Chapter 1 – System Description

 SKY497 Pilot’s Guide

1-4

Interaction of Major Components

If you’re using only an alternate display, you will also have a
customer-supplied on/off switch for the 

SKY497

 and discrete

buttons for range, vertical display mode, operate/standby, and
test if the alternate display can not provide these functions.

Some alternate displays have the same display ranges as the 

WX-

1000/SKY497

 display while others generate their own display

ranges. The 

RGC

/radar indicator displays 

SKY497

 traffic in 

2

and 

6

 nmi display ranges only.

Hereafter, the word 

display

 generally refers to the 

WX-1000/

SKY497

 display unless otherwise indicated. For any other

displays, refer to that display’s manual for a description of how
it displays 

SKY497

 traffic information.

Interaction of Major Components

Figure 

1-5

 shows how the major components of the 

SKY497

connect to each other and to other aircraft systems.

Notes on Figure 1-5:

1. The optional radio altitude input affects the 

SKY497

 audio

inhibit feature, the ground intruder filtering feature, and the
sensitivity levels feature. (See chapter 

4

 for details.)

2. A flight data computer or other 

ARINC 429

 output device

may replace individual analog sensors for supplying baromet-
ric altitude and/or heading.

3. The 

SKY497

 works 

without

 a heading input, but experiences

degraded performance during high-rate-of-turn maneuvers.

4. Having a weight-on-wheels input allows the 

SKY497

 to

automatically switch out of standby when you take off, and
into standby when you land.

5. The 

SKY497

 may be installed on aircraft with fixed landing

gear. The optional landing gear position input affects the
sensitivity levels feature and the 

SKY497

 audio inhibiting

feature. (See chapter 

4

 for details.)

6. The control panel consists of only a power switch if you’re

using only the 

RGC

/radar indicator. The size, scale, scope,

and implementation of the control panel depends on the type
and number of displays installed.
