Mathematically, an "angle" by itself *is* a scalar, and I'm not arguing
otherwise. I'm saying that "Angle Of Attack" requires direction to have
meaning. Without direction, there is no AOA.

Neil, give us an example of AOA having a "direction".

Well, OK. Then, how do you determine the AOA when the aircraft is parked?

When parked with no wind, there is no relative wind and therefore NO AOA.

Stated another way, AOA doesn't exist *without* a directional component.

Directions are measured in reference to "somewhere", Up, Down,
North, South, etc. What is the reference for measuring AOA?

No. AOL doesn't exist without a =component= with a directional
component. Not the same.
