barrel roll in 172
Geez, Morgans, can't someone ask a simple question about whether an
aircraft can perform a roll without you jumping to the absurd conclusion that he's going to run right out and do it? There is such a thing as "idle curiosity." Take your meds and calm down. AJ Morgans wrote: "john smith" wrote Certified? No. Possible? Yes, but you will finish much lower than where you started. Don't encourage that type of behavior with a yes. If he had to ask, he is probably not a competent aerobatic pilot, and a blown barrel roll could stall the plane, or overstress it, so it fails then, or later. I'll bet he is not going to wear a parachute, either, which is required. The answer to rolling a normal category plane should be no, always. We don't want his, or someone else's blood on our hands. -- Jim in NC |

Then why a C172 with 4 seats. Fools always carry a witness.

"Andrey Serbinenko" wrote in message ... Possible? Yes, but you will finish much lower than where you started. So, basically it's just because of a low-hp engine that the maneuver can't be properly executed? Andrey Horsepower has absolutely nothing to do with the ability of an aircraft to do a barrel roll. Airspeed and energy are all that's required and this can be supplied even in an aircraft having no engine at all such as a glider or a sail plane. It helps of course if you have horsepower, but horsepower simply allows for an entry into the roll from a higher nose attitude. Also, barrel rolls can be done using various amounts of positive g as long as positive g is applied to the aircraft through the roll. The problem in discussing this issue in the context of using a normal category airplane to do it, even considering the utility envelope if available on such an airplane, isn't whether or not the maneuver can be done. It's whether the pilot in such an airplane can keep the execution of the roll inside safe parameters. I have done barrel rolls in demonstration many times, as have pilots like Bob Hoover, Bobby Bishop, and many others; not to mention Scotty McCray using a sail plane. The issue as I've said isn't whether or not it can be done in non aerobatic certificated airplanes. It most certainly can be done. The issue is that to do ANY aerobatic maneuver SAFELY in these airplanes, the maneuver has to be perfectly. There is little room for mistake or error. It is extremely easy due to the lack of aerobatic performance; ie roll rate and indeed "horsepower" to get these airplanes into extremely dangerous recovery situations if a maneuver is botched. This is the reason why you will get the type of answers you have been getting on this newsgroup. No one here knows who you are or why you are asking this question, so quite naturally, the overwhelming reaction of the group at large is to post an answer to you that not only protects you, but as well sets others who might happen upon what has been said here, straight on this issue.

Why didn't you ask that in the original question then?

Yes I know what FARs say, and what POH says, and no, I'm not going to read this newsgroup and go break my neck the next morning. What I was hoping to hear was an opinion of someone who's familiar with what is involved in test-flying for normal/utility category and how much it covers the type of stress imposed on the airframe and systems in a barrel roll.

The reaction is probably due to a freshly minted private pilot who recently posted a link to a video of him and his instructor doing a roll (or was it a loop?) in a C-150. Publishing such blatant disregard for regulations in a worldwide public forum casts a bad light on all airmen, and is guaranteed to receive the wrath of the readership of this newsgroup. |

That road is the one in front of the bobbit's arpartment complex. It was quite busy for a couple of days afterwards, people wanting to see the complex and the area where the she dumped the "evidence" Long before Lorena did this, it is well known that Thai wives do this to their cheating hubbys with scissors and feed the "evidence to the ducks leaving no chance for reattachment. g Monk |

But I agree that an instructor taking a video most probably doesn't qualify as an assistant. You haven't been reading this newsgroup very long. I read it occasionally. And even if I do, I don't save everything to my brain. Stefan |

Asking about such a procedure, IMHO shows a possible lack of judgment Asking a question never shows any lack of judgement. Doing something without asking may. developing. Any reasonable,sane person would know that a barrel roll in a stock 172 is a very bad idea, He didn't ask whether it's a good idea, but whether it's possible. The first safety rule of aviation I've learnt was "never assume". Reading this group, it seems that many pilots are assuming an awful lot. Stefan |
