It's worth noting that there are other more engineering reasons it could be tricky to use both. An aircraft in a side slip will show different reading on the left and right sensors. Also, there are failures which are likely to impact both at much the same time, icing being a big one.
- mhandley 8y agoAgreed. Boeing's revised MCAS will disable itself if the AoA sensors disagree by more than 5.5 degrees when MCAS activates, or a sustained difference of more than 10 degrees otherwise. This is to take into account the fact that the sensors disagree to some degree in normal circumstances. These are fairly relaxed limits, but does demonstrate that a reasonable solution is possible.
