致命1分钟，印度航空AI171为何起飞即失速

Core Viewpoint - The article discusses the tragic crash of Air India flight AI171, a Boeing 787, which occurred shortly after takeoff, raising questions about the causes of the incident and the unusual circumstances surrounding the flight [1]. Group 1: Flight Details - AI171 was a Boeing 787, known for its advanced avionics and flight control systems, and this incident marks the first crash of this aircraft model [3]. - Prior to the crash, the aircraft had completed a flight from New Delhi to Ahmedabad without reported issues, although passengers complained about onboard entertainment and climate control [3]. - The flight was scheduled to take approximately 9 hours to reach London after a brief stop in Ahmedabad for refueling and boarding [3]. Group 2: Takeoff Process - The takeoff process involved inputting load information into the aircraft's computer system, which is designed to provide necessary takeoff data, including flap configuration and decision speed [4]. - AI171 began its takeoff roll at 13:38 local time, reaching decision speed before lifting off [5]. - After takeoff, the aircraft failed to retract its landing gear and lost power shortly thereafter, resulting in a crash within a minute of takeoff [7]. Group 3: Emergency Response - After takeoff, the pilots declared a "Mayday," indicating a critical emergency situation, which typically requires the captain to take control of the aircraft [10]. - The time available for the pilots to respond to the emergency was extremely limited, with indications that the aircraft lost speed rapidly after becoming airborne [12]. Group 4: Potential Causes - The sudden loss of power could be attributed to various factors, including potential bird strikes or incorrect flap configurations, which may have affected the aircraft's lift [12][13]. - There are suspicions regarding human error, such as incorrect data input into the flight computer or failure to follow standard procedures during takeoff [13]. - The investigation is ongoing, with the flight data recorders being sought to uncover the reasons behind the crash [15].
