Обороты левого двигателя уменьшаются, крен, курс начал меняться влево. После всего команда диспетчера набирать высоту и квитанция экипажа. Дальше при крене больше 45* отключился АП, следом АТ. Где были педали, очень скупой отчет.
И почему не убавить обороты правого чтобы уменьшить разнотяг, тоже не понятно.
Почему курс начал меняться это мы теперь знаем, а они вряд-ли. 38.42 - начало развитие ситуации, 38.51 - запрос на смену курса, 39.01 - ограничение по высоте для расхождение с другим
бортом, 40.05 - отключение ап. Итого менее минуты чтобы понять почему самолёт с включенным ап едет не туда. А после отключения ап элероны в нейтраль же уходят? Если да, то это ещё больше усилит рост крена сразу после отключения ап. Получаем положение вверх колесами, в облаках и с большим разнотягом, причем внезапно для экипажа.
At 14:38:42 LT, the FDR data recorded that as the aircraft climbed past 8,150 feet,
the thrust lever of the left engine started reducing, while the thrust lever position of
the right engine remained. The FDR data also recorded the left engine N14 was
decreasing whereas the right engine N1 remained.
At 14:38:51 LT, the SJY182 pilot requested to the TE controller for a heading
change to 075 to avoid weather conditions and the TE controller approved the
request.
At 14:39:01 LT, the TE controller instructed SJY182 pilot to stop their climb at
11,000 feet to avoid conflict with another aircraft with the same destination that was
departing from Runway 25L. The instruction was read back by the SJY182 pilot.
At 14:39:47 LT, the FDR data recorded the aircraft’s altitude was about 10,600 feet
with a heading of 046 and continuously decreasing (i.e., the aircraft was turning to
the left). The thrust lever of the left engine continued decreasing. The thrust lever of
the right engine remained.
At 14:39:54 LT, the TE controller instructed SJY182 to climb to an altitude of
13,000 feet, and the instruction was read back by an SJY182 pilot at 14:39:59 LT.
This was the last known recorded radio transmission by the flight.
At 14:40:05 LT, the FDR data recorded the aircraft altitude was about 10,900 feet,
which was the highest altitude recorded in the FDR before the aircraft started its
descent. The AP system then disengaged at that point with a heading of 016, the
pitch angle was about 4.5° nose up, and the aircraft rolled to the left to more than
45°. The thrust lever position of the left engine continued decreasing while the right
engine thrust lever remained.
