Glassin, Gypsy,
Appologies for any confusion caused. I didn't know if it was single pilot. Basically, yes you are right. If it is single pilot rated then no problemo - but obviously the right seat guy can't log their time. With regard to JAR PPLs, only IR rated pilots may take the right seat in a multi-crew ship regardless of commercial or private ops.
Great offer though. Wish I could take it up!
