Share2care Chauderon Thank you for your reply.
I fly a Challenger 650 presently, having 9500hrs. Looks like all the Flight School are pretty busy and fully booked.
Will keep a closer look to Aerostar as it really seems that the "big" once also ask for big money.
When I read over the programs, it also looks pretty much like the CCC (Crew Coordination Concept) we had to do in germany already when i did my ATP in 1997.
