Has anyone seen wheelbarrowing occur? Prima facie, it appears too I've seen it a couple of times, but porpoising is much more common. Wheelbarrowing is due to forcing the plane down when it's still going too fast to land. Porpoising OTOH is from not getting the nose up soon enough. The plane is rotating (nose coming up) when the nose wheel hits first, this leads to the nose rebounding up and the mains come down and rebound. You can get some pretty dramatic bounces this way. The best way to stop a porpoise is to just give it the power and go around. The typical porpoise ends up with the pilot behind the airplane (OK so it started that way), and each bounce gets bigger. They say three times and out. I saw two instances where this was true. On the third time they busted the nose gear right off on both planes. improbable (ludicrous almost) a thing to happen but even the FAA Airplane Flying Handbook copy that I have mentions it! Some well known planes are quite prone to porpoising if the pilot gets behind it. They are a bit heavy up front although the CG is fine. The problem comes in landing. That is why you see cautions about checking firewalls for wrinkles when purchasing a used plane. Also, while the ways of performing a flare is mentioned at many places, the reason for a flare is conspicuously absent everywhere. Just why is Actually it's not. *Almost* anything that flys flares on landing whether it has jet engines or feathers. a flare needed vis-a-vis a 3-point landing? After all, birds just come in and sit, without having to flare... Virtually all the birds I've seen flare and they are really good at it with many almost coming to a stop just before their feet touch down. As some one else mentioned, with your interest you should take up flying if you haven't already.

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? Prima facie, it appears too improbable (ludicrous almost) a thing to happen but even the FAA Airplane Flying Handbook copy that I have mentions it! I've seen it at least twice. The worst case was a Cessna trying to get in before the field closed for the Sussex County Airshow. The nosewheel hit first and bounced. Then the mains hit and bounced. The nosewheel came down again, harder. The plane started porpoising. The third time the nosewheel hit, the tire was nearly flattened. The noise was impressive. He managed to keep it down on the fourth strike -- I think the plane had just given up trying to fly by that time. Also, while the ways of performing a flare is mentioned at many places, the reason for a flare is conspicuously absent everywhere. Just why is a flare needed vis-a-vis a 3-point landing? Typically, the nosegear is more delicate than the mains. The steering mechanism also may give trouble at high speeds (shimmy is a problem with many designs). The general idea is to keep the nosewheel off the ground until you're sure there won't be a problem. It's also true that the consequences of "wheelbarrowing" can be severe. If the nosewheel touches before the mains, the back end of the plane continues down until the mains hit. Once the mains hit, the back end stops traveling down, but the plane continues to rotate, and the nose wheel leaves the ground again. Over-reaction by the pilot may cause the nosewheel to come back down even harder. There have been cases of prop strikes, flattened tires, loss of directional control, and even cases in which the nosegear broke off. And doing it in front a a thousand people or so is embarrassing. Flaring properly is an excellent way of ensuring that this never happens to you. George Patterson The desire for safety stands against every great and noble enterprise. |

From general observation, I totally agree. The guy today was carrying significant power all the way to the runway and must've touched down at around 100 - half way down the 3500 foot strip. I could see him where I stood, and he looked busier than anything I can make an analogy for. I kind of felt bad for him.

God forbid they need to do something they'll learn from! z |

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/ |

I guess I'm just more creative. I was getting a check-out in a 207 long ago. There was just the CFI and me in the airplane, not a lot of gas. The first takeoff we used 10 or 20 flap, I guess I held a little forward pressure on the yoke because I was worried about this "big, heavy, fast airplane" coming off the ground to slow. G The initial liftoff was main wheels first. I can tell you from experience that a 207 doesn't handle well with just the nosewheel on the ground. Since I wasn't doing very well driving it I rotated to try flying it and things calmed down. I have NEVER done that again. -- Dale L.

I've seen it a couple of times, but porpoising is much more common.
We had a friend earn his ticket in Iowa City a few years ago who porpoised a rental Archer so badly that the nosewheel collapsed and the engine had to be torn down. The prop was a total loss, too, of course. Sadly, it rattled him so badly that he absolutely disappeared off the face of the earth after that episode. I've never seen him again, and I presume he's quit flying. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |
