One could argue that, even without indication of stall and SW AoA's, having an indication of actual AoA is better than nothing. Does anybody know if and how the BUSS addresses that problem?
P.S.
AFAIK the BUSS indication of SW and Stall AoA does not change with Mach. Is is a function of flap/slat configuration only. The stall warning AoA with all three ADR's off is 8.6 degrees in F/S configuration 0/0 . Above FL 250 the pilots are instructed to fly pitch and power and not use the BUSS.
