annunciations are supported:
Refer to the Garmin G1000 CRG Appendix A for more information on
system annunciations.
MASTER SWITCH
The MASTER switch is a two-pole, rocker-type switch. The BAT side of
the switch controls the main battery electrical power to the airplane.
The ALT side of the switch controls the alternator system.
In normal operation, both sides of the switch (ALT and BAT) are ON
simultaneously; however, the BAT side of the switch may be selected
separately as necessary. The ALT side of the switch can not be set to
ON without the BAT side of the switch also being set to ON.
If the alternator system fails, the MASTER switch may be set in the
OFF position to preserve main battery capacity for later in the flight.
With the MASTER switch OFF and the STBY BATT switch in the ARM
position, the standby battery will power the essential bus for a limited
time. Time remaining may be estimated by monitoring essential bus
voltage. At 20 Volts, the standby battery has little or no capacity
remaining.
