Boeing Targets December For New MAX Deliveries - AVweb

One of the many items on the original list is how much authority to grant MCAS. It started out as a specialty trim system, to keep handling characteristics similar to old 73’s, but ended up with enough authority to crash two airplanes, as it didn’t recognize the faulty input from a failed sensor.
The details aren’t available, but I’m going to guess that full MCAS trim can be outflanked by yoke displacement.
