just landed in YSSY. Flew YBAS to YSSY route. b727-100 modded.

http://fuel.aerotexas.com/ - this fuel planner said i will need around 26200 lbs for flight. and i really used this amount of fuel. good UNIVERSAL planner, many planes presented, but unfortunately it is not detailed. you cant fill cruise FL and so on. and it needs dep and dest ports to be entered. many regional airports not there.

To take of from 8000 ft rwy 30 at YBAS i had to be at TO weight no more then 150 000lbs. so i loaded 12000 lbs cargo + 114 passenders + and 32400 lbs of fuel. fuel planer suggested 39000 lbs with reserves, but i canceled fuel for diversion (bad idea). i landed with about 2600 lbs in every tank. climb wasnt fuel efficient (again), but still better then my worst climb. i used 7600 lbs for TO and climb, versus my best 5500 with same TO weight. during cruise i monitored fuel usage every waypoint (NDBs, VORs), and throttling back a little to set cruise pwr for current weight. Descended at idle, and landed YSSY rwy 16L. And that way i was able to get very close to EFU by that planner. really need to know more about fuel efficient operations :) Usually i overusing fuel.  but i better learn about all that :) I wanna go Hawaii in 707 :) dont want to swim around floating wreck of my x-mass gift to myself somewhere in pacific :) Thats totally uncool.
