Your "Frozen ATPL" actually consists of a number of different things, each of which needs to be maintained seperately:
- A CPL, which is valid for 5 years. Revalidated by sending the CAA a cheque
- An Instrument Rating, which is valid for 1 year. Revalidated by test, either on an aircraft or in a simulator
- A Multi-Engine Piston Class Rating, which is valid for 1 year. If you revalidate your IR on an aircraft, this will also revalidate your class rating
- A Multi Crew Course, which does not expire
- Credits for the ATPL written exams, which remain valid so long as you have had a valid Instrument Rating some time within the last 7 years. If you let your instrument rating lapse by more than 7 years, the exam credits expire and you have to re-sit the exams
- A medical, the duration of which depends on your age
Sorry, I do not know for certain exactly when the validity period of each of these commences, but I think it is the date the CAA processed the application.
See LASORS for more information on each of these, including renewal requirements if you happen to not revalidate before the expiry period of any one of these.
