It's not been that accessible for pilots of light single helis though - I think that is his point, 'amateur' owners looking to push on in poor weather using synthetic vision.
Synthetic vision is available to every Foreflight and Garmin Pilot user on the ever ubiquitous cockpit iPad, which describes nearly every light single pilot I know.
That said, I've never seen anyone fly based on synthetic vision. I personally find it terribly distracting. For me it is much easier to think in terms of the basic instrument readings. I wonder that if that is because synthetic vision contains no 3D cues.
