I have a lapsed IMC rating. I have a current lifetime CAA pre-JAR license, with class 2 JAR medical. Am I correct in that the CAA pre-JAR license will continue, (with the attached IMC if I revalidate it), in parallel with the EASA PPL I expect to get?
Yes your UK-PPL with IMC rating will continue BUT it can only be used on EASA aircraft until 8th April 2014. Thereafter you can use the UK-PPL+IMC in NON-EASA aircraft only.
So while theoretically you could use your IMC in those non-EASA aircraft most of those will be 'Permit' aircraft that are only certified for 'DAY-VFR' and cannot legally be flown IFR in IMC!
