3.8.3 TAS/TCAS Antenna Calibration
This calibration is available only if the Lynx NGT-9000 with TAS/TCAS option is installed and the
TAS/TCAS option is selected in the aircraft specific options. If information is showing in the Calibration
angle and LRU S/N fields then the calibration has already been accomplished.
1. From the MPC (MAT) select Setup > Calibration.
2. Press the Initiate button within the TAS/TCAS Antenna Calibration box to activate the "TAS/TCAS
Antenna Calibration" status dialog window.
• A dialog window is shown stating, "The request succeeded and the calibration will be
performed on the next boot of operational software".
3. Restart the unit by selecting Service > Restart Unit Mode in Operational Software Mode.
4. When the unit is calibrating in normal operation the message "Calibrating Antenna" is shown on the
traffic application screen (right side).
• If the calibration passes, the LRU serial number (obtained from the factory configuration) and
calibration angle is written into the configuration module for subsequent use.
• If calibration fails, then the message "Calibration Failed" is shown on the traffic application
screen for a short duration. The system continues to try to calibrate the antenna once each boot
until it is successful.
Refer to the troubleshooting information in the maintenance section if the TAS/TCAS continues
to fail. A TAS or TCAS fail will also be shown on the message screen. The MSG button does
not appear on the screen until after 2 minutes of the unit being in normal operation.
3.8.4 Ambient Light Sensor
Use this function to adjust how the ambient light sensor dims or brightens the NGT-9000 display.
1. From the MPC (MAT) select Setup > Calibration.
2. Set the Ambient Light Sensor Range from 1 to 5 and press the Apply button. The higher the range
the greater the brightness in the lowest ambient cockpit light. Note - Does not affect maximum
brightness in full sunlight.
3.8.5 Viewing and Downloading Fault Log
If an anomaly occurs, viewing of the fault log can distinguish between an external equipment problem
(i.e. input to the NGT-9000) or a NGT-9000 internal problem.
To view the fault log, in maintenance mode, select Info -> Fault Log. By clicking on a given fault, a
Fault Description and Loss of Functionality indication is made in the upper panel of this screen as seen in
Figure 3-15.
In some cases, the file may be returned to ACSS for evaluation by performing a fault download. In order
to download the fault log, perform the following steps.
1. In maintenance mode, select Info > Fault Log. See Figure 3-15.
2. Select the Save button at the bottom of this screen.
3. Name the file with a tail number or other identifying name. This log is written to the location chosen
as a generic file (no extension needed).
4. This file can then be provided to ACSS for evaluation.
