                                                                                                                                                                          2019-06-08 20:50 宝丰-POS党建网

                                                                                                                                                                            美国国会议员称,波音公司早在2017年就已获悉波音737MAX机型飞行员预警系统存在问题,但该公司决定在2020年之后再解决该问题。

                                                                                                                                                                            据路透社6月8日报道,“2017年波音公司了解到驾驶舱内信号灯有故障,该信号灯在传感器发生故障时亮起,但决定把修复它的工作推迟到2020年。”

                                                                                                                                                                            报道称,美国国会议员彼得迪法吉奥和里克拉尔森7日通报了这一消息。他们上周五在新闻稿中说,波音公司于2017年11月决定推迟软件更新,直到三年后的2020年再来纠正迎角不一致警告缺陷。他们补充说,波音公司只是在印尼“狮航”发生事故后才决定加速纠正计划。

                                                                                                                                                                            波音发言人约翰德罗在电子邮件中表示,公司安全审查发现,迎角不一致警告缺陷并未对飞机的安全或运行产生不利影响。他表示, “我们在执行迎角不一致警告方面有所欠缺,为避免再次发生我们正在采取措施解决这些问题。”

                                                                                                                                                                            2019年3月10日,埃塞俄比亚航空公司的一架载有157人的波音737 MAX 8客机坠毁。而2018年10月29日,印尼狮航一架同样型号的航班也曾发生坠机。埃塞俄比亚航空的这起空难发生后,20多个国家和多家航空公司暂停使用波音737 MAX 8执飞。美国联邦航空局已禁止该型号系列飞机在美国领土上运行。

                                                                                                                                                                            调查发现,飞机失事可能是由于机动特性增强系统(MCAS)在运行中出现故障。波音公司目前正在解决这一问题并对飞行员训练方案进行更新。
