STANDBY ATTITUDE INDICATOR

A standby electric powered attitude indicator is located on the left portion of
the pilot-side instrument panel. In the event aircraft electrical power is lost,
the indicator will switch to an internal backup power source (rechargeable
sealed lead acid battery) to permit continued operation of the indicator. If
aircraft electrical power is lost, the attitude indicator will automatically operate
on battery power with the amber status LED flashing rapidly, indicating a
Power Loss Warning. With no further action from the pilot, the unit will turn
off automatically (Gyro Warning Flag in view) after approximately one minute.
This is to prevent battery discharge at the end of a flight when the master
power switch is placed in the off position.
When the instrument switches to Power Loss Warning, the amber LED
flashes for approximately one minute. This is intended to attract the pilot's
attention and indicate that there has been a loss of primary power to the
Attitude Indicator. Pushing the STBY PWR button on the face of the
instrument will allow the unit to continue operating on the standby battery until
battery power is exhausted. A full capacity standby battery will power the
instrument for approximately one (1) hour, depending upon conditions.
Any time aircraft power is absent, with the unit in either Power Loss Warning
or shut off, pushing the STBY PWR button will put the unit in standby
power mode. The unit will run on standby power until the standby battery is
exhausted. If the unit is running on the standby battery, pushing the STBY
PWR button again will restore standby power and standby lighting.
Restoring aircraft power will clear any standby operation and resume
automatic battery charging.
The control panel on the front of the instrument incorporates a manual
test feature. This test feature places the standby pack under load for
approximately one minute while displaying either a red or green light under
the word TEST on the front panel.
