This file provides the vibrational sensory experience of an MD500 helicopter. So real you'll WANT to go through the full start up procedure as you feel the turbine engine light, the rotor spin up to idle, the accelerating vibration to full throttle, the skids dragging as you lift off or the thump of landing. It can even help you be a better sim-pilot helping you keep level in flight by "feeling" changes in climb rate, or nearing VNE overspeed, or the onset of VRS. An enhancement to your piloting skills and a vast expansion of the immersion experience.
