Airbus takes the AoA information along with the rest of the air data, sends it to the Flight Augmentation Computers which then compute and display relevant information on the PFD speed tape:
Green Dot (max l/d),
Vls (lowest selectable speed w/ autopilot),
Alpha Prot (below which sidestick requests an AoA, bank limited to 45, speed brakes retract, a/p disconnects, pitch up trim inhibited),
Alpha Max (cannot be exceeded in normal law)
Additionally the Alpha Floor function utilizes AoA and other parameters to determine when to apply TOGA power to extract the aircraft from a dire low energy situation.
Airbus has recently developed the Back Up Speed Scale, which in the event of a triple air data failure replaces the airspeed tape on the PFD with an AoA scale of a conventional design. Keep it in the green range, respect the chevrons. So simple I could do it.
