Boeing unveils software updates to embattled 737 MAX jet

Details of the updates, per Boeing's website:

• The MCAS will now compare inputs from both angle-of-attack (AOA) sensors. If the sensors disagree by 5.5 degrees or more with the flaps retracted, MCAS will not activate. An indicator on the flight deck display will alert the pilots.
• If MCAS is activated in non-normal conditions, it will only provide one input for each elevated AOA event. There are no known or envisioned failure conditions where MCAS will provide multiple inputs.
• MCAS can never command more stabilizer input than can be counteracted by the flight crew pulling back on the column. The pilots will continue to always have the ability to override MCAS and manually control the airplane.

What's next: Boeing plans to send the software updates and new plans for pilot training to the Federal Aviation Administration for review by the end of this week, according to CNBC.

• Reality check: The new updates are nowhere near close to getting certified, given there numerous ongoing investigations by multiple U.S. and international agencies.
• The FAA itself is currently under scrutiny for not grounding the 737 MAX jets faster and for delegating certification activities to Boeing.
