Operating Instructions SKY497
Switch Between SKYWATCH and STORMSCOPE Modes (Optional)
If you have a STORMSCOPE WX-1000 installed with the SKY497 , you can switch between
SKYWATCH and STORMSCOPE screens (figures 1-2 and 1-3) using the remote SKY-
WATCH/STORMSCOPE
mode switch. Once in STORMSCOPE mode, you can use the
buttons on the display bezel to control STORMSCOPE functions.
If the SKY497 is in SKYWATCH mode, the display will not
automatically switch into STORMSCOPE mode to display thun-
derstorms or STORMSCOPE errors: You must use the remote
SKYWATCH/STORMSCOPE mode switch to periodically check
for thunderstorms or STORMSCOPE errors.
The SKY497 does not superimpose SKYWATCH data on top of STORMSCOPE data or vice
versa; however, if the SKY497 is in STORMSCOPE mode and the SKY497 detects a TA , the
display automatically switches back to SKYWATCH mode until the TA goes away. Also, if
the SKY497 is in STORMSCOPE mode and the SKY497 detects a failure, the SKY497 Failed
screen appears with a message to “Press Any Key to Ack.” Pressing any key switches the
SKY497 back to STORMSCOPE mode.
Observe the Display
The SKY497 relies on information obtained from transponders
in nearby aircraft. The SKY497 does not detect or track aircraft
which are not equipped with an operating ATCRBS transponder.
The SKY497 does not track intruder aircraft approaching at a
closure rate greater than 900 knots.
Some traffic within the chosen display range may not be displayed
due to traffic prioritizing or antenna shielding.
Optimum SKY497 performance is realized when intruder aircraft
are reporting their altitude (via a mode C or other altitude
reporting transponder).
