what annoys me is the subtle changes in wording. For example The holder of an ATPL still holds a Commercial Licence and a Private Licence or at least always did. Some of the wording in particularly in Medical regulations may imply we don't, even though I don't believe that is the intention of it.
So reading the Medical regs alone can the holder of an ATPL fly his Kingair in private ops on a class 2 medical certificate with 10 people on board.
