wrote: As another reference point (and a crude way of measuring the negative Gs), I routinely read about guys doing the "up-down" maneuver to the point where their engine sputters due to fuel starvation. I've done that with Cherokees since the 1960s. It doesn't hurt them at all. And it is a wonderful way to teach the kids about physics. It's called a parabolic arc and it's not an aerobatic maneuver. Since that flight I've carefully inspected the empennage, and there is obviously no visible stress or strain, or I wouldn't be flying it -- but how can you really know without extensive metallurgic testing? Think about it Jay. When you're just flying along, there is a large load on the the stabilator forcing the tail down to make the plane stable (hence the term). When you "unload" the stabilator you've given it a nice little rest. I knew a pilot with a Commanche that put 50 pounds of lead in the tail cone. It made it go faster. Really not that much faster, but the plane flew better. That was also a long time ago! And I loved flying that Commanche. If you've ever looked at the stabilator attachment on a Cherokee you will marvel at the simplicity and apparent fragility of the design, so inducing excessive negative-G is something we never, ever do. Don't ever look closely at a helicopter. Mike Weller |

Did you mean to say intentionally?

Mike MU-2 "Jay Honeck" wrote in message news_JKe.239722$x96.59507@attbi_s72... During primary training, many moons ago, I was growing frustrated with the sedate nature of our flying, so I asked my flight instructor (Bob -- a guy with 20K hours in every known flying machine) when we were going to get to the "fun stuff"? He didn't know what I was talking about, so I told him I wanted to see what these things could actually *do*... At which point he smiled that crooked smile of his, and proceeded to do a wing-over with a recovery out the bottom, going the opposite direction! I was whooping and hollering for more, but he just went back to our lesson for the day.... Nowadays, Mary and I are very cautious in our Pathfinder, rarely exceeding 45 degree banks, and never pulling more than mild G turns. Mary hates steep banks (except in a Super Decathlon -- then all bets are off!), and the most rambunctious thing we ever do are "Up-Downs" (as the kids call them), which is a firm pull up with a steady push-over at the top that induces negative Gs in the back seat. Just curious -- what do you guys do with your spam cans? I've seen video from inside a Cessna that shows a guy doing some pretty radical maneuvers, but in real life what's the most you push your aircraft? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

And for you die-hard Cessna fans, don't EVER look at the wing spar attach points... You'll never do a steep turn in your 172/182 again! ;-) -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |
