Hi,
The conversion tables for going from a nat'l licence to a JAR-FCL one are dependent upon, amongst other things, your hours, MP/SP a/c, etc.
You will find all details in JAR-FCL 1 (Aircraft), or 2(Helicopter), in Appendix 1 to JAR-FCL 1.005 resp. 2.005.
Recognized countries as of today are Iceland, UK, Denmark, Sweden, Finland, Spain, Belgium, France, Netherlands & Switzerland. (Not all have implemented Helicopters yet).
Btw, EU status has little to do with this, JAA extends beyond EU.
Hope this gives some answers!
