I agree that to be able to teach for something, the Instructor must also hold the same (or equivalent) qualification.
The wording of
FCL.910.FI FI — Restricted privileges
(2) in all integrated courses at PPL level, in case of aeroplanes and helicopters;
threw me a little.
Is the reason for this paragraph that, even though they would have over 200 instructional hours, some CPL Instructors might still be Restricted?
