Does anyone have any good sugestions as how to plan your fuel usage for a 747 flight. Say for example, London - Chicago or London Newyork?I was under the impression that Chicago was near the 74s limit, but I was wrong, according to the POSKY 2004.8.5 FDE with a full fuel load of 360K it has enough fuel to fly there and back!

You can use the fuel planner from the PSS 747. It is in the library here:http://www.avsim.com/pss/manuals/fuelplanner.zip

"I was under the impression that Chicago was near the 74s limit, "Hi,From Europe, Chicago is about 9-10 hours (depending on where you leave in Europe). The B744 has an endurance of more then 14 hours (that's the KLAX-YSSY flight time, which is flown non-stop by the B744). KLAX-YMML (also a B744 non-stop) is more like 14 1/2 hours I believe, although Qantas may use their B744ER on this, I'm not sure.The latest Flight International (larger Farnborough edition) has details of a possible stretch for the B744, using the 7E7 engines (with air bleed mods).Bruce.

Just to show an example of todays ultra-longhaul (New York - Singapore, A340-500. Distance 16.668 kilomers, flight time 18 hours, 35 minutes (all data approximates that change). Check the thread for a map of some of the various routes:http://aerowinx.com/forumh.cgi/noframes/read/12520

In real life I've flown on a 747 LA to Sydney, which is about14 hours non-stop & we still have fuel for another hour or twodiversion.Peter Sydney Australia
