How is the fix really a fix? If MCAS is switched off automatically, we have an aircraft without MCAS. Apparently MCAS is good for something in the first place, otherwise it would not be there. So the aircraft will then be operating at the brink of a stall and the pilots need to keep it in the air? ...

Re: Lion Air 737MAX8 Crashed Jakarta to Pangkal Pinang

For the A320, in the event of a complete loss of electrical flight control computer signals, the airplane reverts to a mechanical mode. The side stick is inoperative, pitch is controlled via pitch trim wheel, roll and yaw are controlled through the rudder pedals. http://www.a320dp.com/A320_DP/fligh...
