>>>On the issue of icing, as far as I am aware, none of the AOA systems are
immune, including the Proprietary Software and the Lift Reserve systems.
However my pitot tube is heated.<<<


The PSS AOA wing ports are located aft of where icing will occur provided 
they're installed according to directions.  Ice will build up on the LE back 
to about 7-8% of chord, dirt, bugs and other contaminants go back to about 
11%.  The AOA ports are supposed to be located 15-40% of the MAC aft of the 
LE, well out of the icing area.  Still, staying out or getting out of the 
icing conditions should be first priority, regardless of how well aircraft 
appurtenances are protected from them, IMHO.  FWIW.
