If there is an electrical demand above what can be produced by either
alternator, the corresponding battery temporarily satisfies the increased
requirement and a battery discharging condition exists. As the battery
charge is expended, the voltage to the system will read something less
than the optimum 24 volts. At approximately 8 volts, most electrical
components on the affected bus will cease to work or will operate
erratically and unreliably. The minimum voltage for proper operation
of the Garmin G900X is 9 volts. Anytime the electrical demand is
greater than what can be supplied by the alternator at any RPM on any
bus, the battery is in a discharging state. The PFD annunciation
window will display “
L Alt Off
” or “
R Alt Off
” when that bus drops
below 24 volts. The alternator will continue to output as much as it can
for the RPM the engine is producing. Reducing loads or increasing
RPM should clear the “
L Alt Off
” or “
R Alt Off
” annunciation message
and the battery will be in a charging state. If the discharging state is
not corrected there will be decay in the voltage available to the
electrical system of the airplane and systems will cease to operate.
In the event of total electrical system failure, the backup attitude
indicator will continue to operate on an internal battery supply for up to
one hour. The following is a checklist to activate the attitude
indicator’s standby battery:
AI Amber Light
ILLUMINATED AND
FLASHING
STBY PWR Button
PRESS ONE TIME
GYRO WARNING
FLAG
OUT OF VIEW
NOTE
If the STBY PWR was not pressed during the one-
minute warning mode but internal battery
operation is required – press the STBY PWR one
time to turn the indicator on.
ELECTRIC TRIM / AUTOPILOT FAILURE
Flight
MANUALLY CONTROL THE
AIRCRAFT
Autopilot DISCONNECT
using control stick button
Circuit Breakers
PULL as required
Power
REDUCE to 50% or less (or to a setting
that relieves control forces)
SpeedBrakes
DEPLOY as required to reduce speed to
relieve control forces
Airspeed
REDUCE to relieve control forces
