5.5.6 Traffic System Interface Test
The GMX 200 can provide mode control and display data from various traffic systems. This check
verifies that the GMX 200 is configured correctly and is receiving and transmitting data to the traffic
system.
NOTE
If the GDL 90 is being used as the traffic system, refer to section 5.5.10.
5.5.6.1 ARINC 429 Traffic Interface Test
If an L3 Communications SKY497 / SKY899 SkyWatch® sensor or a Honeywell (Bendix/King) KTA
810 TAS / KMH 820 IHAS has been connected to the GMX 200 I/O, the traffic interface should be
verified as described in this section.
1.
Verify that the amber TRAF flag is not displayed.
2.
Select the Traffic (TRAF) function on the GMX 200.
3.
On the lower right hand corner of the traffic function page (above the Vert: display), verify that the
status of the traffic system is either TAS Standby or blank (i.e. no status should be presented).
NOTE
If the GMX 200 is configured for TAS+Disp (i.e. a display other than the GMX 200 is
controlling the traffic system), then the following steps do not have to be carried out.
4.
Press the
MENU/ENT
key and press the STANDBY/OPERATE line select key to change the mode
of the traffic system. It may take several seconds for the traffic system to change modes.
NOTE
The Self Test key will not appear if the traffic system is operating. If the mode was
changed from Operate to Standby, the
MENU/ENT
key will have to be pressed twice to
refresh the line select key menu.
5.
Put the traffic system in Standby mode. Press the Self Test line select key to initiate a traffic system
self test. Verify that the traffic system runs a self-test and the self-test traffic pattern is displayed.
6.
Using the Message function, verify that no error messages have been posted from the traffic system.
