Re: FAA IR Conversion to JAA Multi IR in UK
i should add that I see you're based in Europe, JS3. IIRC, the UK CAA is unique amongst the JAA states in allowing the 15 hour conversion course. If you have a licence from another state I believe you would have to do a full IR, no reduction would be allowed based on your non-JAA ICAO IR.
It is a happy consequence of the JAA rules for us Brits that we can do the conversion in another (approved) member state when adding the IR to our licences.
