知情人士称，初步调查结果表明，为飞机两台发动机提供燃油的开关被关闭，导致飞机在起 飞后不久便明显丧失动力。据几名驾驶该型号飞机的飞行员介绍，飞行员可以通过开关启 动、关闭以及在某些紧急情况下重启发动机。 知情人士还表示，这些开关在飞行过程中通常处于开启状态，目前尚不清楚它们是如何以及 为何被关闭的。知情人士还透露，目前尚不清楚这是意外还是故意行为，以及是否有人试图 重新打开这些开关。 有分析认为，如果这些开关真的被关闭，这或许也能解释为何飞机的应急发动机，即冲压空 气涡轮似乎在飞机坠毁前瞬间启动了。据介绍，冲压空气涡轮能在飞机所有发动机失效的紧 急情况下，为飞机关键系统提供动力。 前航空公司飞行员、现任咨询公司"安全操作系统"首席执行官的约翰·考克斯解释称，关闭 开关会切断发动机的燃油供应，如果同时关闭两个控制开关，就会同时断掉两个发动机的燃 油供应，"发动机可能在非常短的时间内失能。"考克 斯 说，不能排除有人故意移动开关的 可能性，"但也有可能是误碰。可能有一个发动机出现故障，飞行员试图拨动控制该发动机 的开关，结果误触了另一个正常发动机的开关。" 据红星新闻、澎湃新闻等媒体报道，知情人士10日透露，目前 ...

Core Insights - The investigation into the crash of Air India Flight 171 has revealed that the emergency generator was operational at the time of the incident, raising questions about the normal functioning of the aircraft's engines during takeoff [1] Group 1: Investigation Findings - Investigators have identified that the emergency system, known as the Ram Air Turbine (RAT), was deployed, which serves as a backup generator for the aircraft [1] - The RAT is designed to activate automatically in cases of dual engine failure or when hydraulic system pressure is critically low, as well as in situations where cockpit instruments lose power [1] - The investigation is focusing on whether there was a loss of thrust or descent prior to the crash, although it remains unclear whether the emergency system was triggered by engine issues, hydraulic system failures, or other factors [1] Group 2: Industry Context - Dual engine failure in commercial aviation is extremely rare, given the advancements in engine efficiency and reliability [1] - The findings from this investigation may have implications for the Boeing 787 Dreamliner and its operational protocols, particularly concerning the reliability of its systems [1]

Core Viewpoint - The crash of an Indian Boeing 787 on June 12 resulted in nearly 300 casualties, sparking a debate on social media regarding the potential causes of the accident, which may involve both pilot error and mechanical failure [1][2][4]. Group 1: Potential Causes of the Crash - One theory suggests a rare dual-engine failure led to the loss of climb capability, supported by a distress signal from the pilots and reports of unusual noises during takeoff [1][2]. - Another theory points to human error during takeoff, as the aircraft did not retract its landing gear promptly, and the wing flaps appeared to be in an abnormal position [2][4]. Group 2: Stakeholder Reactions - The incident has led to a blame game between supporters of Boeing and those of the Indian airline, with accusations of racial bias and historical safety issues surrounding Boeing's aircraft [4][5]. - The crash has also implicated General Electric, the manufacturer of the engines, with some arguing that the responsibility lies with them rather than Boeing [7]. Group 3: International Implications - The incident has drawn in international commentary, with Turkish media clarifying that their companies were not involved in the maintenance of the crashed aircraft, which has been incorrectly associated with Turkey [11].
