It climbs with full load up to 7000fpm up to 10000ft and than with up to 4000fpm to 16000ft. unfortunately from 16000ft the performance of the props start decreasing due to the density.
Crap.
Full load up to 7000ftpm? A fully loaded Q400 would be pushing 2000ftpm to 10,000ft on a good day. Even an empty Q400 Doesn't get 7,000ftpm at sea level.
First yes Qantas or South African express is flying in limited areas, still serving on an entriere continent to do not see a lot of different weather.
I think you underestimate the weather in either of these countries. Yes they may not spend much time covered in snow or ice, but when was the last time you saw a squall line stretch 800km? Europe has some fun strips, but they are surrounded by full ILS alternates.
I like that you are standing up for the TP guys, but your argument has some stunning holes in it.
