Re: Ezy Pan at NCL
It's well known by Boeing - they cover it with a procedure in the manuals! Not overly common in Europe tho' as it's only gonna be utilised in very hot and short or high airports and then only when the APU is U/S IMHO....... 
Oops...... memory not gettin any better these days - and will be practised by guys exposed to similar circumstances as these and who have read this thread ........ and of course "know it alls" hehe!

Epsilon - be careful of course! That's what we are paid for...... We are also paid to make correct and considered decisions and back them up with careful actions. Thanx for yr concern though.
By the way - there is a huge gulf between planning something and an accidental occurence - we would all do well to remember that!

Epsilon minus:
Yes and we had two crews with oxygen masks on calling Mayday just after take-off with serious fumes and smoke in the cockpit which resulted in very rapid returns to earth!
There has been no further problem since we abandoned using APU air after deicing.

Loc Green,
I do realise that but in the A320/1 we can land upto max landing weight for any return or diversion whether the reason is minor or major (LDA permitting) I would have thought a 737 would be the same but have never flown one, hence my question.

On the Airbus in EZY, all take-offs are unpressurized as it preserves engine life. Due to the aircon packs being switched off, the EGT on each engine reduces and therefore reduces maintanance costs. An added effect is that ofcourse with packs-off you have an increase in performance.

We used to do a number of bleeds off t/os in the 737 200, not as much in the -300. Did more in the A1 powered A320. LAS in summer going to JFK in 40 degree heat (C) required bleeds off. And the APUs are crap on the 320 so half the time it was unpressurized. No worries in the 757. We can do reduced thrust off the 19s (short runways) in LAS with a full load to the east coast up to 42C.
BTB - what type of deice fluid did you use? The type IV fluid that is used here in the States is a lot thicker than the old type I glycol/water mix and is designed to shear under airspeed load. The sh## gets into everything. The F/O called me down to the ramp the other day in San Diego to look at what appeared to be hydraulic fluid coming off the flap canoes and aileron leading edges. Turned out to be deice fluid from days ago that mixed in with humid air on the descent and leaked out some holes.
