ATR type rating covers which models?
I just got hired as an ATR Captain in a ATR 42-320. I have been looking online but can't seem to find information on what variants of the ATR this type rating will cover? Is there only one type rating for ATR 42/72 and then differences training for -500 and -600 or does the -500 and -600 require different type ratings? If you have the answers and can point me to your resource that would be a big help also. I will be operating the ATR in the USA but looking toward future employment overseas. Thanks a lot for all the help. This forum is a huge asset for pilots.
