Long Before Boeing 737 Max Crash, Ethiopian Air Pilot Warned of Dangers
In the flight just before the Lion Air crash, with the same airplane, the MCAS activated wrongly, and the pilots shut off the stab trim and landed safely.<p>The MCAS system was known about after the Lion Air crash, and it baffles me why pilots wouldn't have known about successful corrective action taken on the previous flight. After all, I read about this in the newspaper. It wasn't a secret.<p>It's hard to tell from the newspaper accounts, which often leave off crucial details, but it seems the electric trim switches (on the control column) override the MCAS commands. So the way to recover is to set the electric trim switches to nose up, turn the trim system on at the cutoff switches, wait until it's trimmed out properly, then turn it off via the cutoff switches and let go of the electric trim switches.
