Regarding the STALL WARNING in NORMAL LAW, it is available, but the threashold is way below V ALPHA MAX, it is impossible for the A/C to reach this threshold and still be airborne. The ONLY way to get a stall warning in NORMAL LAW is for the AoA probe to break or be stuck to reach this threashold. The reason that it is on the FCOM is because it has happened before.
