External TAWS

If a GNS 500WT-series or GTN-series with TAWS unit is interfaced as
GPS 1, text alerts generated by the external TAWS unit will be displayed on
the PFD. Refer to the GNS 500WT-series or GTN-series Pilot' s Guides and/
or Addendums for more information regarding these TAWS alerts. Text alerts
received from the GNS/GTN TAWS unit will be displayed to the left and aligned
with the top of the Altitude Tape on the PFD. A new annunciation will flash for
approximately five seconds.
• TAWS annunciations can only be received from the #1 GPS unit.
• If the Garmin GPS/TAWS is not available and Terrain-SVT is enabled, the
G500/G600 Terrain-SVT will generate PFD text alerts and aural callouts.
An advisory message will indicate when reversion to Terrain-SVT alerting
has occurred.
• For External TAWS (HSDB), terrain impact points on the MFD are
generated from the data crossfilled from the GTN.
