The CAA have previously confirmed that ANO Article 168 renders a UK-issued Flight Instructor certificate with FCL.945 privileges eligible to sign for revalidation of class ratings in national licences for those ratings which they can instruct. Therefore a FI with FCL.945 privileges can sign for class rating revalidation of a microlight class rating where they have conducted the associated training flight and the revalidation requirements are met.
R Examiner authorisations are still issued by the UK CAA and are applicable to national licences. Use of this might be required for cases where instructors have not flown with the pilot or a training flight is not required (5/13). R Examiners hold the appropriate authorisation to sign for revalidation by experience of class ratings in national licences where authorisations typically specify which class ratings the individual can sign for.
