If you elect to fly a proficiency check within the final 3 months of your Class Rating validity period, your Class Rating will be revalidated for 2 years from the date of expiry - otherwise it will be 2 years from the date of the proficiency check.
Being pedantic and to further my own understanding, is it not now the case thanks to EASA that the rating would be valid for 2 years from the end of the month?
Please do correct me if I have it wrong.
