Fuel Calculation with B727-200ADVC

[zakard]

Hi!
first of all I wanna thank you for you fantastic work. I love to fly your aircrafts!!! I think it's the best freeware work I ever had (and also surely better of other non-freeware aircrafts I bought ahaha).

I got a question for you: how can I calculate the ammount of fuel to take on board for my flight, expecially w/ B727-200ADVC and B727-200F ADVC? I haven't found any fuel-planner, neither formulas or things like that, but maybe I'm a little "blind" !

Thank you very much again, and my best compliments for your work

ciao!

According to an article in a magazine I have; 727's burn around 3000lbs per hour per engine.

That is the figure I use when planning my flights, and I haven't run dry yet

"EMPRESS" is quite right !

3,000 LBS per engine per hour is a good ball-park fuel burn figure to work with for the B727's .... depending of course on the engine marque, and other fuel burn influencing factors too.

"IF" you would like to take time to refer to my "B727 PANELS INSTALLATION & HANDLING NOTES" (appearing on the "ABOUT HJG AIRCRAFT" forum page) .... then on the end of this thread you will find my "B727 FLYING GUIDES" (for each B727 aircraft/engine type) and which do record FS fuel burn at FL310. I must stress that these obvservations recorded are not realworld data and merely represent FS performance .... and despite the fact that these indicated fuel burn observations actually are very close to reality for each aircraft/engine type represented here.

Also .... if it helps .... here's a very basic methodology I use within FS in order to determine fuel loading for each of my flights ....

Don't laugh at me when I suggest this .... but .... I use a very crude methodology of fuel planning/calculation which always seems to work fine for me.

I simply multiply any aircrafts indicated cruise "fuel flow per hour" figure (per engine) by the number of hours my flights along any particular route are estimated to take .... then add between 30 minutes to 2 hours reserve .... with an extra 10% on top of that too just for good measure.

For example .... with our original DC8-10 (not the current one with corrected fuel burn rates) I used get cruise "fuel flow per hour" readings of around 6000 lbs per engine at around FL310. Multiply this particular fuel burn figure by each of the 4 engines and that then equates to some 24,000 lbs of fuel spent per hour.

Therefore .... if I fly from Auckland to Christchurch (which is just on 1 hours flying time) .... I typically loaded 24,000 lbs fuel .... plus an extra 30 minutes (reserve) which equates to 12,000 lbs .... for a revised total fuel of 36,000 lbs. To that I then add another 10% of this total which accounts for an additional 3,600 lbs of fuel .... and which then equates to a total fuel load of around 39,600 lbs fuel on board for the entire 1 hour flight .... and which I then distribute evenly among each of the number of tanks provided in each aircraft type.

Using this extremly crude methodology (fuel flow figures are different for each engine/aircraft types so you do need to experiment) I've never .... ever .... had everything suddenly run "quiet" on me en-route to any destination .... and nor have I ever had to declare an emergency and divert to somewhere else where I wasn't planning on going either just in order to top up.

By these means I've always arrived safely at my planned destination with a comfortable fuel quantity remaining after shutdown and without being overweight for landing either.

It certainly works within FS !

Try that methodology .... just for fun !

Thank you very much! It is just what I needed to know
