B738的备用姿态仪由电瓶供电？
B738有几块电瓶，每个电瓶能独立供电30分钟吗？

第一个问题。The integrated standby flight display (ISFD) gets 28v dc from the ISFD dedicated battery/charger.
The ISFD dedicated battery system gets 28v dc from the battery bus. The battery/charger sends the 28v dc power to the ISFD. The battery/charger also uses the 28v dc power to charge its internal battery. A signal from the battery switch on the electrical meters, battery, and galley power module goes to the battery/charger. When the battery switch is on, the battery/charger supplies 28v dc power to the ISFD. When the battery switch is off, the ISFD does not receive 28v dc power.

第二个问题。
738只有一个电瓶。
With full charge, the battery gives a minimum of 30 minutes of standby AC and DC power.
