Fuel Planning

"I have rather odd question, I attempted one of my bidded flights PAC703 KORD to RJAA to RKSI, and realized within the first third of the flight the fuel load I had onboard (BTW I flew with full tanks in the RFP 742) would either barely make it into Narita or run out on on the final legs of the flight. I used a route generated from <a href=""http://rfinder.asalink.net/free/"" target=""_blank"">Route Finder</a> which indicated a 5600nm trip. I loaded the RFP 742 with only 51000 lbs of cargo as well can the 747-200's make such a long flight with out a fuel stop?? Or would they plan to re-fuel in Anchorage and continue on so they add more freight for the flight. Secondly, how do we record we are plannig a fuel stop along the way. I also am flying a flight from KLAX to RKSI this week as well and the same problem will undoubted resurface itself."

"Mike, those are long trips, I usually stop at panc, for fuel, breaks up the flight nicely. Just do it as 2 legs, (log 2 separate flights)Then you can carry a little more load if you want and make more money for the company. I think there is a post somewere that it is more effecient to carry more load and stop for fuel, than to try to do it all at once and carry less load. I think i tried to do klax to somewere in asia last year, all in one flight, there are some worried moments at the end of the flight, but you can cheat a bit by adding a good tailwind :rolleyes: I have a 2nd leg of an atlas charter to do ksea to rctp with 101000 lbs load, i am still trying to see if i can do that i one leg. May have to stop at the north end of japan for fuel, we will see ed mosier 1287"

"Fly those KORD routes at M.79 or so, and do your step climbs, and you'll be surprised at how much fuel you'll have onboard when you arrive. I've never done the Los Angeles to Shanghai run."

Thanks for the tips. I made the trip from KORD to RJAA nonstop. 51000lbs of cargo and pretty much full fuel tanks. I guess I must have been screwing up my step climbs and cruise speeds. the flight was flown after my first step climb from FL260 to FL300 at mach .82 with a final altitude of FL340 but still at mach .82. I saw the real Polar 703 uses a 747-400 and flew at Fl380 for the trip on Flightaware. Again thanks for the tips.

"Mike Just finished a 10 hr flight from Liege to Narita in Japan in the 744, 5000+ miles with a p/load of 174000 +lbs and a Fuel load of 346000 lbs, nursed it along, didn,t get to cruise until 2/3rds of the way running about .81 mach, landed in Thick Fog and just got onto the Stand when the engines stopped, out of Fuel ,it pays to have a fuel stopover ! :blink: Mike :wacko:"

"I have no experience on the 747-200, but it looks like you loaded to less fuel. Normally for such a long flight you should be loading about 300,000lbs of fuel. By the way, I´m curious about how you plan your step climbs in the 747-200. In the -400 you´ve got the FMC, but the 742 ain´t such a thing. Please help me out, jeje Greetings Juan Carlos"

Juan Carlos, Michel's excellent <a href=""http://globecargo.ipbhost.com/index.php ... ost&id=543"" target=""_blank"">flight planning document</a> that he posted a while back has a section on it regarding optimum cruising altitude for your current gross weight. Have a look at this to help you out with your step climbs. Mark"
