Chief executive joins a test flight for the demonstration of updated anti-stall software

Seattle - Chief executive Dennis Muilenburg joined a test flight on a Boeing 737 MAX 7 for a demonstration of the updated anti-stall software intended for Boeing's grounded MAX series jets.

The anti-stall software of the Boeing's new generation single-aisle jets is under scrutiny after two deadly crashes in Ethiopia and Indonesia.

Boeing and the U.S. Federal Aviation Administration are accused of disregarding safety flaws during the certification process of the aircraft.

Boeing hopes to convince civil aviation regulators to allow its grounded jets to fly again with the new software update that it's currently working on.

On April 3rd, Boeing carried out a flight with a Boeing 737 MAX 7, which is also in the certification process, to test the new software under different scenarios with failure conditions.

Boeing Chief Executive Dennis Muilenburg also attended in the flight and he was briefed by the technical personnel about the outcomes of the tests.

It can be seen as a message from Muilenburg to the world for the safety of Boeing 737 MAX jets.

“The software update worked as designed, and the pilots landed safely at Boeing Field,” Boeing said in a statement.

The aircraft manufacturer has also said that it would conduct additional test flights to demonstrate all addressed certification requirements are met.

Boeing will submit the improved anti-stall software of the MAX series jets in the coming days for the FAA review and approval when completed. The manufacturer was supposed to submit it last week, but it was delayed as additional work required.
