ARINC 429 Traffic System Interface Check

If a Garmin GTS 8XX Traffic system, L3 Communications SKY497/SKY899 SkyWatch sensor or a
Honeywell (Bendix/King) KTA 810 TAS/KMH 820 IHAS has been connected to the GTN via ARINC
429, the traffic interface should be verified as described in this section.
1. With the GTN running in the normal mode, go to the Traffic page by touching the 'Traffic' key on
the Home page.
2. Verify that NO DATA is not displayed in yellow on the center of the traffic page.
3. Verify that the traffic system mode can be changed from STBY to OPER.
4. Switch the traffic system mode to STBY, and then run the traffic self test from the Menu.
5. Verify that the traffic system executes a self test and a self-test pattern is displayed on the GTN
traffic display.
6. Restart the GTN in configuration mode.
7. Access the Traffic page from the External Systems page and verify that there is data displayed in
the altitude field.
6.12.5 Stormscope
If an L3 Communications WX-500 Stormscope has been connected to the GTN, the Stormscope interface
should be verified as described in this section.
1. With the GTN running in the normal mode, go to the Weather page by touching the 'Weather' key
on the Home page.
2. Touch the 'Stormscope' key.
3. Verify that LIGHTNING FAILED is not displayed in yellow on the center of the page.

GMX 200/MX20 Interface Check

If a Garmin GMX 200 or MX20 has been connected to the GTN, the interface should be verified as
described in this section.
1. With the GTN running in the normal mode, ensure that the GTN has a valid GPS position.
2. Create and activate a flight plan on the GTN.
3. Verify that the RTE and POS data flags are not displayed on the GMX 200/MX20.
4. Verify that the flight plan is displayed on the GMX 200/MX20 using the flight plan (FPL) func-
tion.

GDL 69/69A Interface Check

If a Garmin GDL 69 has been connected to the GTN, the interface should be verified as described in
Section 6.12.7.1. If a Garmin GDL 69A has been connected to the GTN, the interface should be verified as
described Sections 6.12.7.1 and 6.12.7.2. Each of these procedures involves verifying that the satellite
signal is acquired and tracked. Locate the aircraft where there is a clear view of the southeastern or
southwestern sky. XM Satellite Radio satellites are located above the equator over the eastern and western
coasts of the continental United States.
NOTE
The following sections only verify the correct interface of GDL 69/69A to the GTN. It does
not activate the GDL 69 XM data link radio. Complete instructions for activating the XM
data link radio can be found in document 190-00355-04, GDL 69/69A XM Satellite Radio
Activation Instructions.
