3.11.1.7 Discrete Switch Checks
Verify the following external switches are functioning properly (if installed). Note: The MPC can be used
to validate the inputs for the external checks. See paragraph 3.9 for details.
1. If installed verify that the Audio Mute feature inhibits audio messages sent by the unit. This is
connected to a CAWS alerting system.
2. If installed verify that the Standby Mode input switch places the unit’s transponder into Standby
Mode.
The Panel Mount NGT-9000 Transponder screen indicator displays “STANDBY”.
The Remote Mount NGT-9000R with a CP-2500 will display “STANDBY” for Release 2.1 or
later.
3. Verify that the IDENT Input switch causes the unit transponder to transmit the "ident" flag in
transponder interrogation replies. This check may be skipped if verified during the configuration
setup procedure.
4. The On-Ground switch function is verified by the operation of the System Test button (panel mount
version only) and is available on the Transponder Application screen and the ON-GND message
located on the transponder screen.
5. The Audio Acknowledge switch cancels the audio from a TAWS or Traffic Aural. This check may
be skipped if verified during the configuration setup procedure.
3.11.1.8 Alternate Display Check
The Lynx NGT-9000 may be interfaced to a compatible traffic display (ARINC 429 or RS-422) and
weather display (RS-422). The instructions provided in this manual are generic. Refer to the
manufacturers display manual for operation and checkout procedures.
A functional check with the Lynx NGT-9000 is accomplished during the check of the ADS-B In,
TIS-B, FIS-B, and any other checks requiring the use of the alternate display.
3.11.1.9 CP-2500 Control Panel Check
The checkout of the CP-2500 Control Panel is accomplished using the instructions found in the CP-2500
Installation Manual. Refer to the References information in the front section for details.
3.11.2 Ground Checks
Perform only those checks that are applicable to the installation. An IFR-6000 (or equivalent) Ramp Test
Set is required.
NOTES
1. These checks assume familiarity with the set up and operation of
the ramp test set.
2. All test equipment used in completing these tests shall be
calibrated in accordance with the manufacturer’s
recommendations.
