it might have worked properly, if only I had have told it to compensate for 100 knot headwinds!?! (this is the info the FMC was giving me anyway) Is this correct? 90-100 knot headwinds the whole way and 10-15 knot crosswinds. BTW I had real world weather on (YMML-YPPH)
