You will need to complete the appropriate familiarisation or differences course and record it in your logbook.

No, whether specifically requested by the applicant or if the certificate is updated at revalidation or renewal, the new SET LAND and/or SET SEA nomenclatures shall be noted on the examiner certificate if one or both ratings are reflected on the licence with privileges to instruct in them.

No, the examiner privileges appropriate to the type of certificate may continue to be exercised in the variants covered by the rating endorsement on their examiner certificate, provided that in order to act as an examiner it is necessary to be able to instruct and be qualified to act as PIC for the relevant variant.

By being annotated as a single rating, either SET LAND or SET SEA, the examiner is extending the validity period of all variants contained therein when revalidating the rating.

Whether or not the pilot may exercise them in such variants shall be verified by the person concerned by verifying that he/she complies with the requirements set out in FCL.710.
 

It should be noted that until existing licences are updated with the new SET LAND and/or SET SEA nomenclature, the revalidation certificates submitted by examinees will continue to show the original ratings.

Similarly, you may not yet have your examiner's licence and certificate updated to the new nomenclature.

It is the responsibility of the examiner to check in which variants the student or pilot is qualified and, accordingly, to conduct the test in those variants in which the examiner is an instructor; i.e. examiners may only act as an instructor in those variants for which they are an instructor.

As stated in regulation point FCL.1000(a), examiners shall exercise privileges in those variants in which they are able to instruct; taking into account familiarisation training and differences in applicable cases.

The validity date of your SET LAND and/or SET SEA examiner certificate will be the same as the one currently on your certificate.

To practice in the rest of the variants covered by the SET rating, you will need to check that you meet the requirements set out in the FCL.915 b).

No, your privileges as an instructor are limited to the variants for which you have completed the differences or familiarisation course, as appropriate, once you meet the requirements set out in FCL.915.
