SIM checks are there to tick boxes, not to check skills. Which is one of the major problems right now and has ultimately lead to the current mess.
Good point IMHO.
Over the years the training time seems to have been swallowed up by the requirement to teach/check another automatically "flown" item which has been added to the list... CAT III approaches needless to say but now we have PRNAV approaches in various forms, then of course there's the assessable LOFT exercise .... etc, etc.
With luck, with a time efficient trainer on a good day you might get time to fly a couple of circuits at the end of the detail.
