John Tullamarine,
Got to agree with most of that. The subject is not about type/class training - it's about "is this person up to understanding and commanding an
airliner"?
Having said that - the traditional lack of clarity around the requirements and results is disgusting. Parts of CASA do know better, but those managing this subject and the questions genuinely do not understand training or evaluation
Until those people retire (can't be far away) we're stuck with incomplete guidance (SOPs) and terrible use of unspecified methods ("the only correct answer is the one I get") rather than specific tolerances.
