More AOA sensor info!

- Operating Range 120º, limited by fixed stops.
- Balanced (= static it could take any position).
- Contains a dual purpose damping motor, damping the rotor in opposite direction of movement
created by Eddy Currents with a torque proportional to the speed of rotor movement, with a breakout force of 0.04 Nm.
- Damping motor can also be used on GND for test purposes (positions AOA sensor in a pre-determined test position)
- Internal heating element 115 VAC, 400 Hz; operating temp. 120 ºC.

For Audible Stall Warning I could find:

- Normal Law - AOA > 23º.
- ALT Law & Clean - AOA > Valued function of Mach number.
- ALT Law & SF - AOA> Valued function of SF position.

Just for a moment went into the B777 books too, for reference only not for pleasure
far less information but everything related seems to be unvalid if CAS< 30 Kts.
