GTS 855 - “TCAS I system Passed” or “TCAS I system Failed”

GTS 8000 - "TCAS II system Passed" or "TCAS II system Failed"

Any faults and flags are also displayed on the Normal Tab of the GTS Processor Install Tool. Faults that

occur will be colored in red and flags will be colored in black.

If self test fails, refer to the diagnostics data to determine a cause.

Ensure that no Intruder appears at close range to own aircraft.

If the intruder appears at close range to own aircraft, verify that the mutual

suppression line is connected between GTS Processor and other L-band

equipment (transponder, DME, etc.).

3.9.6 Ramp Test and Return To Service Test

For helicopter installations with the traffic system status valid discrete output

wired to the air/ground discrete input, the ground test must be performed with the

squat 'on-ground' sense temporarily configured as 'ground'. After performing the

ground test, reconfigure the squat 'on-ground' sense to 'open'.

Garmin Integrated Flight Deck HSDB installations with GDU software versions

prior to 11.10 require the USB interface dongle cable (Appendix B) to allow use

of the GTS Processor Install Tool to simulate flight conditions such as altitude of

50,000 feet, gear up, etc (Section 3.8.2). Garmin Integrated Flight Deck HSDB

installations with GDU software versions 11.10 and newer can access the Ground

Test from the MFD to perform these tests. Consult Garmin for details.

For Garmin Integrated Flightdeck HSDB installations with GDU Software Versions prior to 11.10:

Activate ground test mode by clicking ‘Enable’ in the Ground Test field on the Normal Tab of the GTS

Processor Install Tool.

Figure 3-17 Ground Test Enable, GTS Processor Install Tool

For Garmin Integrated Flightdeck HSDB installations with GDU Software Versions 11.10 and

newer:

The Ground Test command is accessed from the MFD in normal mode while the aircraft is on the ground

by pressing the softkey sequence 3, 4, 4, 3. After pressing the softkeys in sequence, a 'GND TEST' softkey

appears, to allow the user to activate/deactivate the Ground Test. Press the 'GND TEST' softkey to begin

the procedure.
