Camp Freddie,
I may be mixing this up - my understanding was that if you have enough relevant experience, AND the TRTO has the exemption to the 5 hour min from the CAA, then you MAY be allowed to do 3 hours conversion training instead of 5. I can't point to something in LASORS that supports this, mainly because (like you) I simply don't have the time right now to trawl through it
You're doing a multi-crew co-op for R22? What requires multi-crew in an R22, apart from training (which isn't really multi-crew)?
