Hello. I am considering getting a type rating for a Cessna Citation, for the experience, and also to make me more marketable to the airlines. I was looking at the program that ATP has. Its a 4 day program. 1st day is ground, 2nd is ground, sim, & flight. 3rd is ground, sim, & flight. and 4th is a checkride. They send you Training material before you start for you to go over. Being where I am at right now. Commercial Multi-Engine Instrument Pilot, with about 550 hours, and 100 hours multi, will it be pretty difficult to do such a rating without any previous Turbine time? I am pretty determined in aviation, and when it comes to learning something new, I could do it all day and all night. But the thing that concerns me the most is stepping up from a Beechcraft Duchess that cruises at about 140 knots straight to a Cessna Citation which I am assuming has an approach speed somewhere close to 140 knots. Anyone have any comments, tips? Thanks in advance.
