Outstanding question by Chris...
The problem is not using two sensors. The problem is not simply using one sensor, but alternating between the seats in the cockpit, and not telling either of them about the system and how it worked, and then disconnecting the column switches they had used for thousands of hours, and then...... and then.....
I will take a huge bet that if every Max pilot back in 2017 had to read a description of MCAS and potential problems if an AoA vane went south, and /or had a stick shaker going and various caution lights indicating airspeed problems or yada yada, and even best! a MCAS light! Imagine that?. How many crashes?
Good grief!
The pissant cert thing about stick forces is the most tiny problem in this mess. Besides obvious aero problems due to the new motors and their mounting, the crude attempt to meet FAA cert using a crude kludge and possible FAA negligence passing the cert, the failure to tell ME, the guy that has to get 150 folks to Topeka, Kansas is bordering on criminal.
The lawyers of the lost souls are gonna have a field day.
Gums sends....
