To exercise the privileges of a LAPL for holders of a PPL
The following change in Switzerland will apply from 1 July 2020.

With the adoption of COMMISSION IMPLEMENTING REGULATION (EU) 2019/1747 of 15 October 2019 amending Regulation (EU) No 1178/2011 as regards requirements for certain flight crew licences and certificates, rules on training organisations and competent authorities, PPL licences include now the privileges of a LAPL licence during the rating validity:
FCL.205.A (a) The privileges of the holders of a PPL(A) are to act without remuneration as PIC or co-pilots of aeroplanes or TMGs engaged in non-commercial operations and to exercise all privileges of holders of a LAPL(A).
FCL.205.H(a) The privileges of the holder of a PPL(H) are to act without remuneration as PIC or co-pilot of helicopters engaged in non-commercial operations and to exercise all privileges of holders of a LAPL(H).
As a consequence, a holder of a PPL, CPL or ATPL may continue to exercise the privileges of a LAPL during the rating validity, for example in cases where he only holds a LAPL medical, provided that the recency requirements are met.
