What about the causes that motivated the thread opening? Any more known?
Remember the Air XL A320 that was being flight tested in Spain by Air NZ crews and crashed during stall testing due to frozen sensors. Ok, it was after power washing and water froze in a hidden area. It was unforeseen; but then how many accidents/incidents are caused by unforeseen matters? Still quite a few.
It's one of those issues with sensors & computers. Even in cars, a faulty sensor in a catalytic burner can cause the engine not to start. Things in FBW flight controls are more critical. How possible is it to by-pass such inhibiting sensors; if you can even trouble shoot to the root cause?

The Air XL A320 crash was caused by pilot error, nay gross stupidity.
The test schedule was VERY clear that the AOA sensor check MUST be conducted at or above 10,000 feet AGL. The damn fool (not a qualified test pilot) conducted the test at low level where the result of a failure was fatally predictable.
Every test can either pass or fail, that is why they are on the test schedule. The purpose of the test was to check that the AOA sensors were working correctly - the test failed.
DUH.

I believe that it is necessary to monitor the pressure sensors of statics.A device can be to connect in parallel
sensors (this is 0-5 volts, LPF) devices from both sides, write everything to a computer, and then conduct an analysis.
Suppose we carry out such a study on about 100 aircraft.

Sorry, I probably misused the term "sideslip". The static pressure sensor is more susceptible to the shadow from the fuselage (the airplane is flying along the COG). The measurements will give, I hope, a more complete picture of the static pressure on the right and left.
