The report states that during UA "training" in the simulator the pilots being trained were told to close their eyes while the instructor or testing officer put the aircraft into a UA. What is the purpose of that? Pilots undergoing initial instrument flying training in (say) Cessna 172 wear an IFR hood so that in theory they cannot sneak a look outside to see the horizon. In addition the instructor gets them to look down and close their eyes for the same reason - to prevent cheating.
But in a simulator where IMC is programmed, the candidate cannot cheat by looking outside. So why is it that some simulator instructors still tell pilots to close their eyes and look down while the instructor flings the simulator around and says "Handing Over, Bloggs - sort out that lot"
