Yes, especially since there are only 2 AOA sensors so you can't know which one is incorrect by comparing to a third sensor. I've read that it's possible to derive AOA from other sensors but don't think these aircraft have that ability.
- heyjudy 8y agoSerious lack of redundancy in a life-safety critical-system. It should have: - 5+ AOA sensors of different types - discard any sensor values that are stuck or providing incorrect readings - have a spray, heating system (some do) and camera system for automatically deicing and verifying AOA sensors in-flight Without a camera system to verify sensors, crews won't have a definitive way to know if they're getting true or false information from clogged pitot, stuck AOA or malfunction.

- kwhitefoot 8y agoYou should always have at least three and preferably an odd number of similar sensors so that you can get at least a vague idea of consensus. The British Royal Navy rule was: take one chronometer or three, never two because with two you will always be unsure which one is correct while with three you can, usually, just average the two that are closest together and regard the third as an outlier.
