I've added in Mutt's figures and updated the table which is shown below. Mutt's figures for the 747-400 equate to a 747-400ER, 340 tonnes, ISA +17 deg C, PW4062 engines, sea-level airport. For 2133m runway, that allows 220,000 kgs OEW + payload. That means up to 370 pax @ 96 kg/pax (after making some assumptions about empty weight). That’s good for about 5200 NM range in nil wind incl. reserves. Factor in the commercial reliability factors of 85% winds on an west-east-west routing, and a bit of extra holding, and it brings the dependable range down to about 4,200 NM. The revised table is now:
Code:
AIRCRAFT Normal  Hot_high ShortRange  Extreme
757-200                               990
737-200  2300m    2600      1800      1300m
737-400	                             1450
777-200	                             1550
767-200  2600     3000      2000      1850
747-200  3100     3600      2600      2072
747-400                               2133
