Is there a 5 year rule ( similar to the requirements for the Group A rating
LASORS E3.5
For a period exceeding 5 years from the expiry
date of the rating, a candidate will be required to
carry out dual instruction, at the CFI’s discretion,
covering the IMC rating Course with an IMC rating
instructor, and pass the Initial IMC Rating Test with
an IMC rating examiner in a suitably equipped
aircraft. If the rating has expired by more than 10
years, then successful completion of the IMC
Ground Examination will also be required.
Therefore you have until March 2012 untill this kicks in.
Group A has not existed for the past 11 years, and the old 5 and 10 year requirements died with it.
