In 2007 I gained an NPPL(SSEA) after a break of 27 yrs flying.
As an ex Qualified Service Pilot with about 180 UAS & EFTS Chipmunk and Bulldog hours, I was regarded according to the rules as a PPL lapsed over 10 yrs.
I therefore had to do the complete dual and solo nav syllabus, as much dual and solo GH as I felt I needed, the Nav test, the GST and all of the theory exams.
Total flying time to license was about 21 hours in a PA28.
Added a microlight class rating in 2009.
