However, the captain failed to use any rudder inputs at all, before or after disconnecting the autopilot. To counteract the asymmetrical forces created by the loss of thrust from the No. 4 engine, it was essential for the pilot to manually use the left floor pedal to push the rudder to the left. Ailerons and flight spoilers were the only means available to the autopilot to keep the wings level as the autopilot does not connect to the rudder during normal flight. By the time the captain disconnected the autopilot the aircraft had rolled over 60 degrees to the right and the nose had begun to drop. As the speed decreased even further the aircraft began to roll to the right even though the autopilot was maintaining the maximum left roll limit. Meanwhile, as the airspeed decreased, the autopilot rolled the control wheel to the maximum left limit of 23 degrees while maintaining level flight. According to the flight manual, engine restart is unlikely to succeed above 30,000 feet (9,100 m). : 26 After the flight engineer announced the engine had flamed out, the captain instructed him to restart it and ordered the first officer to request clearance for a descent from 41,000 feet (12,500 m). The flight engineer attempted to restore power to the engine but did not close the bleed valve as required by the checklist procedure. Aircraft roll and pitch attitudes and time None of those acts fixed the recurrent problem with the No. 4 engine. The maintenance response to the logbook entries that noted the attempted solutions included engine inspection fuel filter drainage and replacement vane controller inspection and replacement water drainage from Mach probes and other filter replacements. In each of those cases the engine was restarted after descending to a lower altitude. That engine had failed twice during previous flights (while cruising at FL 410 and 430). The sequence began with a loss of thrust in the No. 4 engine. The accident occurred while the main crew was on duty. The first officer had more than 7,700 hours with 4,553 of them on the Boeing 747, and the flight engineer had approximately 15,500 hours of flight time, including 4,363 hours on the Boeing 747. The captain had approximately 15,500 flight hours, including 3,748 hours on the Boeing 747. The cockpit crew consisted of Captain Min-Yuan Ho, age 55 First Officer Ju-Yue Chang, age 53 Flight Engineer Kuo-Pin Wei, age 55 Relief Captain Chien-Yuan Liao, age 53 and Relief Flight Engineer Shih-Lung Su, age 41. The Boeing 747SP-09 was 350 miles (560 km) northwest of San Francisco, cruising at an altitude of 41,000 ft (12,500 m). The accident occurred 10 hours into the flight. The aircraft had departed from Taipei at 16:22 China Standard Time. Accident N4522V, the aircraft involved, seen at Kai Tak Airport in 1991 The plane rolled over and plunged 30,000 ft (9,100 m), experiencing high speeds and g-forces (as high as 5g ) before the captain was able to recover from the dive, and then to divert to San Francisco International Airport. On February 19, 1985, the Boeing 747SP operating the flight was involved in an aircraft upset accident, following the failure of the No. Pacific Ocean, near San Francisco, California, United StatesĬhina Airlines Flight 006 ( call sign "Dynasty 006") was a daily non-stop flight from Taipei to Los Angeles International Airport. High-altitude upset and 30,000 ft dive due to spatial disorientation after failure of Engine 4 caused by Pilot Error, and Pilot fatigue Every function that this aircraft has, has either a button, switch or lever to operate it, together with all the gauges you need.Damage to N4522V's horizontal stabilizers after it experienced an uncontrolled descent of 30,000 ft You can operate everything from the cockpit. It also has an APU, which doesn't really do anything, but it does make sound and there's a button for it in the cockpit! It has realistic internal and external lighting, animated thrust reversers, animated FLAPS and SLATS, realistic speed brakes, animated landing gear and last but not least, a fully functional cockpit which should be VR capable once Simpleplanes VR comes out. Most importantly about this aircraft though, is that everything works! Kinda looks like a 787 and A350 combined from the outside and it has an Airbus-ish cockpit. Yeah, I know, name creativity is out of the windows at the moment.Īnyway, it's a bit of everything combined.
