Odd one this. You must complete all required theoretical examination and flying training requirements before taking the CPL(A) Skill Test. As a QSP(H), you are credited 100 hours of the 200 hour total flight time experience required for the CPL(A); however, what is not clear is whether with 100+ PIC time on helicopters, you still need the 100 P1C on aeroplanes. Presumably whoever did your CPL(A) Skill Test checked first that you were eligible to take it?
Notwithstanding the above, P1 non-captain time in military aircraft counts only as PIC U/S for civilian purposes - not P1C.
Personally, I think that you should emphasise your total PIC (Captain) time, rather than seek credit for your PI non-captain time in the Hawk and Tucano.
So much easier when the RAF training system gave trainees more solo time....
