Could the stick position be used as a Angle of Attack indicator? True or False: The stick determines elevator position and elevator position determines angle of attack. When the critical angle of attack is exceeded, the wing stalls. So, given a design with enough elevator authority, if the stick is in your lap, then the wing is stalled. If the stick is, say an inch farther forward, the wing will not be stalled. Let's stipulate no flaps/slats, calm air, normal CG, positive G, and plenty of elevator authority. Maybe use a plane such as the Luscombe 8A for the sake of this discussion. That will keep things straightforward.

I guess the crux of what I'm asking is: why couldn't the stick be used as an angle of attack indicator? Let's assume a pilot is able to very precisely detect the stick position, or that maybe an indicator is installed in the panel which is connected to the bottom of the stick under the cabin floor.
For a given set of configuration parameters, CG, weight, power, G loading, you could theoretically use stick position as an approaching stall indication.  Problem is, the actual location would vary with all those parameters, so if you had a stall indicator device that was measuring and displaying stick position, you would constantly have to vary the calibration with power setting, flap position, G load, all up weight, and center of gravity.

So, take the apparatus you would have developed to go under the floor to measure where the stick is at, and move it out to the wing with a vane that gets blown on in the clean air flow, have THAT drive your indicator, and voila!  No need to adjust for any configuration variables and you know exactly where you stand relative to stall at all times and in all flight regimes.
