So, let's see if I have gotten this right...? To improve the CAS estimate by an insignificant(?) 2-5kts, a vulnerability was introduced that could have a SINGLE sensor trigger a UAS, which by the QRH would have the pilots fly manually, in which case their life will be made a mess by the SAME sensor...?
As a mere PPL-I, I cannot fathom this. What am I missing?
As a daytime teacher of software engineers, I am beginning to suspect that this design decision, if confirmed true, will ever so sadly be useful in my teaching, together with the Apollo 1 fire and the Ariane 501 explosion...
