We review the update plan Boeing to solve the faults of the MCAS in the Boeing 737 MAX 7, 8 and 9 after the more than known events.
Against the clock, but mainly focused on safety and meeting FAA expectations, FBI, EASA, world authorities, users and also all its current and future clients, Boeing has officially presented its update plan for the different systems and components that act when MCAS is activated as a flight protection process..
Preliminary Ethiopian Airlines ET302 accident report
Once the preliminary report of what would have happened in the accident at the Boeing 737 MAX 8 of Ethiopian, and I say there would be because we have to wait until the final report, which may take several more months., The manufacturer and airlines are preparing for the introduction of changes in this system to avoid future accidents.
In this preliminary report it was learned that the crew of flight ET302 carried out the necessary procedures and instructions indicated by the manufacturer Boeing that were implemented after the first accident of a MAX on the Lion Air flight., but this procedure did not allow them to regain control of the plane, despite trying at least four times by disconnecting the MCAS system.
MCAS Update
As we review in this post about MCAS, it is designed, in simple and quick words, to compensate for the climb attitude of the MAX in the event that certain parameters are exceeded to prevent it from entering into what is known as a stall, which could lead to risk situations depending on the stage of the flight..
Boeing has developed an MCAS software update to provide additional layers of protection if AOA sensors provide erroneous data.. The software underwent hundreds of hours of analysis, Lab tests, verification in a simulator and two test flights, including a flight certification test with representatives of the Federal Aviation Administration (FAA) on board as observers.
Additional layers of protection include:
- The flight control system will now compare the inputs from both AOA sensors. If the sensors do not agree with 5.5 degrees or more with flaps retracted, MCAS will not activate. An indicator on the flight deck screen will alert pilots.
- If MCAS is activated under abnormal conditions, will only provide one entry for each elevated AOA event. There are no known or anticipated failure conditions where MCAS will provide multiple inputs.
- MCAS can never command more stabilizer input than it can counteract the flight crew backing up the column.. Pilots will always continue to have the ability to override MCAS and manually control the aircraft. These updates reduce crew workload in non-normal flight situations and prevent erroneous data from causing MCAS activation..
Crew training
To obtain a Boeing type rating 737, pilots must complete 21 or more days of instructor-led academic training and simulator. Difference training between the NG and the MAX includes computer-based training (CBT) and manual review.
Boeing has created an updated CBT to accompany the software update. Once approved, will be accessible to all Boeing pilots 737 MAX worldwide. This course is designed to provide type-rated pilots with a better understanding of the Aircraft Speed Adjustment System. 737 MAX, including MCAS function, associated existing crew procedures and related software changes.
Pilots should also review:
- Flight Crew Operations Manual Bulletin.
- Updated Speed Adjustment Non-Normal Checklist.
- Revised Quick Reference Manual.
Boeing continues to work with FAA and other regulatory agencies on software update certification, which will allow in a time not yet defined, put back on flight line the most of 300 Boeing 737 MAX worldwide.
