O.T. Euphemism runs amok.

OK, Robatoy, tell us of case in which an aircraft at a given angle of attack stalls at one airspeed but not at another.

What is becoming clear is that you do not know the difference between angle of attack and flight path angle.

[Robatoy]

ack stalls at one airspeed but not at another.

le of attack and flight path angle.

You wrote:

"Stall warning works by angle of attack, not by airspeed. Angle of attack was never unusual."

NO mention of flight path angle. I do understand that you are now trying to introduce other variables in order to try to regain some lost ground from your erroneous previous statement. That's your style and that's okay, but what's next? A denial that stall specs change with altitude?

In real time, we'd probably enjoy a few pints and get along just fine, but in here you have to stop treating people like they're stupid.

[CW]

What is very clear to me J is that you changed something to avoid my (and probably many other's) bozo bin.

[Lobby Dosser]

Heard and Saw one of those on a landing at LA from Santa Barbara. Little prop commuter with curtains for the door to the flight deck. We must have hit the wash from a big jet. Was real sphincter control watching the pilots wrestle us onto the ground in one piece. Some superb flying ...

[J. Clarke]

"NO mention of flight path angle."

What of it? You are the one who went off on a tangent about F-16s climbing= vertically and when called on it you got pissy.

"I do understand that you are now trying to introduce other variables in order to try to regain some lost ground from your erroneous previous statement."

What "erroneous previous statement" would that be? And if you believe it t= o be erroneous then please provide a counterexample.

"That's your style and that's okay, but what's next? A denial that stall specs change with altitude?"

The angle of attack at which stall occurs does not change with altitude. H= owever the airspeed at which an aircraft in level flight will achieve that = angle of attack does change with altitude. If by "stall specs" you mean th= e stall speed you are correct that it changes with altitude, but stall spee= d is calculated from angle of attack and then verified by test.

Find a copy of "Theory of Wing Sections" and read through it and you'll end= up with a much, much better understanding of stall. If you don't have an = engineering or physics background though it's going to be a tough slog.

"In real time, we'd probably enjoy a few pints and get along just fine, but in here you have to stop treating people like they're stupid."

Unlikely in the extreme--I'd have to leave early while I was still sober en= ough to resist the urge to throttle you.

[Robatoy]

enough to resist the urge to throttle you.

Pretty much what I expected as your bitterness towards many in here shows in almost all of your posts. That bitterness will chew you up inside-out. Sad, really. Sad to the core. (Boy, you really don't like it when somebody points out your mistakes, eh?)

Oh.. and an attempt at throttling me would be a task which would result in an unexpected reaction .. to the extreme.

[Robatoy]

Oh, and don't e-mail me behind the curtain... only my friends are welcome to do that. You're pathetic.

All of the other negative points and barbs between you aside, he is correct about the angle of attack determining the point at which a wing stalls.

Airspeed, attitude, altitude, load factor and other items all muddy the picture and are related, but fact is that an angle of attack indicator is what will tell you when the wing is going to or has already stall.

That is one reason all modern airliners and heavy transports have a couple of them on the side of their fuselages.

[Robatoy]

...and this is different from what I said..how?

[Robatoy]

And I never disputed that. What made me respond, is Clark's faux-authorative arrogant assertiveness when he tosses out a statement which in itself is incomplete. He sure-as-hell would be all over somebody else were they to make an incomplete statement like that. ...besides, I like jerking the asshole's chain.

[Markem]

When I was flying the best stall indicator was my ass in the seat, it went off before the audible stall indicator ever did. That is why you practice at altitude.

It takes a while, but worth the effort.

[J. Clarke]

Yep, in many aircraft under many circumstances you can feel it coming. However when there's half a kiloton of ammunition in the back and you're coming into a short field with zero-zero visibility you want all the help you can get.

[Robatoy]

:-)

[J. Clarke]

So let's see, you don't respond to one single technical point, just bluster. Why would that be?

[Robatoy]

er. =A0Why would that be?

You mean that red herring you dangled out there?

Will stall speed vary with the type of finish painted on the wing surface?

[Lobby Dosser]

------------------------------------------------------------------------------

Question should be will it measurably vary with the type of finish. Answer is probably yes. Paint has mass and mass affects stall speed.

[Robatoy]

How about the texture of the paint?
