When dealing with AoA sensors it is very important to consider how it
is to be used. If it is intended to be a Go - NoGo stall warning
device, that is one thing. If it is intended to be used to measure
and be proportional to a range of AoA that is quite another. The
mounting becomes quite critical because the airflow may be such that 1
degree of AoA change does not translate into 1 degree of sensor
movement (in the case of a vane for example) . As a young flight
control engineer I learned this the hard way when an AoA vane mounted
near the nose of a test vehicle actually changed 5 degrees for every
degree of AoA change of the aircraft.

Good point.

Lets say that you will be interested in only stall, min sink, and best L/D
at each flap setting. Can it be calibrated for that?
