In the absence of a simulator for older types still in use, do they use a vertically displaced threshold (C.5000' ?) for the riskier approach/go around procedures?. An appropriately configured GPS box would provide ILS info to the 'threshold'. Only missing reference (at night) would be the app. lights when 'breaking cloud' at 200' + 5000.
I'm sure you'll tell me if I'm talking out of my Civvy hat.
