I'm going the other way at the moment. For the JAR CPL(H) the only ground school I've got to do at the moment is the principles of flight. The flying consists of 135hrs TT to get the CPL. Dispensation of 50 Hrs. There are currently NO bridging exams, but they may be around next year.
This is all dealing with the U.K CAA who have been worse than useless. When asked for a simple answer to a simple question. e.g "As a fixed wing instructor do I get a dispensation on the no. of hours required to get an FI rating on a heli?" So far I've had 5 different answers. They can't even agree on the wording of FCL 2.
Good luck with them and let us all know what they have said.
