It really is 'send three and fourpence...' I have a current R Examiner authorisation issued by CAA under the umbrella of the LAA coaching scheme, and I have an FCL.945 authorisation (as I'm sure most instructors do nowadays).
Ifitaint - thanks for your clarification. So, with the R Examiner authorisation I can revalidate a national licence even if I wasn't the instructor who the pilot flew with; is that correct? It sounds reasonable, but that has long-since stopped being a criteria...
