btw. just to confirm, I calculated if a B744 can takeoff from 1900m runway with all 430 pax onboard, to a short <2 h flight:
- 1,5h flight requires some 14tn (kg) fuel, assuming reserves are 5.0 tn, we'll have total fuel on takeoff 19000 kg.
- Empty weight is about 180 000 kg.
- 435 pax á 95 kg (pax + bag) brings in ~41500 kg.
=> Total takeoff weight is 240500 kg.
Then looking at the B744 takeoff performance chart (assuming pressure altitude 0, 0-wind, ISA conditions and for example CF6 engines), I will get the lowest possible takeoff rwy requirement for this aircraft which is about 1770 meters.
So in other words, yes it can, and there's margin for adding more weight (= fuel), if you see the green line on the chart.
