Another airplane that fights the pilot if one AOA sensor is bad: Cirrus Jet

In another triumph for American engineering, it seems that the Cirrus Jet‘s stick pusher activates if a single AOA sensor fails mechanically (FAA Emergency Airworthiness Directive 2019-08-51). The system isn’t quite as badly designed as the Boeing 737 MAX’s silent gradual pusher, but it is nowhere near as robust as the early 1990s design on the Pilatus PC-12 (Swiss engineering). An important difference is that it is obvious to the pilot(s) when the Cirrus system is operating and the disconnect button is right on the yoke (just the usual A/P disconnect button).
