The above is the procedure of the aircraft that doesn't have BUSS.
The above is the procedure listed in 2014 FCOM. If you compare the old one and the new one, you will notice that the info about STALL warning protection is removed. You must be aware that a modification has been carried out routing the AoA through IR instead of ADR enabling STALL warning even with all ADRs off. So, I don't think keeping one ADR on is to provide STALL warning. For melting of the ice.....ok...maybe..
Yes, I remember I think they did that before BUSS. So that if all three ADRs unreliable they can be switched off. Stall warning will come through IR anyway.
