Short YouTube transcript where Kenny Keller explains the ‘sprag clutch check’ and emphasizes adding right pedal during throttle roll-off to prevent the helicopter from spinning on slick surfaces (snow, ice, wet pavement). He recounts an anecdote about an instructor (Hauser) who rolled off abruptly without right pedal and nearly caused the tail boom to strike gas pumps.
Sprag clutch check.
Yeah, sprag clutch check. A lot of people have come here from wherever. I'm surprised at how many rated pilots working on vast ratings. They've come from the south. They have. They've never heard about adding right pedal when you roll off, throttle splitting your needles. And it's simply so that the helicopter doesn't spin when you're on a slick surface, snow, ice or even wet pavement. And people go, what? I never heard that before. Yeah, up here in the northern states, anyway, when we roll throttle off, just put the needles, we add right pedal. And we have video of Hauser doing some teaching in Enstrom and they rolled off too abruptly, didn't have the right pedal when he was teaching somebody and the tail boom came around, almost hit the gas pumps.
Yeah, that's why as soon as you start talking about. That's why I thought about Hauser talking about his video.
