Re: B737MAX Grounded Worldwide

Proper evaluation of MCAS 2.x requires a specific definition of the flight envelope that it is intended to operate in. So far, it is unclear what Boeing is doing to validate sensor data beyond “disagree,” which might not be quite enough given the high failure rate on the AoA sensors.
