China Airlines Flight 605 (callsign "Dynasty 605") was a daily non-stop flight departing from Taipei at 6:30 a.m. and arriving at Kai Tak Airport in Hong Kong at 7:00 a.m. local time. On November 4, 1993, the plane crashed after overrunning the runway on landing during a storm.〔"(293 Rescued in Hong Kong After Jet Lands in the Water )." ''The New York Times''. November 4, 1993.〕 It was the first major loss of a Boeing 747-400. == Accident == Flight 605, a Boeing 747-400, touched down more than past the runway's displaced threshold, at a speed of , following an IGS runway 13 approach. Tropical Storm Ira was generating crosswinds on that runway, gusting to , from a heading of 070 degrees. 〔(AS Network )〕 The pilots received several computer-generated wind shear and glide slope deviation warnings, and observed severe airspeed fluctuations, during the last mile before touchdown. The auto brakes were set at only the number two level and then were turned off moments after touchdown, when the Captain elected to use manual braking and thrust reversal. The speedbrakes were extended momentarily, but then retracted. This caused the plane to "float," making the brakes ineffective until the speed brakes were extended again. The Captain deliberately turned the plane to the left when he realized the plane would go off the end of the runway, and into the approach lighting system (ALS) for runway 31. That action caused a "ground loop", making the plane slide off the left side of the runway into Victoria Harbour, thereby preventing a collision with the ALS for runway 31. It finally came to rest in shallow water, with a heading of almost 180 degrees out from the direction of runway 13. A British Airways pilot had refused to make the approach to Kai Tak runway 13 minutes before the CAL 605 Captain decided to attempt it. The investigation indicated that the accident was caused by the Captain's failure to initiate the mandatory missed approach procedure when he observed the severe airspeed fluctuations, combined with the wind shear and glide slope deviation alerts. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「China Airlines Flight 605」の詳細全文を読む スポンサード リンク
