Rolling a 172 - or not
If I'm crusing along at 100 KIAS in a 172 in clear air and I roll left
while maintaining neutral rudder, what will happen if I don't neutralize the ailerons? I'm picturing the plane rolling on to its back while losing altitude and either completing the roll (doubtful) or stalling into a dive and recovering in the other direction , right side up. (BTW, that's a split-S, isn't it?) I wouldn't anticipate a spin unless some serious rudder was cranked in the direction of the roll. -Scott "I feel like REALLY flying today" Lowrey |

If the elevator is kept neutral, your nose will drop throughout the roll -
no stall. You'll probably be over redline by the finish. What actually happens as many acro students will attest to (and many dum dum wanna bes who scare the living bejezus out of themselves) is that upon approaching inverted and while noting the sudden nose drop, ones natural response is to pullllllll. That's an inadvertant split S. Very easy and natural to do. Almost unavoidable for the untrained. Good way to take the wings off. That's why instruction is so valuable. Learning to start nose up and push a bit when you otherwise will want to pull will result in a passable roll of sorts. A little acro skill may give you what you need to push and roll if you ever find yourself upside down due to wake turb or something. It's stupid to do in a 172 though. Same for a snap. My Maule will never see one while I'm in the seat. And a hex on CFIs that like to flip it to 'impress' their impressionable students. "Scott Lowrey" wrote in message om...

It's not going to spin unless it's cross controlled, and stalled. Nose
low and excess speed is likely to be the result. Vne and overspeed of the engine and both bad things. It's like to see that on flight sim. Wayne I wouldn't anticipate a spin unless some serious rudder was cranked in the direction of the roll. -Scott "I feel like REALLY flying today" Lowrey |

Crosscontrolling is not necessary to instigate a spin (as a matter of fact many will argue it is less likely). |

Dont forget that the fuel is gravity fed to the engine. Stay upside down
too long and your gonna lose power..... Tim "Scott Lowrey" wrote in message om...

Not if you maintain positive G all the way around (as in aileron roll). Of course, a 172 handles about like a truck! It would ba similar to having sex with Roseanne Barr!

You don't have positive G all the way around in an aileron roll. To maintain positive G, you need a barrel roll. vince norris |
