hcs_$reboot shares a report from CNBC: Boeing previewed its software fix, cockpit alerts and additional pilot training for its 737 Max planes on Wednesday, saying the changes improve the safety of the aircraft which has been involved in two deadly crashes since October. By the end of this week, Boeing plans to send the software updates and plan for enhanced pilot training to the FAA for certification approval. After the FAA approves the fix, Boeing said it will send the software update to customers.
Among the notable changes to the MAX flight controls:
- The plane’s Maneuvering Characteristics Augmentation System, or MCAS, automated flight control system, will now receive data from both “angle of attack” sensors, instead of just one.
- If those disagree by more than 5.5 degrees, the MCAS system will be disabled and will not push the nose of the plane lower.
- Boeing will be adding an indicator to the flight control display so pilots are aware of when the angle of attack sensors disagree.
- There will also be enhanced training required for all 737 pilots so they are more fully aware of how the MCAS system works and how to disable it if they encounter an issue.
