Usually, this procedure is to press and hold the autopilot disconnect button on the yoke&amp;#x2F;stick or the trim switch and then, later, deactivate the system. The pressing of the autopilot disconnect button or trim switch is a &amp;#x27;memory item&amp;#x27;, meaning that it should be performed immediately, without a checklist, upon recognizing that there&amp;#x27;s a problem. Previously, this malfunction has been a rare occurrence, and so can be startling to pilots or not immediately recognized. I&amp;#x27;ve seen pilots fail to apply the procedure and crash many times in the simulator, even after being told it was coming. It could be said that the pilots of the Lion Air aircraft and, potentially, this Ethiopian aircraft should have known the procedure and reacted properly, however, for Boeing to put them in this situation is, in my opinion, also quite hazardous. With so many hastily trained and low-competence airline pilots flying around, should we really rely on them to understand the technology and react properly?</text></comment>
