FCL.110.LAPL(A) - Experience requirements and crediting, inherited from EASA:
(c) Crediting. Applicants with prior experience as PIC may be credited towards the requirements of point (a).
The amount of credit shall be decided by the DTO or the ATO where the pilot undergoes the training course, on the basis of a pre-entry flight test, but shall in any case:
(1) not exceed the total flight time as PIC;
(2) not exceed 50 % of the hours required in point (a);
(3) not include the requirements of point (a)(2).
Point (a) being the minimum total & dual & solo time. This is PIC time, so 16.5 hours dual & 30 mins solo doesn't really count for much.
