The lion air crew had the benefit of a jump seat pilot who I understand helped fix the problem.
Yes indeed and the crew of the Ethiopian aircraft had benefit from knowledge of the Lionair crash and information provided by Boeing. Sunfish I enjoy your input on this forum but with the greatest respect, unless you are a professional pilot who goes to the sim every few months to be trained and checked and experience what this entails and what is expected of us then you cannot possibly understand the subtlety of the crews actions. I don't feel qualified to post on legal forums or medical forums so I don't.
Any system that winds on trim countering pilot input (while pilots are trying yo sort out another failure giving unreliable speed and constant stick shaker) needs to be disabled from all aircraft.
Do you know what a tail-strike avoidance system is? Should they be disabled?
