STANDBY BATTERY POWER SUPPLY
The G1000 installation incorporates a 24 vdc, 5 Ah JET model PS-835 Standby Battery
that provides electrical power for the standby attitude gyro, standby altimeter vibrator,
and internal lighting for the three standby instruments for a minimum of 30 minutes
following a total loss of aircraft power including the aircraft’s battery.
A push button switch located directly below the standby airspeed indicator controls the standby battery
power system. The switch is a push ON (switch latches in), push OFF (switch pops out) type of switch.
The system has three modes: OFF, ON, and ARM.
