Why limit to cargo? MCAS is just a pilot aid that changes the type rating of the aircraft. It was designed to avoid that change but we are witnessing why you do not hide critical subsystems from pilots or regulators. So reveal the system, force a new type, require training. Revealing the system will highlight the obvious flaw of a single air speed foil and aerodynamic issues of the elevator trim. Fix that and you have a perfectly flightworthy plane. But money is the motivator here and the MAX is starting to look like a loss leader. Big question here: what will southwest do if the MAX requires a new certification by pilots? Stick with Boeing (meaning Boeing pays for this mistake) or flip entirely to airbus (and Boeing loses a major customer)
