CJ Driver,
Whilst it is an interesting academic discussion, in reality only people flying very short sectors are likely to be limited on a OEI missed approach.
I beg to differ. Try taking off at sea level, flying for an hour, then landing at 1700ft AMSL at 40°C at max landing weight. This issue then becomes bigger than Ben Hur.
If you're doing 10% OEI (~1200fpm?), then you either don't have much fuel, don't have many pax, it's bluddy cold, or your engines are too big!
