SF Heliguy,
Definitely worth reading Spiral Tap's list - that's almost verbatim what I go through with pax. It may seem obvious but it's also worth adding that they should keep their heels (especially high ones!) clear of the pedal attachment points and stay ESPECIALLY clear of that uppy-downy lever to their right. I explain that if they push down on it, then a big hand from above does it to us, too. It seems to work...
The final thing for first-time pax in a heli, especially the R22, is to mention how twitch it can be in the hover (especially for low-timers like you & I) and that it will
smooth out in the cruise.
