As presumably would the practice of towing aircraft to the holding point where they could start engines just before TOGA, hopefully allowing the requisite warmup time?
And I have yet to receive royalties for the bleeds off, packs-off, 1st pack on at 10,000ft, second on at 25,000ft procedure which I invented some time ago, when not quite myself, following discussion in the forum on 'bus unpressurised take-offs.
That in conjunction with 1st pack off at 25,000ft in the descent, followed by the 2nd pack at 10,000ft all finished off with a flourish by coasting onto the stand should save MO'L and the rest a real packet of fuel and therefore costs.
These fuel saving methods are presumably "legal", but are they safe and sensible?
I'd like to be a fly on the wall when it's proposed to the CAAs various, though judging by their recent record on (lack of) supervision and apparent subservience to BigCorp, they might even be actively considering the procedure?!
But I still claim the royalties....................................
