gums thanks for the reply jimtx i did not read all the pages so excuse me.. i was just wondering if there was something more to this. just wanted to know if the MCAS system has its own non controllable trim motors that we cant shut off in the cockpit!!! I know how its is supposed to work based on what I have been trained on. I flew one on tuesday and had NO issues. And by the way 20k plus years and hours in the 737!
