While it's nice that Sully has a 737 type I suggested him because he has the gravitas to reassure the public. You could put almost any airline pilot in the seat in the MCAS envelope and have him...

Some previous threads above hint at the answer. Unless we don’t know about some egregious handling issues the FAA and Boeing should about face and decide to turn MCAS off. If there is something more...

It is a question of dispute. Who do you allege was trying to keep it a "secret"? What is a fact is that Boeing did not realize who they were selling airplanes to.

A secret to who? The Brazilian Certifying Authority knew about it and had it as a Cat B training item. Might be other countries also. It appears the FAA knew about it and bought off on not including...

So what should the pilots be afraid of once the electric trim is dissabled and MCAS is no longer there to protect them. Shouldn’t that be in your procedure? Hint: I’m one of the guys that think MCAS...

So the bird is not unstable. I would suppose that and have always thought that. Why is MCAS “desirable”? If the bird became light in pitch in a steep turn that wouldn’t bother me. What envelope would...

What "intentional secrecy" are you referencing. I think the use of MCAS was not hidden from anyone. Boeing (Chief Technical Pilot Forkner) appears to have put it in the Brazilian certifying...

He quotes Brady in his article but expresses uncertainty about whether he is correct. Yes you have to wonder how that pencil whip actually performed in the windup turns.

I almost quit reading after "stall prevention" and managed to grit my teeth through "thrustline" but if he doesn't know that Brady is giving the correct reason for MCAS by now, absent any stunning...

Why is MCAS not needed if the autopilot is on. Does longitudinal stability not apply to the autopilot? Or does everyone know the MCAS protected regime is not on where the autopilot could be engaged?

That is what I was trying to say. A little lightening of stick force/gradient in some rarely visited regimes might not be a problem for most pilots especially if it was noted in their training. But...

There is a lot I don't know about the aero of the MAX but I don't think the original MCAS was put there for "unacceptable" stick force. It was put there for non linear stick force which would be...

It would be interesting to find out what Forkner told the Brazilian Certifying Authority, ANAC, about MCAS and how that was implemented as a category "B" training item for GOL's Max pilots. MCAS is...
