Hi, Hegemon88
First, well done for having read the whole of CAP804!
It was originally intended that each Licence would include the privileges of all the Licences below it, in the same Category, and that you would be able to use any Medical Certificate, whilst confining your flying to the limits of the Licence or the Medical, whichever was the more restrictive.
Unfortunately, EASA forgot to include the privileges of a LAPL in those of a PPL, although they did remember to include them in the privileges of the CPL and an ATPL.
This means that, if you have a PPL and you want to use a LAPL Medical, or the LAPL period of a Class 1 or Class 2 Medical, you have to physically 'swap' your PPL for a LAPL!
To do this, Fill in the online application form here:
https://apply.caa.co.uk/CAAPortal/te...m?formCode=PVI
with a payment of £151, and
post your PPL back to the CAA. (You cannot 'hold' more than one EASA Licence in the same Category at the same time, so they
must have the PPL back, before they can issue the LAPL!)
Note that you cannot fly as PIC in the period between sending your PPL back, and receiving your LAPL. (Approx 6-8 weeks at the moment!)
Wish you never asked?
