The bigger problem is the MCAS was only added to fix a major design fault, where by the aircraft would automatically pitch up when accelerating.
So with the MCAS disabled, the aircraft then runs the risk of stalling when accelerating.
I don't understand how design engineers would ever think a software workaround would be a suitable fix for what appears to be a major aerodynamic design flaw.
- ams6110 8y agoAll aircraft with underslung engines want to pitch up when accelerating. That's just physics. MCAS is there to counter pitch up at high angles of attack, caused by the aerodynamic characteristics of the larger, more forward engine nacelles.
- jussij 8y agoIt's not the pitch that is the problem, but instead the degree of pitch. This particular aircraft had a tendency to pitch so badly they had to install a software workaround to automatically catered for the behavior. And presumably it was so extreme they thought an automatic option was needed, out of fear the pilots on their own would not be able to handle the situation.
