OK, thanks for the clarification. Here in OZ Captains and First officers all have command ratings on an ATPL, Second officers [or junior F/Os] for augmented crews have co-pilot ratings on a CPL or ATPL.
Yep, different system, we don't have second officers, except for flight engineers. And we don't do base checks and instrument checks as such. Our training records contain all of the currency information that is listed on licenses in many other countries (i.e. base check with one date for the check, one for the signature, another for the license, whew!).
And we've gone to this warm and fuzzy AQP training system where the oral exam is often gone and the checkride is hidden in scenarios that are meant to be practical and instructive. However, since there is still the legally mandated laundry list of required items, this usually morphs into a combination of quick demos and pencil whips with little opportunity for training or proficiency. And, on many fleets, we only go once a year.
