No mention of reducing Rotor RPM ? I know the initial reduction will aggravate the left yaw, but the resulting INCREASED induced drag/ torque and DECREASED tail-rotor effectiveness would definitely be two resources I’d want to use in that situation.

Just a thought here.. but I was wondering how about slowing down and climbing simultaneously to keep power required high and then basically taking your sweet time descending in an OGE hover or very slow forward flight so that power required is high (naturally being very cautious not to get into VRS). What do you guys think?

Does anybody remember the Enstrom caught by a news chopper doing a stuck pedal landing? He was yawed left on approach, and I thought he'd pull a little power to align with his ground track and then run it on, but he ended up going another 180 degrees or so at the termination of the approach and landing sideways. Any explanation? The video is here: is here.

I agree that in general there’s less work to be done on the pedals (anti-torque) at a high airspeed due to the vertical stabilizer. However, if you think about the number of times you notice the trim-strings aren’t vertical (or for those with a turn-coordinator we “step on the ball”) you’ll notice that in any crosswind we do have to crab. When we crab we’re using our anti-torque mechanism (I’m purposely not saying tail-rotor just to include all those NOTAR guys

So at max cruise we still need to maintain our heading while keeping the aircraft positioned with its nose to the wind. Now in zero-wind conditions or in “wind from 12 or 6 O’clock” conditions there’s no doubt the vertical stabilizer is doing its job — keeping us on course.

R Kirk,
I believe as you.,, @ max cruise the tail rotor is doing very little work,as the vertical stabilizer is working at a high
efficiency to counter the yaw. It is only when you begin to reduce power that you need right pedal to maintain heading.
To reiterate,,Only when you change power settings @ cruise speed do you need to adjust the pedals
Of course this is my opinion ,,,,I could be wrong..ha.

Am I misreading the last sentence in the 2nd paragraph? At max cruise, would not the tail rotor be producing very little thrust?

Avi, I’m looking forward to learning from your experiment as well… if you can get a video of it that would be awesome!

Tim;

Though I may have read it wrong, sounds like you are describing a “quick stop” method, which I hadn’t really heard or tried before. I will go out and simulate and see how it works…
