Odd question ref CPL(A) & (H) theory passes.
Hi all. I’m hopefully soon to finish my 14 ATPL theory exams and currently only hold a PPL(a). I am aware that the passes will be valid for the issue of a CPL(a) for 3 years. If I were to complete a PPL(h) during this 3 year period and decided to go down the commercial route in rotary instead would any of the ATPL(a) theory exams that I had passed be usable or would I have to sit the whole lot again using the (h) syllabus, thus having sat some 28 or so live exam passes (s’not appenin’ if that’s the case!). I am aware of cross crediting from one to the other but am wondering if this can happen with pre-practical TK passes or does cross crediting of exam passes only after gaining a CPL in one or the other disciplines.
