distrance traveled

[Eruthian]

Uhm...do you mean the overall fuel you used, or the amount of gallons per hour in specific phases of flight?
Wouldn`t you be able to do so anyways, by monitoring your ammount of fuel on board ( fuel indicator), your fuelflow indicator and compare that with
your flightplan? I`m sure it`s not that easy to do in a Jet (I`m a Jet noob, just that you know^^), but especially on my Jetstream I do that all the
time, especially on "long" routes, which reach the edge of operational range.
It`s no exact calculation ofc, but it works pretty good so far.

Let`s say I`m on one of my standart routes from PANC (Anchorage) to PADK (Adak, Aleuteans)
The distance of the route is arround 1070 NM my choosen FL is 180, planned flight time is 4h.
I normally load 80-90% fuel depending on payload so let`s say 5400 lbs in this case
After departure it normally takes arround 10 minutes to get to cruise altitude and then another like 5 minutes to reach a cruising speed of arround
290-300 knots ( real airspeed) at 18000 feet At that time, because of the Sid, I normally just passed my 2nd waypoint and have arround1050 miles to
go, means arround 970 miles at cruise altitude. Departure and speeding up at FL takes arround 15 min, the taxi arround 5 min, so I have 3h 40min left
to get to the gate at PADK. For the last 70 miles of descent and approach aswell as taxiing I normally calculate 30 min. So I would have to fly
arround 300 knots to reach the airport right in schedule.
Now comes the fuelplanning. I started with 5400 lbs. To make FSP happy and to keep it real, I want at least have 800 lbs remaining, when I shut down
the engines in PADK. During takeoff and climb, the plane burns alot of fuel. Between 1400 and 1800 lbs/h. So arround 300 lbs are already gone, when
I`m at cruise speed. 5400 - 300 - 800 = 4300lbs left until shutdown.300lbs I spare for descent, approach and taxi(normally it`s less anyways). So 4000
lbs are left for the cruise. The cruise of 900 NM with 300 kn takes 3h. In that conditions I can get the engines to use arround 1200 lbs/h. So I`d
still have 600 lbs to spare for go arrounds or to divert to an alternative airport. Or ofc to throttle it up if winds change, to keep the speed - and
make oil industrie happy about my waste^^
I tend to recalculate that every 10-20 min in flight to adjust if needed.
Might not be the most economic way to fly, I know. But as long I make the passengers happy and can fly right in schedule without fuel penalty, I`m
fine. In the end it`s still just a Sim
A 737 or bigger might be more bitchy to plan with though...^^
