下面是他们在印尼空难之后发的警告通知,在自动驾驶误读攻角数据后如何人工改正。太轻描淡写了吧!按上面所说(红色部分)如果继续失控就要不停地强制手动控制俯仰操纵面,天哪,这是要飞行员用人力和自动驾驶掰腕子啊!虽然有电子助力,这种反复翻转操纵面的行为几乎必然会让飞机持续减速,进一步加剧自动驾驶强制低头的努力,结果就可能把操纵面飞掉,直接撞地!6parker.com

这简直就是程序性谋杀啊!6parker.com

The FAA has issued an Emergency Airworthiness Directive …6parker.com

6parker.com

"This emergency AD was prompted by analysis performed by the manufacturer showing that if an erroneously high single angle of attack (AOA) sensor input is received by the flight control system, there is a potential for repeated nose-down trim commands of the horizontal stabilizer. This condition, if not addressed, could cause the flight crew to have difficulty controlling the airplane, and lead to excessive nose-down attitude, significant altitude loss, and possible impact with terrain. 6parker.com

Runaway Stabilizer:6parker.com

Disengage autopilot and control airplane pitch attitude with control column and main electric trim as required. If relaxing the column causes the trim to move, set stabilizer trim switches to CUTOUT. If runaway continues, hold the stabilizer trim wheel against rotation and trim the airplane manually.
