500man, other way round. Think: still valid - revalidation. Expired - renew.
Oops! My bad. Out of interest someone said to me that you don't need to pay the CAA anything for renewal (after 2 years) unless you are past the 5 year mark. Is that right?
I wish the CAA would make all of this clearer for those of us that don't like wading through the bull!!!! on their website or in LASORS.
