ISSUED: JULY 12, 1995 REPORT: VB-1611
REVISED: SEPTEMBER 12, 2005 3 of 4, 9-141
SECTION 4 - NORMAL PROCEDURES
Preflight Check
1. Apply aircraft power and allow the gyro to spin up for approximately 2
minutes.
2. Press and hold the STBY PWR button.
3. Verify that after several seconds the amber LED has started to flash. This
indicates that the unit has latched into the Battery Test Mode. At this time
the STBY PWR button can be released.
4. Verify that a green annunciator is illuminated under the word TEST.
5. Visually monitor the test lights until the amber LED stops flashing,
signaling the end of the test.
NOTE
A green annunciator throughout the test indicates the
standby battery is sufficiently charged and should be able to
function under normal operation. The presence of a red
annunciator at any time during the test is an indication the
standby battery is in need of charging, or possibly
replacement.
NOTE
The Standby Attitude Indicator will operate for approximately
one hour with the internal battery, depending on battery
condition at the time of power failure.
SECTION 5 - PERFORMANCE
No change.
SECTION 6 - WEIGHT AND BALANCE
Factory installed optional equipment is included in the licensed weight and
