Boeing in the process of completing the 737 Max software update

Boeing Co. is working on the final details before applying to US regulators. review an anti-lock software update, related to two 737 Max model fatal crashes, a first goal of anchoring the world's best-selling aircraft to the ground.

However, the badessment of the proposed solution by the Federal Aviation Administration (FAA) has many steps. could be extended until Juneeven if there are no complications, said a person familiar with the case. Boeing must also convince the Beijing authorities in Brussels that the plane is safe. Canada has already indicated that it will not follow the recommendation of an FAA panel of experts that additional simulator training for pilots would be required.

Boeing has completed his updated software engineering test, and its technical and technical leaders were on board the final flight test earlier this week, said the executive director, Dennis Muilenburg, in a video message Wednesday night. Then he described a "certification theft", while Boeing prepares to send the final documentation to US regulators.

For this flight, Boeing will hand over a 737 Max to FAA pilots to test the design improvements that the company believes will ensure the system will never overwhelm flight crews, as it was the first time. case in two accidents the life of 346 people in total. The regulatory body will determine when the certification flight will take place.

"We are constantly moving towards certification"said Muilenburg, with a Max plane and Boeing Field, an airport south of Seattle, in the background. At the beginning of the day, Muilenburg was a pbadenger of a demonstration flight, observing the latest MCAS software update "working as expected under various flight conditions".

Muilenburg has beefed up Boeing's campaign to boost public confidence in the safety of the 737 Max and the design of the company's aircraft, after the collapse of two of its aircraft in five months. The Max, which debuted in May 2017, is the latest version of a family of aircraft from a single aisle that is Boeing's biggest source of profit.

In total, Chicago-based Boeing made 120 flights and spent 203 hours testing the new system, Muilenburg said. The campaign included a 737 Max 7 equipped with flight test instruments, as well as aircraft having departed a Boeing plant south of Seattle with updated software already installed.

The update is designed to make the anti-lock system less aggressive and avoid repeated commands that force the nose of the plane which has overwhelmed the crews of Lion Air and Ethiopian Airlines. In addition, the MCAS software, which means the Maneuver Increase System, would no longer be activated by a single faulty reading of the sensor.

The ultimate goal of Boeing is "Make the 737 Max one of the safest planes to fly"said Muilenburg.
