No turboprop Rule is to avoid having to do Base training on the actual aircraft. It might change one day, who knows...
Interesting. Makes even sense, somehow...
But what are the requirements for a ZFTT? As far as I know, a candidate must have a certain experience level on a multi-pilot turbo-jet or multi-pilot turboprop with a MTOW >10t and a least 19 PAX seats in order to qualify for ZFTT.
Or does it really matter if a candidate operates a CRJ200 with a MTOW 24t or a Q400 with a MTOW 29t and more PAX seats?
