Ya but does it continue on to other destination? Because if I was to have a 737 just to fly 31 miles and return.... I'm thinking a rented car would do.

Not if you have some hundred people standing-by ;PNah, I agree, a bus would do, it must be for just moving the plane for its next mission.

Is there a way to calculate the optimum flightlevel for a shorter route at 300 nm or less in a Boeing 738?What would the optimum flightlevel be for a route at 130 nm again in a Boeing 738?

For 737-800 FCOM I PD.31.5, for example for air distance 150 NM, flight time 0:30, and expected landing weight 50.000 kg, the recommended flight level will be FL250, and for 50 NM, flight time 0:14, and same landing weight, the altitude will be 11.000ft.For another aircraft models you need revised the FCOM I Performance Dispatch Enroute section.See ya!

Thank you very much.

A car or bus might bea bit tricky. These are island villages. Flights are heading to Juneau or Seattle.

I suggest FSBuild. With it you can do this calculation by only entering ALT, and FSBuild calculates for you.

Oddly enough, I have never had to worry about this yet, as the FMS always spits out a usable optimum. If operating conditions dictate otherwise (like the use of lower airways on routes like FRA-CDG or something...), i just go with what it says, rounding down to the next correct FL for RVSM spacing on EAST/WEST or NORTH/SOUTH tracks, depending on the airspace in question...Fuel prediction with vroute is always accurate enough for me, giving me enough for alternate and 45 minutes min over destination...Andrew

Alaska flight 64 schedule is PANC-PAJN-PAPG-PAWG-PAKT-KSEA. http://flightaware.c...t/ASA64/history Overall time is below 7 hours with in excess of 4 hours stop time. The aircraft is a 734.

It will show a FL that is much too high for a short flight....

Why do you say that? The cost Index you enter is how you tell the FMC what balance you want between time in the air and fuel used - are you giving it the correct value for what you want to acheive?
