Static, dynamic, AOA, all of them.
I am merely SLF, but I do a LOT of industrial machine control systems work. I and my team spend a lot of thought and effort to detect when the sensors aren't making sense, because that is the number one cause of problems in that world. In my case it's usually just making a few hundred thousand dollars worth of scrap, not augering into terrain with a few hundred pax aboard.
It is not possible to make a 100% reliable sensor. For any measurement.
If that measurement is important, you need to validate it.
Always being aware that the validation may itself induce faults.
I will crawl back into my cave now.
