Boeing 737 Unable to Trim!! Cockpit video (Full flight sim)
Mentour Pilot
Mentour Pilot, a 737 captain, demonstrates in a full flight simulator why a Boeing 737 can become impossible to trim manually at high speed. He explains the jackscrew forces and the roller-coaster manoeuvre.
HN pointed to it during the 737 MAX discussions to show how hard manual trim is when severely out of trim.
