The new Embraer Jets have a Pitch Limit Indicator. Its a mustach type symbol that is displayed with reference to the aircraft pitch symbol and uses the adi pitch scale to show margin in degrees to the AOA limit. Its colour matches that of the Low speed awareness tape and when you reach the AOA limit it would be in line with the pitch symbol and the stick shaker will fire. This will also trigger AOA limiting in the fly by wire system to prevent any increase in AOA. The nornal flight referance symbol is a Flight Path Angle used in all phases of flight except take off. so AOA can be seen as the diffrence between FPA and Pitch.
