And the saga goes on. It remains inconceivable to me how they are able to certify a system that may, under the right circumstances, be flight critical and a single point of failure, and not be equipped with the required redundancy for that case. If a sensor disagree occurs and that takes the system offline, then it's not a viable safety critical system, that's an unnecessary add-on. So get that third vane in there and wired up and try again.
