SKY899 Pilot’s Guide
3-2
Preliminary
If the SKY899 passes the test and your aircraft does not have a
squat switch, the standby screen (figure
3-2) appears.
In standby, the
SKY899 waits 5 minutes for critical sensors such
as the barometric altimeter to warm up and come on line
before it displays a
Failed screen or
MSG
due to the lack of the
sensor input; however, if you switch into operating mode, the
SKY899 only waits 2 seconds for the sensor inputs before it
displays the Failed screen or
MSG
.
If a
Failed screen similar
to figure
3-4 appears, or if
you see
MSG
, refer to the
Message Response section
on page
3-7. For installa-
tions with an
ARINC 429
barometric altitude input,
turning on the
SKY899
during flight causes a
temporary
Error 20
message while the system
is syncing up to the
429
data source.
