An ATPL and a CPL contain LAPL privileges which can be exercised provided at least an LAPL medical is held.
This is incorrect, since a CPL or ATPL holder does not hold a LAPL.
If you hold an ATPL, and look in Section II of your licence, your ATPL will show the piece of paper is an ATPL, CPL, and PPL. In order to exercise the privileges of any licence, the appropriate medical is required.
Part-MED (MED.A.030) requires the ATPL and CPL to be validated with a EASA Class One medical, and the PPL to be validated with at least a EASA Class Two medical.
So, whilst you may be able to exercise LAPL privileges with an ATPL in accordance with FCL.505, you may only validate that ATPL licence with a EASA Class One medical.
