Until the madness of EASA is sorted out, I suggest that you consider the NPPL(SSEA) as an option.
All NPPL credits available to UAS pilots remain in place. See
http://www.nationalprivatepilotslice...20REV%2009.pdf page 5 / 23 or CAP 804 p 727 / 794. Once you have an NPPL (SSEA), you will be able to convert it to a LAPL(A) before 8 Apr 2015.
Once you have a LAPL(A), you will be 'in the EASA system' and able to convert it to a part-FCL PPL(A) under the terms stated in CAP 804 - the same as for any other LAPL(A) holder.
This convoluted process is necessary due to the inferior levels of military accreditiation now offered for
direct application for part-FCL pilot licenses than were available hitherto.
A pity that UAS flying is now so sparse. I note that in my first UAS year I gained 39 hours, to add to 35 achieved on an RAF Scholarship and another 7 I'd managed to scraped up enough money to pay for before joining the UAS.
