Folks,

If the gliders we fly are longitudinally statically stable what you want
is a head up elevator deflection angle indicator.
That gives you the pilot commanded angle of attack.

Good observation Mike. However, three points:

Many high performance gliders have their CG set near the rear limt so they
are only mildly stable. i.e. small elevator deflection angles result in
large airspeed and AOA changes.

In transient events like gusts, AOA may not track elevator deflection angle.

In the case of winch launch, the pitch-up, and therefore AOA, may be due to
the placement of the CG hook as well as elevator control inputs.
