h88, unfortunately that's not the case.
Whilst a ATPL does indeed allow the holder to exercise the
privileges of a LAPL holder in accordance with FCL.505 (the privileges of a LAPL holder are listed at FCL.105 and FCL.105.A), the ATPL licence itself can only be validated with a Class One medical in accordance with MED.A.030 - see CAP 804, Section 4, Part N, page 4/5.
The UK CAA have also included a PPL and CPL licence for all ATPL holders (see Section II of your ATPL licence or example in
CAP 804, Section 1, Part C, Appendix 2, page 56). Therefore the PPL licence (within the same bit of paper as the ATPL) can be validated with a Class Two medical in accordance with MED.A.030.
However, an ATPL holder cannot validate their licence, or the CPL or PPL within it, with a LAPL medical.There is no equivalent clause in Part-FCL.205.A (which is b*nkers and NPA 2014-29 may fix it but in 2017 at the earliest)
One of the comments I submitted as our response to NPA 2014-29 was that the same issue has been repeated - even by incuding LAPL privileges for a PPL holder within FCL.205.A, that PPL can still only be validated with a Class One or Two medical in accordance with MED.A.030.
As I understand it, an ATPL(A) holder does not have to re-grade to LAPL(A)
If you hold a LAPL medical, then you cannot exercise the privileges of your EASA ATPL, CPL, or PPL. You can either re-grade to a LAPL or obtain a NPPL, both of which may be validated with a LAPL medical. I've compiled a handy summary of the requirements in Coaching Scheme Leaflet 3.12 which can be downloaded from here:
