Accurate Fuel calculator - pdjpeter - 16-02-2006
Hi does anyone know where i can find a accurate fuel calculator? because i did a flight last night and the FS2004 navagation log told me xxxx pounds
of fuel so i went to fsp put in that amount plus more for reserves but then plane didnt make it to the destination it was ages away.
so does anyone know where i can find a accurate fuel calculator?
thanks

thanks but does anyone know of a freeware one?

There are a few fuel planners on http://www.AVSIM.com for different aircrafts. Try searching for "fuel Planner" under "utilities" and "miscellanious files".
I also found one once that included multiple planes, but can't remember where I found that.

Just found it here http://www.simviation.com/fs2004utilities7.htm
It's the second one from the top. I haven't tried it out myself so I don't know how accurate it is.

I found that FSNavigator is quite accurate, once you do some research on your aircraft (using FSpassengers).. Each flight, look at the
climb fuel used / time of climb, cruise fuel used / cruise time, descent fuel used / time of descent.. do the simple math for lbs/hr plug
those into FSnavigator on the aircraft data page... It will then predict your fuel quite accurately.. it will do it accurately enough if you just
take the fuel usage per hr from fspax's aircraft stats page..

Since I have bought a few Aerosoft products, lately they give you a free copy of the flight planner with the purchase which is a nice deal

Where can I find a Flight Time Calculator
Re: Accurate Fuel calculator - Usty - 21-02-2006
When I have a new aircraft, I make a test flight.
in this flight I take my avarage speed/hour and fuel flow..
I calculate with these numbers in ms.excel
I take the flight distance, times the FF/h.. that gives me the total cruise fuel excl. reserve.
then I usualy take 1 hour reserve (FSP requires 45min.)
and some taxi/apu fuel. (sometimes up to 30 min's fuel for large airports!)
when I fly at difrerent speeds/altitudes, I estimate my average speed, E.g:
with the fokker 100 I fly 300kts average gs with a total of 500kg/h fuelflow. (sorry the metric numbers)
on a short flight I calculate with 200 kt's.. on a verry long flight 350. or even more.. (depends on flightlevel and on a short flight the
departure from ATC is a greater part of the flight)
(on max. cruise flight the t.a.s. is around 400kts in no wind cond.)
when I expect winds I calculate these in percentages to the flightspeed. e.g. when I expect 20 kts head wind that is on a short flight 10%
of my average speed. so I take 110% of my calculated cruise fuel.
that is on the short flight of 1.5 hours (EHAM-LSGG) with the Fokker 100 (numbers are fictional! I am at the office! :P)
1.5 times 500kg/h = 750kg. + 10% wind correction = 825kg.
30 min. apu and taxi = 250, 1 hour reserve = 500
that would be a total of 1575 kg fuel on my flight
I take for schiphol 15 minutes taxi and 5 minutes for Geneva cointrain. and 5 minutes SID/STAR flight. therefor my b/b flighttime is 1hour
55 minutes. (note that the startup time is before the b/b timer!)
this works great for me! I use the MS gps to correct my ETA (on modern aircraft) and I closely monitor the inflight fuel preditcion
(though the fokker 100/70 has a good fuel monitoring system itself)
when you fly the same route more often, you learn to know your aircraft better and correct your own error.
within 2 or 3 flights you have the perfect fuel calculation..
I hope this works out for you as good as it does for me.
happy landings!
Regards.

Re: Accurate Fuel calculator - olseric - 21-02-2006
I like Usty's method. The best fuel calculator you can get is using pre-recorded data from your own testing due to the inconsistancies
between FS aircraft and real-world data.

Here's a really excellent one for PMDG 747:
