Picture of FPV

82 illustrated with pictures. Or you can do first grade math applying aerodynamics 101.

Someone got it.

I think you are confused there.

Ok. What part? I have used this method on the 190 with a HUD that was very accurate and on the Bus where I could compare what I had verses the FAC (flight augmentation computer). It worked. But maybe that was luck.....if I am wrong or did not explain it well enough I am happy to admit it.

I think what he is saying, is that you are confusing terms. You cannot determine AOA in reference to body attitude at cruise, or nose up, or on the attitude on the HSI. The wing AOA is related to body attitude only in that at cruise, Boeing decides what body attitude it wants at designed cruise, speed, then sets the wing in the fuselage to attain that optimum attitude at cruise speeds.

So, AOA can be inferred, but most air carrier planes do not show AOA. I don't fly the 737, so there may be some indication I'm not aware of.

Well put, but not only not at cruise, but approach, landing or any other flight regime, including inverted. Old Mako's drawings are worth 4thousand words. Pick up a copy of Stick and Rudder by Wolfgang Langewiesche. btw, on the 76-400 there is a way to read out a snapshot of AOA, if you know where to look. It does have AOA sensor, but no display.

Fair enough. I would agree with that....

Yes, all the plane calculate or have AOA sensors for air data,performance, and flight control computers. They are capable of displaying the info if the customer buys the option, but it seems most airlines do not display it.

After all, if you had an AOA displayed, you might be able to tell what is happening if the computers turn themselves off and spout gibberish, instead of stalling the plane into the ocean from 35k feet.

Ya. That's correct. I think the technical definition is relative wind to central chord of the wing, regardless of body angle to the wind, etc.

All I remember about AOA was make sure the donut was amber and not a red or green chevron and keep it that way until touchdown on the boat.
