Turn On the SKY497
To avoid power surges that could damage the SKY497 and the optional
WX-1000 , start your engines before turning on the SKY497 .
1. Turn the OFF/BRT knob clockwise to the desired display brightness.
The BFG oodrich screen (figure 2-2) appears and stays on the display until the power-
on self test is complete.
If the
SKY497 passes the test, and your aircraft has a squat switch, and your aircraft is
on the ground, the standby screen appears (figure 2-3).
If the
SKY497 passes the test, and your aircraft has a squat switch, and your aircraft is
in the air, the traffic screen appears set on the 6 nmi display range and the normal
altitude display mode (figure 2-4).
If the
SKY497 passes the test and your aircraft does not have a squat switch, the
standby screen appears (figure 2-3).
If a Failed screen similar to figure 2-5 appears, refer to the Failure Response section
on page 2-9. (For installations with an
ARINC 429 barometric altitude input, turning
on the
SKY497 during flight causes a temporary Error 20 message while the system is
syncing up to the
429 data source.)
Run the Operator-Initiated Self Test
You should run the operator-initiated self test before the first flight of the day or as specified
in your Aircraft Operating Manual (
AOM ).
1. With the SKY497 in standby, press the test button.
The SKY497 begins its self test and the test screen (figure 2-6) appears. Upon
successful completion of the self test, you will hear “Traffic Advisory System Test
Passed” and the display will revert to the standby screen.
