Aussie Standards
Type rating is=regulatory standard. ie. CASA IR issue tolerances for the type issued; End of story. An IR renewal under 217 or ATO is = regulatory standard, ie CASA issue/renewal; End of story. A companies standard can EXCEED or equal this; end of story.
This does not include or make allowances for having a good check day on one and a bad check day on another. Line checks are, by luck sometimes, very straight forward, sometimes not. Of course the sim check can always be subjective and, inevitably will raise some doubt; Particularly given the environment that check Captains have to work in....
In summary: Endorsement rating is relatively fixed to type competency,
Airline operations have subjective assessment.
Not always fair and objective but, in Australia has without doubt been backed by statistics on the safety outcome by world standards....!!!
PS. We do, however, have room for improvement. (Note: to Senator Xenophon.)
