Boeing Co said on Sunday it was finalizing the development of a software upgrade and a revision of pilot training for its 737 MAX, the plane that has suffered two fatal crashes in the last five months.
The updates are intended to address how the aircraft’s flight control system – MCAS (Maneuvering Characteristics Augmentation System) – responds to erroneous sensor inputs, the plane maker said.
A 737 MAX 8 operated by Ethiopian Airlines crashed shortly after take-off on March 10, killing all 157 on board.
