I did a sim. session some years ago where the instructor failed all the goodies, leaving us with what amounted to a 300 tonne Cessna 150. No speed tape, no flight director, no envelope protection, just basic flight instruments.
In most sim. sessions, I usually leave it to the FO to fly the aircraft while I deal with the non normal procedures. In this case, that proved to be impractical, for within minutes, we were in an extreme unusual attitude - the FO just could not cope with hand flying without the goodies. I had to fly the sim. myself and let the FO handle the non normal checklist.
...and I have to admit, my own flying, without all the toys, if at least semi-controlled as I shared my IF scan with monitoring what the FO was doing with the non normals, left much to be desired and would not have merited a 'pass' in what used to be required in an instrument rating test.
