I read a similar article about this from a different news source. If I read it correctly animals can still be brought onboard but must be in a carrier and once airborne the dog can be removed from the carrier and held in the passenger’s lap. This seems like a pretty big loophole.
I apologize for not making my comments clear. What I was trying to say was the original Max design used only one AOA sensor for the MCAS. I believe it was the left one. If that AOA failed there was no way to switch to the right AOA nor was there any kind of comparator system to analyze which signal was correct. The plane indeed has two AOAs, but the MCAS only used the left one. The two crews never knew this because they were unaware the MCAS existed. To think that Boeing designed this system with a single point of failure is really hard to understand.
How did MCAS initially work?
Prior to being enhanced, MCAS relied on information from a single Angle of Attack (AOA) sensor to monitor the angle of the airplane. In the two accidents, a single AOA sensor gave incorrect information to MCAS, which caused it to activate. In both cases, MCAS engaged repeatedly when the sensor continued to incorrectly report a high AOA.. This is directly from Boeing.
