The ATR isnt that tricky to learn. Its systems are a little differnt cause its french and they used different names for things like auto feather-they use ATPCS. The instructors are great very expirenced, helpful, and can actually teach. There is no room for error in the sim so be ready for it. You can screw up a bit on the first day of a new subject but you better know it by the second. You also have to go swimming and get into a life raft for the training and that was fun.
