I spent 5 years instructing IFR in a helicopter school which had IFR B206 as well as CASA-certified IFR sims - no motion, but as realistic as you could get, with surround screens and real buttons and switches.
I allowed my IR to expire, as i intended to "retire" and just perform ground duties in the simulator, but CA$A declared I could no longer instruct in a sim. ...unle$$... I paid for a CA$$$$A per$on to come up to the $chool and check me a$ $uitable to in$truct in a $im. For a fee of cour$e. The fact that I had been using those sims for 5 years and held an instrument rating since 1972 mattered not a whit.
