Fixed wing to Rotary
 

Does anyone know the best way to convert fixed wing to rotary licenses?. . I have a JAA PPL(A) and an FAA CPL/IR(A) +256hrs. I'm due to start at the Guildhall to do the ATPL theory in May, what extra theory exams would be needed for a JAA CPL(H). Also what extra would I need to do to get an FAA CPL(H)??. . I would like to do the ATPL theory then go to the states and instruct both fixed and rotary, then come back and do both CPL flight tests, or am I making too much work for myself??. .. .Cheers
