Emergency Use

supply all airplane systems maintaining the SOURCE selector on BATT position.
In order to save battery power, it is possible to shed the charges that are not
essential for flight safety, for that set the ESS BUS TIE switch to EMER.
In this configuration, only ESS BUS 1, ESS BUS 2 and BATT BUS bars are
supplied.
NOTE
Supplying BUS 1, BUS 2, BUS 3 and BUS 4 bars is always possible, resetting
temporarily the ESS BUS TIE switch to NORM position.
