My only concern about having a seperate NPPL and JAR PPL instructor rating is as stated in my previous post.
I would be totally happy to see a change which permitted renumerated instruction given by the holder of a PPL, as used to be the case prior to the introduction of the BCPL. Indeed a number of the instructors who taught me during my PPL training in 1987/8 were PPLs and three of them still instruct and examine with a restricted BCPL. The fact that they have never passed the ground examinations for a BCPL/CPL/ATPL has no effect whatever on their instructional ability.
I have instructed full time for over eleven years and hold a CPL/IR and I fail to see how that makes me any better or worse an instructor than those of my colleagues who hold a restricted BCPL. For those who dont know the restricted BCPL was issued without formality to those who used to conduct renumerated instruction on a PPL.
