Standard procedure of flying the plane—apply trim to maintain neutral stock force. Yoke gets heavy as the trim inputs are made, counter with manual electric trim with the readily thumbed switches. Not a procedure—it’s called flying. Also, PULL THE POWER BACK. If you have no other means of controlling speed, leaving the power at TOGA is not helping. The problems only get worse with speed.
It wasn’t the pilots that crashed to planes, but they could have saved it.
Can you guaranty that manual electrical did work 100% in the Ethiopian crash? Do you have an explanation for why manual electrical trim stopped several times at the same angle, while trying to trim back from the MCAS action?How about, does manual electrical trim really stop the movement commanded by MCAS?
I do not want to exclude the possibility that the pilots may have been able to stop the frame from crashing, but to declare that they were definitely able to refrain from crashing, is not yet supported by the evidence available at this time.
An important difference between MAX and earlier 737 versions is, that on earlier versions automatic trimming (be it STS, Mach Trim, autopilot, whatever), automatic trimming is stopped
when an opposite movement is made on the control column. Which makes sense: if the auto systems are commanding nose down, and the crew want to go nose-up by pulling on the yoke, it makes sense to stop the opposite trimming.
However with the introduction of MCAS, as a
"feel-enhancement" system, that is now no longer the case. Some auto trimming is still stopped by control column movement, but some auto trimming is not (MCAS). This introduces a complete new level of complications in auto trimming behaviour, and associated misunderstanding by existing 737 pilots.
Is this clearly explained in the 90 minutes iPad conversion course? Probably not, since MCAS was not part of that course. One would expect that something like this, which goes every natural 737 pilot feeling should be explained (and trained . . . !) thoroughly.
