The Controller asked:
"errr, why is pushing the right pedal "wrong" and why does it make the collective pop up???"
All to do with the mixing box for the 76. A triumph of science and technology over common sense. Under most conditions, it does a great job of putting in compensatory inputs to cover the secondary effects of controls. But sometimes, you get an input you don't want - pushing the lever full down gives a pedal input, or conversely, a pedal input can move the lever. In tail problems, it is sometimes best to put your feet on the floor, to avoid giving yourself a scare when the collective moves uncommanded.
Simulators are a great teaching tool. Where else can you set your engine on fire and use the extinguishers to try to put it out? Or get a Txmsn Chip light, all the bad noises, oil pressure lights and such, and choose to ditch it in the Old Pacific Sea? Or have an engine fail just as you move off the edge of the Wall St Heliport, pop the floats, and plop into the river? It even bobs along on the water and makes bubbling noises.
What it is NOT useful for is the sim instructor showing how he can fly away from a tail fail in the hover - according to Saint Nick, the sim was never designed or expected to be flown in that area.
