Since an EASA licence is non-expiring, it does not require revalidation.
Come on you of all people should know the difference between revalidation's and renewals.
I am sat looking at Cliff Whitakers slide set the contains an over view of the situation. It was him that told us that as EASA only has domain over EASA CofA aircraft and that only time logged in EASA CofA aircraft was countable against the issue or revalidation of an EASA Class Rating. In order to gain an EASA Part FCL licence or add a Class rating the the time must be logged in an EASA CofA aircraft.
As I said earlier I am standing by to be educated by you as to why I am wrong.
