6.12.15 TIS (Garmin GTX 33/330) Interface Test
If a Garmin GTX 33/330 sensor has been connected to the GTN, the traffic interface should be verified as
described in this section.
1. Select the Traffic Map on the GTN.
2. Verify that TIS FAIL is not displayed in the upper left corner under Traffic Status, and that NO
DATA (yellow) is not displayed over the ownship symbol.
3. On the upper left corner of the Traffic Map page, verify that the status of the traffic system is either
TIS Standby or TIS Operating/Unavailable (i.e. TAS should not be displayed).
The following additional steps should only be completed if the GTN is controlling the traffic system.
1. Pull the transponder circuit breaker and verify the air data fields are red ‘X’d.
2. If a squat switch (or airspeed switch) is connected to the GTX 33/330, ensure that it is in AIR
mode.
3. Alternately touch the ‘Standby’ key and ‘Operate’ key to change the mode of the traffic system. It
may take several seconds for the traffic system to change modes.
4. Verify that the mode of the traffic system can be changed.
6.12.16 Transponder Interface Check
If the GTN is interfaced to a GTX 32/33 remote transponder or a GTX 327/328/330 configured as a remote
transponder, the following checks must be completed.
1. With the GTN unit running in normal mode and the transponder powered on, go to the Home page
and ensure there is no red ‘X’ over the transponder data field on the top right of the screen.
2. Ensure that a code can be entered into the code field. Enter a code using the keypad and then touch
‘Enter’. Ensure the code that was entered is displayed in the transponder data field.
3. If dual transponders are installed, select transponder 2 and perform steps 1 and 2 for the second
transponder as well. Also pull the transponder 1 circuit breaker and ensure the transponder 1 data
field is red ‘X’d rather than the transponder 2 data field to verify that the wiring is not crossed. (i.e.
transponder 1 is incorrectly connected to transponder 2 circuit breaker.)
4. Repeat the preceding steps for the second GTN.
