Further to the issue of the AOA.  The Advanced AOA in my Legacy is =
useful.   Failing any other stall warning device and lack of any =
pre-stall buffet, this is the only electronic device to provide a =
warning.   It does not require a stall to setup, I just re-did my =
calibration last week and no stall is required.

A secondary feature is the ability to adjust approach speeds more =
accurately reference landing weights which vary widely.

Another feature is that the AOA from Advanced has a pinout to connect to =
a stick shaker, bell, warning horn or any other device to signal a high =
angle of attack.

My guess is that the risk of stall is not high in normal smooth day vfr =
operations but probably useful when problems develop, the attitude goes =
wrong and disorientation or other upset occurs.  At least something =
besides your brain would be able to signal that a stall is imminent.  =
There is nothing else in the Legacy panel or flight characteristics I'm =
aware of that warns of such a situation so I believe it is a wise =
addition to the panel.

So, don't let anyone tell you that installation of this particular =
device requires stall testing.  Just not required.
