<div>This youTube explains what the handling of the 737 can get a bit dicey under certain conditions and that pilots need to practice it. Don't remember if someone already shared this, or YouTube suggested it after I watched something else.<br></div><div><br></div><div><a href="https://www.youtube.com/watch?v=TlinocVHpzk" rel="nofollow" target="_blank" class="">https://www.youtube.com/watch?v=TlinocVHpzk</a></div><div><br></div><div>I wonder, if in addition to the problems with faulty sensors, and difficulty over-riding MCAS, if the flight simulators accurately handle the situation <span>difficulty actually moving the controls at</span> high speed at low altitude (high air pressure).</div><div><br></div><div>Yes, I saw a TV clip about Ralph Nadar and niece and law suit.</div><div><br></div><div>As an aside, the latest generation of military planes have flight surfaces that allow them to maneuver in dramatic manners. This can be good if trying to evade hostile planes/missiles. It would be very difficult for a good pilot to control them without a lot of computer assistance. <br></div><div><br></div><div><br></div><div><br></div><div><br></div>
