I've seen porpoising. And wheelbarrowing. Very bad juju! Very dangerous.
Everyone *must* learn not to do either! The most physically dangerous thing that I see with porpoising is the possibility of stalling at the top of the second or third porpoise, after the a/c finally runs out of lift, while you are 15-20 feet off of the ground! Not good. -Frank "G.R. Patterson III" wrote in message ... Ramapriya wrote: Has anyone seen wheelbarrowing occur?

George Patterson George, is this a confession? g ducking and running Nope -- still thinking about that Cessna pilot at Sussex. I fly a Maule. There's an entire 'nother category of possibilities for embarassment. "There are two categories of tailwheel pilot: those who have groundlooped their aircraft, and those who will." Been there, done that, just once. Didn't ding self, plane or runway lights, and went up to do another two touch-n-goes to get back on the horse that threw me... The wind was gusty & getting close to my X-wind limits (nowhere near the Citabria's limits, just my personal ones at the time...), so I planned one last touch-n-go before the full stop. My approach was squirrelly, the wind gusted hard just at touchdown, and I may have tapped the brakes; the next thing I knew I was rolling down one of 09's taxiways and Tower was saying, "Juliet Tango Mike, you OK out there?" I should have gone into the grass, but Golf taxiway was at exactly the right spot for me... Got the plane looked at when I went back to the Club; no stress on it. I was another matter! We won't discuss my first arrival at Oshkosh ( at least I didn't run down the Ford tri-motor). Likewise, I missed the runway lights! Brian www.warbard.ca/avgas/ |

So far, the only time I've done it was deliberately. Landed long on a grass strip. The trees were approaching rapidly, so about 60' short of them, I locked the right brake. She spun around just as advertised. The left wingtip got within 3' of the ground. The next time I changed the tires (years later), I found blades of grass trapped between the bead to the left tire and the rim. Don't mistake that for a claim that I've kept the plane under perfect control during all my landings. :-) George Patterson The desire for safety stands against every great and noble enterprise. |

He busted the nose gear off on the third bounce. What an impression that must have made. To top it off he landed down wind. Fortunately it was a light wind. We explained to the audience he wasn't any one any of us knew. Probably from one of those big cities.

That was back in his tricycle days.
Since he became a "taildragger" pilot, he doesn't do that anymore. "G.R. Patterson III" wrote And doing it (nosewheel landings) in front a a thousand people or so is embarrassing.
