I would start off by saying that there is a lot of false information in that Globe and Mail article. We actually prepared a response. Your question relates to a previous comment by Mr. Barsalou-Duval.
The aircraft does not rely on MCAS to be stable. This is a fallacy. The media has taken this and it's gone a little bit too far. Our push-back on The Globe and Mail includes an attempt to correct that fallacy, in that the MCAS system is simply a system that will increase the nose pitch-down moment on the aircraft to affect the feel that the pilot has in the control column as part of the stall identification system. The aircraft has been thoroughly tested with the speed trim system—which includes the MCAS system—completely inoperative and the flight characteristics have been found to be totally acceptable.
This is not an inherently unstable aircraft. Anything that you're reading out there that says that MCAS is there to prevent an aircraft from stalling or that it is otherwise saving the day on an “unstable aircraft” is simply untrue.
