I guess from your comment " take off is interesting" that you fly modern jets?
The Belfast at MTOW (231000lbs) in temps around 31 degs C is just on its WAT limit at sea level and 1013mbs. Water Meth is injected into each engine to keep the power up to ISA levels (about 5750 SHP!) She really is on the limits and must be flown very accurately in the event of EFTO after V1. When allowed we used to practise such things at a minimum of 10000lbs below MTOW; we had some very interesting comments from various International airports, most who thought that normal take offs were exciting enough!
In fact the planning involved for a flight with terrain drift-down problems and ambient temps much above ISA was considerable; every leg with a MORA or MEA much above 10-12000ft ( and lower immediately after t/off) had to be closely scrutinised, we freqently had to climb in holding patterns.....a vastly different world to that known by most wide bodies! Fortunately with Pacific flights they shouldn't have too many of those problems out of Brisbane.
I know the crew very well and two of them for over twenty years of operating the Queen! It was an exciting and rewarding career, we visited most disasters and war zones in those days.......but that's another story!
