5.3.20 TRAFFIC Page
The following pages are only available if one of the RS-232 inputs is configured for the
Ryan TCAD or one of the ARINC 429 inputs is configured for Traffic Advisory.
Select the TRAFFIC Page (see Figure 5-24). This page
shows the L3 Communications SkyWatch or Ryan TCAD
modes of operation and current traffic situation.
For L3 Communications SkyWatch, this page shows:
1. The altitude mode—below (BLW), normal
(NORM), above (ABV), or unrestricted (UNR)
2. The operating mode—standby (STBY) or
operating (OPER)
3. Current altitude (ALT)
4. Altitude limits being imposed (LIM A and LIM B)
5. Heading, and barometric (BARO) and radio (RAD) altitude status.
For L3 Communications SkyWatch (see Figure 5-24), verify that the 400W Series unit can change the
SkyWatch operating mode (STBY or OPER). In standby mode, verify that the SkyWatch may be placed
in self-test mode by highlighting "Test Mode?" and pressing ENTER on the 400W Series unit. Refer to
the L3 Communications SkyWatch installation manual for system checkout.
For Ryan TCAD (see Figure 5-25), this page shows the
current shield mode and altitude. Verify that the TCAD
shield mode may be changed—Ground (GND), Terminal
(TML), Standard (STD), En Route (ENR), or Unrestricted
(UNR), and that the TCAD is reporting the correct altitude.
Refer to the Ryan TCAD installation manual for system
checkout.
