Many thanks. From that, ANA Main Battery had a spontaneous failure? It must meet basic charge level to launch, so would not be charged after T/O, right?
Is the only start voltage available for APU the APUBATT? It seems unusual to require a backup battery to Start the APU in normal ops. Because if an airborne start, the APU BATT might go below legal level, and be unable to start the APU in an actual abnormal?
Not for use during Flight?
