Helicopter superstitions and "old wives" tales?
Stu
I've done the same thing if the tailrotor drive shaft was slick. The last TomCat I flew had some kind of compound they called "Bear Grease" slathered on the drive shaft as a corrosion preventive. It has a lack of "slick" to it and did not lend itself well to slowing the rpms with your hands! In fact, the stuff has the same consistency as the Rhino coatings in truck beds... |

While many focus on the blades for freq problems, the damned engine is turning faster than any other components and can create confusing vibrations for the unwary. Of course if you are flying a turbine, we have a different set of conditions to deal with. I daresay, helicopters pilots have the most finely tuned sense of vibrations of most trades, except perhaps musicians? And its amazing to me how many pilots are musicians! Cheers |

Helicopter superstitions and "old wives" tales?
OK Bob you got me on one. Whats with never grabbing the tail rotor shaft to slow down the main rotor on shut down? I don't have a rotor brake and have used the hands on (no gloves) approach to speed up the slow down on the MR. Me too. That's how I stop the mains when I fly the C300... Learned from my CFII when i asked "Does this thing have a rotor brake?" He said, "Follow me." then hopped out and grabbed the shaft.. "This is it right here.." So,,,,, throwing a wet towel at the TR hub, is not a good idea then? g Cam. |

In the aircraft I've flown you sometimes can feel it in the pedals and you may feel like your feet are going to sleep. Other times you may feel it in the door frame when you touch it with your hand. I don't know what an R22 feels like though. Never had the urge to scratch my nose while flying. Must have good tailrotors on the ships I fly. Now I have had the urge to scratch my "boys" while flying - I wonder what that might indicate. My nose itches like an SOB when I'm flying. Rarely on the ground at flight idle, but with skids up...all the time, though somewhat less at straight and level than at max power. I thought it was just nerves. It only happens in the R-22. |

....."particularly since most are half deaf" Musicians or pilots? I suppose the rockers are both? I know my high freq hearing has deterioratred over the years of flying piston and turbine equipment but I'm still able to tune my cello. bass, and guitars OK. I have a hard time hearing my wife sometimes though......ggg |

In which case the machine has a problem - Get a Vibration analysis done before something fails! Slatts |

That's wierd.. I've never experienced an itchy nose in the R22.. My ass goes numb on long (2+ hours) flights but I think that's more the thin seat cushion than anything else. I've never had anything go numb in an R-22, but my nose itches in all of them that I've flown: Standard, Beta and Beta II. Standing 6'1", though, I do have trouble stretching to my full height after 2hrs+ in right seat. Even so, a bad day in R-22 is better than a good day doing most anything else. |
