Hello! I'm looking for a good program I can use to determine the duration of a flight and how much fuel will be required in FS 2004.
Anyone know of anything, or a feature in FS that does this that I don't know about?

Simple. Find out the average fuel flow of your aircraft per hour, work out the length of your flight, load the required fuel, then add an extra hour's fuel for reserve. Of course there's a bit more to it than that but you know what I mean.
Basically, fuel flows (avg) I use on FS are these:

While in midflight, esp on longhauls flights, heres what i do to fig out if I'll have enough fuel for the remainder of my flight.
Pull up your clock and start it for one minute-to the second. (ie-8:44:07 and stop it at 8:45:07)Giving you 60 seconds.
Write down how many lbs of fuel is left in the tanks.
You will see how many lbs of fuel burnt in the 60 seconds.
Jot down your FF per hour, mileage to destination and fuel left in weight., BEFORE & AFTER.
#'s are examples: 7,900 lb/hr (times 4, for a 747=31,600lbs/hour or 526.6 lbs of fuel per minute)
8 miles traveled in 60 seconds, and 4680 miles to go till destination /by 8miles per minute=585 minutes.
287,900 lbs of fuel in the tanks. OK, stay with me. Divide 287,900 by 526.6 min's=547 minutes. Guess what? I need at least 585 minutes of fuel so I'm short by 38 minutes. But, I have plenty of time to throttle back and use less fuel and I'll make my destination without "cheating" to add fuel.

If the quoted requirement is less than 100,000 pounds, double. If more, multiply by 1.5. Has always worked for me, but a lot of times the reserves get used. I also don't fly very long legs. 1500nm is generally my maximum length.

But what about more fuel efficient aircraft? or is it just a general thing your using there? also what altitude is that based at?
