A330 battery check
Hi all,
Please go easy on me ! I have some questions regarding the battery check during A330 preliminary cockpit preparation.
1. When we check the battery above 25.5 V, after the check, the selector should remain on APU position to minimize discharge of BAT 1 and 2. What exactly does this mean? How does BAT 1 or 2 get discharged?
2. For the APU start, if one of the batteries is lower than 23.5V, there is a risk of aborted APU start. In my understanding, APU has its own dedicated battery in order to start. Why do BAT 1 or 2 voltages have effect on APU start?
thank you,
