Revalidation by Experience (SEP and TMG only)
Examiners are reminded that, for TMG and SEP revalidation by experience, any CAA or JAA
authorised examiners (aeroplane or helicopter) can sign the revalidation. That includes TREs.
If the examiner is not confident with the process then he does not have to sign.
