FM that is....How do I know if our aeroplane has FM immune kit onboard? Sounds like a silly question, but when I bought in I assumed that as a reasonably priced quater share of a 4 seater single and that is was not fitted with FM immune kit. We had a group meeting recently and were discussing things and the IMC rating came up and one of he group said that all the stuff was already FM immune.....
Thinking about it there are no "VFR only" placards in the cockpit, and it would be great to be able to exercise the privileges of the IMC legally
(then all we need to do is stick it on the N reg 
) but I'd like to satisfy myself that it is indeed FM immune.....
Cheers
