This is a seriously misleading characterization of the 737 Max. If you read https://theaircurrent.com/aviation-safety/what-is-the-boeing-737-max-maneuvering-characteristics-augmentation-system-mcas-jt610/ https://theaircurrent.com/aviation-safety/what-is-the-boeing... (the source of the article that 'acqq is selectively quoting) you will learn the following:
> MCAS is “activated without pilot input” and “commands nose down stabilizer to enhance pitch characteristics during step turns with elevated load factors and during flaps up flight at airspeeds approaching stall.
> Since it operates in situations where the aircraft is under relatively high g load and near stall, a pilot should never see the operation of MCAS.
In other words, the aircraft does not need MCAS for stability during flight in anything but exceptional circumstances. Normal flights should never have MCAS active.
This is not remotely similar to the aerodynamics of a fighter jet.
MCAS is a software mechanism designed to prevent stalls in extreme circumstances that can be overridden with the same method used to disable auto trim on previous models of the 737. The A320 has software to prevent phugiod motion in exceptional scenarios, except the A320's mechanism cannot be overridden by the pilot.
I don't care if you choose to never fly on a plane again, but don't spread this misinformed hysteria.
- tigershark 8y agoI think that the advice that you just gave to the parent post to not spread misinformation should be applied to your post. In the previous model it was perfectly fine to just tilt up to override that system. We have the sad proof that in the new model it is not enough given that the lion air pilots tried to do it for 26 times in 13 minutes. In a 2 months old plane. Given that 300 people already lost their life I will avoid flying on this plane and I’ll urge everyone to avoid it. If you are really keen to fly on it then please be my guest, but don’t you dare spread misinformation saying that this plane is perfectly safe and the accidents happened only because of the pilots or of the airline maintenance. I’m really wondering what are your vested interests in Boeing since you are polluting this thread with lies trying to cancel any Boeing responsibilities.
- twtw 8y agoThe comment you are responding to addresses the claim that the 737 max is not passively stable. It is less safe than other aircraft, but not because it requires active control for stable flight in any manner comparable to a fighter jet. I'll direct you to some portions of my other comments that you seem to have overlooked: > airlines and pilots were not informed well enough about MCAS > previous auto trim systems could also be "out muscled" just by pulling back on the yoke without actually switching on the manual override. ---- > polluting this thread with lies I'm pretty sure everything I've posted on this thread is either true or obviously an opinion. If some things are not true, please point them out specifically so that I can correct them. Nowhere have I said that the lion air 610 accident only happened because of poor maintenance or pilots actions, but it is undeniably true that with different pilot actions and aircraft maintenance the accident would not have occurred.
