Boeing presented hundreds of airline journalists, pilots, and airline executives with the long-awaited changes to the flight system of its 737 MAX in the Renton stronghold on Wednesday in two air disasters that left 346 people dead. month apart.

The pilot regains control

Boeing Wednesday launched a charm offensive to convince that the corrected version of MCAS anti-stall system equipping the fleet of 737 MAX - implicated in these accidents - was now operational. The intervention of the MCAS will be more transparent for the crew and the pilots will be able more easily to circumvent it in case of problem, explained in substance Boeing, which will present this new version to several hundred professionals Wednesday to have their opinion.

According to the manufacturer, the new version of the software was subjected to "hundreds of hours of analysis, laboratory testing, flight simulator checks and two test flights, including a certification flight with representatives of the FAA (the agency responsible for giving the green light to all that flies in the United States, ed) aboard as observers ". The goal is to "reduce the crew's workload in abnormal situations and prevent the MCAS from activating because of false data," Boeing said. The FAA and other regulators have yet to certify these changes, he said.

Boeing also planned to better train pilots in the subtleties of the MCAS and the 737 MAX whose engine modifications significantly changed the behavior.

Suspicions of collusion

Later in the day, Dan Elwell, the FAA's interim leader, who until then had been a reference in much of the world, will have to try to explain to US senators why the FAA has been slow to make the decision. to nail down the MAX fleet after the tragedy of Ethiopian Airlines.
