Mr Carr,
1) If you mean that every time an examiner signs a licence for the revalidation of a rating, or the renewal of a rating that has expired for not more than 3 years and/or has not been moved to the rear of the license, the answer is no, you will not be getting a reprinted licence on those occasions.
there is only limited spaces on the certificate of revalidation, so are we supposed to ask for a new licence every so often or will they be sending out a new one every year? or other fixed period?
