I've heard that we can do the BFR and IPC, for an FAA CPL-IR single and multi engine, in a single engine aircraft, and still have the multi rating. Is it true?
I think we're getting confused here.
If you hold a FAA CPL SE & ME IR, yes you can do the BFR and the IPC in a single engine aircraft.
The BFR and IPC are not category and class limited.
It's only in JAA-land that a MEP expires.
