Regarding how to ' handle' faulty sensors re inertial/GPS systems

See pages 40 and 41 on 787 v 777 features. One wonders why such was not incorporated in MAX ?

•Calculated from angle of attack and inertial data
-AOA –voted dual sensors plus inertial data
-Accurate Coefficient of Lift (CL)
-Airplane Mass from FMC -Validated after Takeoff
•Algorithm developed for enhanced stall protection
•Avoid displaying data known to be bad
-Loss of valid voted VCAS
= Display synthetic airspeed VSYN
-Loss of valid voted PSTATIC= Display GPS altitude
