5. Initiate the intruder scenario and verify a target is annunciated on the MAP-TRAFFIC
MAP page of the MFD at the correct bearing of approximately 0-degree azimuth at 2 NM
(read as +05 above a filled diamond indicating proximate traffic).
6. On the ramp tester, toggle intruder traffic to standby or off.
7. Reposition ramp tester and reengage the same intruder scenario for 90, 180 and 270
degrees relative to the aircraft.
8. Verify a target is annunciated on the MAP-TRAFFIC MAP page of the MFD at the same
bearing as the ramp tester.
9. If the bearing is not as anticipated or multiple targets are displayed during tests (not
including possible local targets), verify the following:
•
Coax cable connectors are properly secured at the bulkhead adapter fittings, GA
58 antennas, and GTS unit.
•
Connections are made to the proper channels and color-coded heat shrink is the
same color on both ends of coax cables.
•
Connectors are correctly installed on coax cables.
System Test
The following test provides a scenario that will converge and intercept the GTS to assure proper
operational and surveillance functions.
Prior to simulating the 'in-air' condition, please contact your local Air Traffic
Control (Center and Approach) and inform them of your intention to perform
aircraft testing that may transmit ADS-B Out signals of an aircraft in the 'in-air'
condition. Closed hangar doors may not provide adequate isolation from ATC.
Disconnect the radar altimeter receive coaxial cable or cover the receive antenna so the
radar altimeter reads over 2000 feet.
For GTS 8000 TCAS II test only, perform the following:
a. Change BARO setting to 29.92 in-Hg on PFD1 and PFD2.
b. Set the main landing gear WOW actuators in the air position.
On the MAP-TRAFFIC MAP page of the MFD, perform the following:
a. Press the OPERATE softkey (for TAS/TCAS I) or TA/RA softkey (for TCAS II).
b. If an "ADS-B" softkey is displayed, press the softkey to turn it off.
Position ramp tester at 90 degrees (i.e. off the right wing).
Select the following on the ramp tester:
•
Intruder type: ATCRBS.
•
Intruder Start Distance: 10 nm
•
Intruder Start Altitude: 300 ft above PFD1 displayed altitude
•
Vertical Speed: 0 fpm
•
Velocity: 360 kts
