The captain and co pilot of BA038 on duty are Peter Bergier and John Coward, both of whom have over 6000 hours of flight experience and have flown this London Beijing route more than ten times. They are very familiar with this route, and there is also an unknown second co pilot. They praise the highly automated operation and fully glass instrument operation experience of the Boeing 777, which has flown over two million times in the past decade since its inception, with a very beautiful and perfect flight record. For the crew of long-distance flights, most of the time they actually don't need to do anything at all. The autopilot will fly autonomously under the control of the automatic throttle based on the pre-set waypoint. The crew spends most of the time in the cockpit watching the scenery, and only needs to manually operate during takeoff and landing. The automatic terminal information service system of the aircraft (an automatic broadcasting system that continuously broadcasts meteorological information, available runway information, available approach procedures, and other basic information required for crew approach in a busy airport airspace, greatly reducing the working pressure of air traffic control) broadcasts the actual climate and temperature of London Heathrow Airport to the crew and advises them to approach the 27L runway. During the approach, the aircraft encountered a strong wind with a wind speed of 20-30 knots, causing it to shake violently. However, for the Boeing 777 with automatic throttle control, the impact is not worth mentioning and it can be completely handled without the need for crew intervention. The captain pushed the throttle to TOGA, but there was still no sign of acceleration on the engine gauge. The speed on the gauge was still decreasing, indicating that the two Rolls Royce Trent 895 turbofan engines of the aircraft were losing power. In this case, the aircraft would crash in more than ten seconds, and the crew and passengers in th
