System Description SKY497
Display
The display is a self-contained, 3-ATI -sized unit with a high resolution, green monochrome
Cathode Ray Tube ( CRT ) display. The bezel contains four momentary contact push-button
switches and an on/off/brightness knob. The display provides control and display
functions for the SKY497 and for a WX-1000 STORMSCOPE (if installed).
The display does not display traffic and storm information simultaneously. The position of
a remote SKYWATCH/STORMSCOPE mode switch determines whether the display dis-
plays traffic or storm information; however, if you’re in STORMSCOPE mode and the
SKY497 detects traffic that may pose an immediate threat to your aircraft, the display will
temporarily switch to SKYWATCH mode. Figure 1-2 shows the display with a typical
SKYWATCH screen. Figure 1-3 shows the display with a typical STORMSCOPE screen.

Interaction of Major Components
Figure 1-4 shows how the major components of the SKY497 connect to each other and to
other aircraft systems.
Notes on Figure 1-4:
1.The optional radio altitude input affects the SKY497 audio inhibit
feature, the ground target filtering feature, and the sensitivity levels
feature. (See chapter 3 for details.)
2.A flight data computer or other Arinc 429 output device may replace
individual analog sensors for supplying barometric altitude & heading.
3.The SKY497 will work without a heading input, but it will experience
degraded performance during high-rate-of-turn maneuvers.
4.The SKY497 may be installed on aircraft with fixed landing gear. The
optional landing gear position input affects the sensitivity levels feature.
(See chapter 3 for details.)
