Also, MANY people work for companies with PC12 and other airplanes that are NOT a two crew airplanes, yet the insurance require unrestricted ATPL for captains positions. How do you expect those captains to obtained that? They can get an ATPL with ICAO restrictions, but like I said - they won't be able to fly to the US or Europe or even list a US alternate on their IFR flight plan, which is very restrictive.
Sounds like an AMOC to me OR one goes to rent a Seneca for the restricted ATPL.
