Turbine for commercial ops, charter etc is fine, but there is a no choice for the private owner who has a different set of requirements. The private GA sector grew on aircraft that could haul the wife and 4 kids plus all their gear, surfboards, bikes etc, perhaps even the family dog. Most of these owners flew very short sectors, often as short as half an hr.
The Baron, Seneca and Aerostar, all great aircraft are too small.
The C208, PC12/King Air etc while fantastic aircraft, lots of start cycles on the engine will make it horrifically expensive.
Not to mention the bank runners who can do 4 hrs a day but with up to 20 hops.
Its seems a whole sector of the industry is being ignored.
