بوينغ “حجبت معلومات” عن طائرة ماكس ٧٣٧

November 14, 2018 - Boeing failed to tell airline pilots about features of a new flight-control system suspected of playing a role in the fatal crash of an Indonesian 737 MAX plane, according to pilots who fly the jet in the U.S.

Pilots say they were not trained in new features of an anti-stall system in the aircraft that differ from previous models of the popular 737.

The automated system is designed to help pilots avoid raising the plane’s nose too high, which can cause the plane to stall, or lose the aerodynamic lift needed to keep flying. The system automatically pushes the nose of the plane down.

But if that nose-down command is triggered by faulty sensor readings – as suspected in the Indonesian Lion Air crash – pilots can struggle to control the plane, which can go into a dive and perhaps crash, according to a Boeing safety bulletin and safety regulators.
