I must admit i think its a good thing if they stipulate a min time on type. But it's going to annoy alot of CFI's who will try and pass the cost onto the instructors. Something to think about while hour building for people who know they will be wanting to instruct before heading on.
On all my checkouts on new types for various schools its been maximum 3 circuits. Then away with students, wasn't to happy with it but you don't really have much choice if you want to earn some money. In fact i was only ever checked out on new types never on the ones i had already flown even if I hadn't flown them in over a year. And DFC is correct there is no way you can learn a machine in an hour. Unfortunatly most FI's the first time they spin a new type its with a student sitting next to them. Mind you we don't have instructors killing themselves all the time so maybe its not required its usually the experenced ones who have the problems
I always found the C172 a completely different beast to the C150,152 and the particular onei used to fly it must of taken about 30-40 hours of trial flights before i could place it exactly where i wanted it and stop it flying at the same time.
