PED barrel roll in 172
I competition or air combat, I'd agree. But if an airplane
can roll to 60 degree bank it can be held in the roll and it will become inverted and then because of the inertia continue back to upright. If you stop inverted you will have problems because most engines will quit after a short while, you might have some reduced aileron control and you probably didn't hold forward elevator so you split S'd out and roll control was returned. You just could not do a competition grade hesitation roll. If a Pitts S-2 starts a snap roll and the prop breaks off the hub, does that mean a Pitts S-2 can't do a snap roll? And if a Cessna 172 does a barrel roll, does that mean that all Cessna 172 PILOTS are capable of doing barrel rolls? -- James H.

That's good, but I've heard of one case where the ailerons
moved together up and down, not differentially. Direct lift control, but is right up or down? I don't that airplane actual tried to take-off. If you box the control you can check for full and unrestricted travel for elevator and ailerons as well as correct rigging. I have seen wire bundles get loose and block control travel and you might see the ailerons move correctly, but you might not have full travel of the elevator. This is a killer, take off with engine failure, you can have a good chance to land without any damage. Have the controls locked, blocked or reversed and you're a passenger in a missile. The WSU football team DC3 tried to take-off with the gust locks installed on the tail, a C310 in Tulsa back in the early 70s took off with the controls reversed and immediately rolled into a smoking fireball. These are pilot error. The mechanic made a mistake, but the pilot has to check and verify... FREE and CORRECT. Test flying is any first flight after any work is done to the airplane, from a tire or oil change to a control replacement. -- James H.

But if an airplane
can roll to 60 degree bank it can be held in the roll and it will become inverted and then because of the inertia continue back to upright. By the time that happens, the nose may well be pointing down. You'd need to push, and you might not have enough elevator authority to keep the nose on the horizon. I don't know; I never did it in a 172. I can certainly imagine other planes that don't have enough authority to keep it going. If a Pitts S-2 starts a snap roll and the prop breaks off the hub, does that mean a Pitts S-2 can't do a snap roll? If it comes off every time, yes. -- The monkey turns the crank and thinks he's making the music. for Email, make the obvious change in the address. |

Also, interleaved quoting (AND trimming quotes) is called netiquette - the manners of Usenet. Transplanted to real life, "I think Bill Gates like top posting, why should I change to satisfy you?" could become: "I think the airlines like straight in approaches. Why should I enter the pattern on a 45 to downwind just to satisfy you?" "It's too much effort to wait three seconds to hold the door open for the person following. Why should I wait three seconds just to satisfy them?" "Why should I say please and thank you? Some _insert rich person here_ gets by quite OK being extremely rude, so why should I change to satisfy you?" "Why should I move over to the right lane? Why should I leave my comfortable rolling roadblock position just to satisfy you?" Additionally, top posting costs people money. Top posters usually don't trim their quoted material which can get quite long after a while.

Additionally, top posting costs people money. Top posters usually don't
trim their quoted material which can get quite long after a while. Those reading Usenet when they are passing time in the airport, using their cell phone, have to pay per kilobyte. That's one place where I disagree - top posting saves money. Although there may be a correlation between top posters and post trimming, it is the post non-trimming that costs money (to others), not the top posting. Actually, top posting saves money for those who, after reading your comments, don't need to read what you were referring to (because they remember it), and therefore don't need to download it KB by KB. It's available however for those who need a reminder. For a bottom posted message, one must download (often repeatededly) a message one has already read (or at least parts of it) before getting to =any= new stuff; that is wasteful of costly KB. Sometimes top posting is good, sometimes bottom posting is good. Usually interleaving is best. But there are never any absolutes.
