Boeing announced Thursday that it has completed the update of the software of its 737 Max aircraft, a key step in the return to service of the aircraft after the aviation authorities had failed jet aircraft in the world as a result of two fatal accidents.
Boeing has announced plans to work with the Federal Aviation Administration to plan a certification flight.
The actions of the aircraft manufacturer increased after the publication of his statement, recording a rise of 2.8% at the end of the session.
Nearly 400 Boeing 737 Max aircraft fleets were stopped by the aviation authorities in mid-March after a second fatal crash of the aircraft sold quickly in less than five months. The investigators of the latest accident, in Ethiopia, have put forward an automated anti-stall system, which pilots fought in the final minutes of both accidents.
The system, known as MCAS, pushes the nose of the plane repeatedly if the aircraft software detects that it is taking off. It's a normal position to avoid a stall, but it can be catastrophic if the plane is not actually in stall. Collision investigators implicated the system in the crash in Ethiopia and in another crash of the 737 Max in October, explaining that it had been triggered by bad data provided by the sensors.
On Thursday, Boeing announced that it had flown the 737 Max with software updated for 360 hours on 207 flights. As planned, it also provided updated training material to 737 Max pilots.
Some pilots complained that they did not learn that the MCAS system was even on board the aircraft until the Lion Air 610 crash in October killed 189 people. In order to move from an older model of Boeing 737 to 737 Max, pilots reported receiving computer or tablet training, some courses lasting less than an hour. MCAS has not been mentioned.
Boeing's lack of disclosure has attracted the attention of lawmakers as well as pilots. FAA Acting Chief Daniel Elwell, at the House Aviation Committee hearing Wednesday, said the new MCAS system should have been included in the pilot's manuals.
The way the Boeing 737 Max has obtained FAA approval is the subject of several federal and other lawmaker inquiries.

Boeing completed the development of the updated software for the 737 MAX, as well as the associated simulator tests and engineering test flight of the company. To date, Boeing has piloted the 737 MAX with updated MCAS software for over 360 hours on 207 flights.
Boeing now provides additional information to respond to requests from the Federal Aviation Administration (FAA), including detailed information on how pilots interact with aircraft controls and displays in different flight scenarios. Once the requests are processed, Boeing will work with the FAA to schedule its certification flight test and submit the final certification documentation.
"With safety as our top priority, we have completed all technical test flights for the software update and are preparing for the final certification flight," said Dennis Muilenburg, Chairman of Boeing's Board of Directors. . "We are committed to providing the FAA and global regulators with all the information they need and correcting it, and we are making steady and steady progress, and we are confident that the 737 MAX, with the updated MCAS software, will be the only one. One of the safest planes Accidents have only intensified our commitment to our values, including safety, quality and integrity, because we know that life depends on what we do. "
In addition, Boeing has developed enhanced training and education materials, which are currently under review by the FAA, global regulators and airline customers to facilitate re-commissioning and long-term operations. This includes a series of regional customer conferences held around the world.
Correction: This story was updated to note that Boeing did 207 test flights and not 270.
