But, it may be a
good idea for you to look up the definition of "scalar". It *can not*
include a directional component. Conversely, AOA can not exist
without one.

Angle of attack does not "include a directional component". It is
just an angle, which is a scalar quantity.

If what you think is true, then it is possible to determine the AOA when
the aircraft is parked. Do so, and I'll revise my thinking. The wonderful
thing about this level of mathematics is that it is not ambiguous. If any
usage results in a violation of the definition, then the usage is wrong,
period.

I don't give a flip whether you revise your thinking or not. Your loss.

Not really.

Have a nice weekend, and fly safely.

Sorry if I was harsh. The point is, usually one coming seeking knowledge is not
quite so sure of himself. You might do better to ask questions rather than
asserting that you know everything, that you are right, and anyone claiming
otherwise is "wrong, period". If you rely on a brief dictionary definition of
terms, it is likely you are missing a lot of nuance and detail.

Anyway, a high-school or undergraduate mathematics text is a better source of
knowledge about scalar and vector mathematics than either a dictionary or this
group. I recommend you get one and read and understand it.

--really-- gone from this thread this time.

Your guidance is appreciated, Dave. However, I think you may have an
impression of me and "how we got here" that doesn't reflect my
"self-assurance". I am not claiming to "know everything", or even nearly
so. I do ask questions, such as the one that I've repeatedly asked, above,
and so far have gotten only replies that I'm wrong and everyone else has
the "right answer period". As well, a lot of my "attitude problem" stems
from the claims that were erroneously attributed to me, and the subsequent
responses from those that thought those attributions were true, or at
least didn't acknowledge that they weren't.

Frankly, I think we've all been dancing around this, and I suspect it's
gone way beyond its importance with regard to how we use AOA in every-day
aviation. ;-)

(chuckle) Unfortunately, I got rid of those many decades ago. However, the
few calculus, geometry, and logic texts that I still have from my time in
engineering school (also many decades ago, so I'm not claiming any special
priveledge on the basis of that experience) so far don't refute what I've
presented: a vector with a magnitude of zero is legit; a scalar with a
directional component is not.

I can envision an argument that hasn't been presented that would establish
AOA as a scalar, and it relates to the question the AOA of an aircraft
while parked. I'm searching for a valid example of it (off-line, btw),
but, so far, I've come up dry. If I do find one that supports the argument
I envision, I'll present it as a follow-up refuting my own assertion,
along with an apology to those I suggested were "wrong". Not that they're
holding their breath, since they just think I'm just "wrong", anyway!
