Assumptions:
50 passengers with 30kg of baggage
500 kg freight
So, assume a payload of 6,000kg
Could a 747-400 fly from Brisbane to New York Direct with the above payload?
Yes, I think so but it could be tight! Hopefully your aircraft will have the Stab Tank fitted
What would be the average cruising speed with that payload? ( have seen everything from 413kts to 525kts quoted).
Long-Range Cruise is M0.85, so about 500kts in ISA
What would be your best guess with prevailing winds for a mid March flight of the ground speed/flight time?
Assuming 490kts avg ground speed, about 17hrs30mins
I know the last question is at best a wild guess but I am hoping some experienced guys or girls on here may be able to provide a ballpark figure.
9,000 hrs/14 yrs on type
Last question, what is a 747-400's max cruise speed, where fuel burn is not a consideration, with 200 pax and over no more than 3000nm?
M0.90/520kts
Quick answers so my best guesstimates. Sounds like a fun project. I have manuals and planning info available. If you would like more detailed information, PM me.
