PA-31 v TBM
Maria,
I only base my comment on the 3 years I spent flying chieftains - we were either chock-a-block or, more often, carrying only 3 or 4 pax.
If it was an internal corporate flight it was, 95% of the time, with only 2 or 3 passengers. If you look at the accidents which spawned this thread, they too only carried 2 pax each.
Corporate Av is all about TIME - just check out the emphasis of the recent advertorials in Aus Aviation and US Flying. I aint an expert but in my experience that is about the size of the market and if you want to do it with a turbine, go the TBM! It's a big step up to the PC-12 and if you are going further than 200nm the Van loses its appeal...
regards
