For the umpteenth time, when you need to re-validate your SEP (Land) Class Rating, you will need to have met one of the following requirements:
Either: To have flown at least 12 hours in a Single Piston (Land) aircraft in the second 12 month period, of which 6 hours must have been as P1C including at least 12 take-offs and landings as handling pilot, and of which 1 hour must have been a training flight with an instructor (who must also have signed your logbook entry for this flight).
Or: To have flown a revalidation Proficiency Check with an Examiner in the last 3 months of the Rating’s validity, for which there will probably be an Examiner’s fee. I charge £75, but some are charging £150 or so....
When you present your FCL 150CJAR for revalidation, you must also produce your personal logbook and complete a re-validation form with your details. This will then be signed by your Examiner and you then send it off to the CAA (but you don’t need to send them a cheque).
Note that the 12 hours must have been in a SEP Class aeroplane - 899 in a Boeing 737 plus 1 in a C152 won't count!
