Amazing Technology Now Being Fielded Worldwide (Part II) The point of the centrifuge is to increase the realism of flight simulation. Or, as ETC puts it, to "continuous motion cueing and sustained G cueing in real time flight." There has been a great deal of to-controversy in the training and human factors worlds over the last few years on the value of motion cueing. Some studies indicate that it has little value. The difference may be one of degree: traditional simulators can provide motion cueing that hints at what the airplane can do, but they can't sustain acceleration (G), they can't do negative G, they can't reverse from positive to negative - all things an actual airplane can do. Even the momentary, transient accelerations felt in an ordinary full-motion simulator are stric
