Farkin hell you guys complicate a simple thing.......
Times the track miles by 3.......
It's 8nm. 8 x 3 = 2400 feet. Runway 34 is 330 feet AGL. You're actually 2100 feet agl at sheed.
The only time it gets difficult is if you DON'T keep driving it down, and you turn into melbournes legendary winds on final, ground speed mini kicks in and the engines spool up just as your trying to drive it down......
It can catch out young and old.
Now back to how a senior Qantas captain buggered up a simple approach, how it's Jetstars fault for giving their crews a pay rise and how life is so unfair when there's nobody left to blame but yourself.....
