.....why is there such a massive disparity between the award of a PPL(A) and a PPL(H) for QSPs?
I negotiated the LASORS Section C1.5 definition some years after the accreditation scheme came into force. With no direct knowledge of the QSP(H) training course, I cannot comment upon RW training.
However, if you feel that LASORS Section C2.1 should be amended in line with C1.5, I recommend that you write a case and submit it to CFS(H) for support, then send it to CAA Personal Licensing Head of Policy for consideration. He might say 'no', but you'll never know unless you try, so what is there to lose?
