Whoops! According to the NY Times,
“The situation in this case is further complicated by Boeing’s installation of the system, which the company did without explaining it in the new model’s operating manual. So the pilots might well have been unfamiliar with it.
In a statement, Boeing said it was confident in the safety of the Boeing 737 Max, and added, “While we can’t discuss specifics of an on-going investigation, we have provided two updates to operators that re-emphasize existing operating procedures — the series of steps required — for these situations.”
If the pilots of Lion Air 610 did in fact confront an emergency with this type of anti-stall system, they would have had to take a rapid series of complex steps to understand what was happening and keep the jetliner flying properly. These steps were not in the manual, and the pilots had not been trained in them.”
