I didn't realise that a two bottles per wing option existed on the 744.....
That's interesting as I never knew a 2 bottles per engine option existed ether. I'll try to copy and paste the schematic from my FCOM.
How long would one expect to be held/taxiing for at peak time in HKG as a matter of interest?
From the freight ramp, I'm usually airborne within 10-20 mins at HKG.
1500KG for 10mins taxi seems a lot
Quite correct, I should have said 20 mins. typo.
