2、飞行中，飞行机组成员突发不能履行其职责的，构成（ ）事件。

如果变压整流器组件1失效，直流通用汇流条会发生什么改变？If TRU 1 fails, what change occurs to DC UTIL BUS?

当所有的变压整流器组件在飞行中都不可用时，什么电源将向直流重要汇流条提供电源？What power source will supply electrical power to the DC ESS BUS when all TRUS are unavailable in flight?

如果变压器整流组件1和2不可用，什么将会向直流汇流条1和2供电？If TRU 1 and TRU2 are not available, what will power the DC BUS 1 and DC BUS 2?

当由于故障汇流条没有通电时，应急汇流条会显示在？Where is the EMER BUS displayed when the bus is unpowered due to a fault?
