The other condition has its root in the disconnection of Speed Trim, MCAS, Autopilot, and Flight Directors should the two Angle of Attack systems disagree. Should the AoA monitor trip, Speed Trim, MCAS, and more importantly, Autopilot and Flight Directors disconnect, it puts a crew in a very tight spot as the difficulty of such approaches are high (they require special crew training and certification). You need all the tools you have in such approaches and don't want a sudden disconnect of the Autopilot and Flight Directors combined with Speed Trim warning, followed by AOA, IAS and ALT DISAGREE. It would then result in an AOA DISAGREE warning, but the Autopilot and Flight directors would stay on and IAS and ALT would still get the required AoA corrections. ./cache/blog-dshr-org-4867.html ./txt/blog-dshr-org-4867.txt
