" We're working with customers and regulators around the world to restore faith in our industry and also to our commitment to safety and to the trust of the flying public, Mike Sinnett, Boeing vice president, said in previewing the changes to pilots, reporters and regulators at its facilities in Renton, Washington.
Many of the details behind Boeing's plan to fix the Max have come out over the last two weeks.
Among the notable changes to the MAX flight controls:
- CAS automated flight control system, will now receive data from both angle of attack sensors, instead of just one.
- Boeing will be an indicator of the flight control display when the angle of attack sensor disagree.
- There will also be enhanced training required for all 737 pilots so they are fully aware of how the MCAS system works and how to disable it if they encounter an issue.
"We're working with pilots and industry officials," said Sinnett. "We have two hundred of them today in our Renton facility and we will be spending time with today to explain the updates we are making to the 737 max, to get their input and earn their trust." the end of this week, Boeing plans to send the software updates and plan for enhanced pilot training to the Federal Aviation Administration for certification approval. The FAA's approval process has raised questions in the industry and is the subject of a Senate hearing Wednesday afternoon. Industry officials believe it could take the FAA up to two weeks to certify the changes.
After the FAA approves the fix, Boeing said it will send the software update to customers. It takes a few days and more time for training and testing, the company said.
Still, the FAA and other regulators around the world need to sign off on the safety of the 737 fly and carry passengers. Some analysts believe that will take a minimum of six weeks and up to 1
"Not all customers wish to include this feature on their primary flight display, so it is offered as a customer-selected option," Boeing said. in a statement
Southwest Airlines, which has 34 of the Boeing 737 Max planes in its fleet, more than any other US airline, said it was "encouraged" by Boeing's Wednesday proposal.
"Boeing's software update appears to add another layer to the MAX aircraft's operation," said Bob Waltz, Southwest's chief pilot. "We look forward to the FAA's final guidance and will fully comply with any modifications and additional training requirements to strengthen the reliability of the 737 Max."
