Note: The antenna position setting and stabilization source must agree with the WX-500 jumper
setting and the physical mounting location of the antenna.
4. For the TWX670 the following options are available in the TWX670 Config page:
■ Enable geo stabilization – an external position source (GPS or FMS) connected to the sensor
will stabilize the lightning strikes to the aircraft position
■ Enable heading stabilization – an external heading source (e.g., a synchro) connected to the
sensor will stabilize the lightning strikes to the aircraft heading.
■ Enable Audio Output – if connected to the aircraft audio panel, the TWX670 will provide
audible warnings concerning nearby lightning strikes.
These options are only available after the Sensor and Port options have been selected and
the MFD restarted. Green check marks will appear next to each option if the TWX670 agrees
with the configuration. If red X’s appear, it may be because another display connected to the
sensor is trying to set a different configuration. Consult the TWX670 installation manual for
more information.
5. When you are done, press Save. Press Cancel to exit without saving changes.
6. Changes do not take effect until the MFD has been restarted. From the Maintenance Mode Page,
press Restart System.
In addition to the settings on the Lightning Setup Page, the following buttons may be available:
● WX-500/TWX670 Diags – allows access to the lightning sensor diagnostic modes. See your
sensor’s Installation Manual about how to verify software versions, wiring configurations, antenna
environment, and fault logs (not available on all software releases).
● Self Test (WX-500) – Runs the WX-500 Self Test and reports Pass or Fail. See the WX-500
Installation Manual for information about testing and the interpretation of the results (not available
on all software releases).
