The list of Class Ratings, Type Ratings and associated requirements for differences training has been taken out of JAR-FCL 1 and placed in an admin document which is refered to by JAR-FCL 1. Makes sense not to have to amend JAR-FCL and follow the full NPA procedure just to add a new type.
There has not been any change in the requirements;
Differences trainng required to fly another single if it has VP prop, retractable gear, turbo etc as before. Once completed, differences training in SEP class aircraft does not expire.
Differences training is required to fly any other type of twin. If that type has not been flown in the past 2 years then differences training or proficiency check is required.
For the current list go to the JAA
www.jaa.nl and then choose "licensing" and then from the list choose "Licensing class and type ratings - list of aeroplanes"
