Even after a dozen simulator sessions converting onto a new type, it's not like a simulator. It's still becoming 'familiar' and it is a very nervy anxious time. When I first flew a real 737 glass panel -400, after takeoff I sat back and let go at about 4000' in the climb. The plane started gently rolling not doing at all what I wanted- I'd neglected to actually engage the autopilot. Familiarity comes quickly in the real aeroplane, but I found simulators didn't fully prepare you although they get you 95% there. With 'zero flight time' conversions, there is no circuit bashing in real aeroplanes- the first time you fly a real one is on normal passenger services, with a special training pilot to help you get into it! That first landing does tend to be a nervy time!
