  Boeing said Thursday that it has completed software update and tests for 凯发k8娱乐网址737 Max planes.   波音周四表示,已完成737Max机型的软件升级与测试。   "Boeing has completed development of the updated software for the 737 MAX, along with associated simulator testing and the company's engineering test flight," said the U.S. top aircraft manufacturer.   It added that it has flown the 737 Max with an updated flight control system, the Maneuvering1 Characteristics Augmentation System (MCAS), for more than 360 hours on 207 flights.   Investigators2 believed a flaw in the MCAS software was a contributory factor to the crash of the Ethiopian Airlines Boeing 737 Max plane en route from Addis Ababa to Nairobi, Kenya, on March 10, 2019, which killed all 157 people aboard.   The crash bore alarming similarities to the circumstances surrounding an earlier fatal air accident involving another 737 Max aircraft of the Indonesian Lion Air, which went down in Indonesia in October last year and killed all 189 passengers and crew on board.   The two deadly air crashes have plunged3 Boeing in the worst crisis in its history, and the company has been under mounting pressure to improve air safety by updating the flight control system of the 737 Max planes.
