If you need to get a King air B200 endorsement, you better get your cash ready, because it's not cheap.
Expect to fork out 15K with simulator time and 2 to 3 hours in the aircraft.
The glass cockpit version is nearly double that.
Throw on top of that, airfares, accommodation, meals, taxi fares.
Most of these king air endorsements, are company sponsored, in exchange for a return of service.
The Melbourne airports are your best bet to do the endorsement, you will find all the info online, followed by a phone call.
The training is intense.
