4.3.3 System Status
The Terrain system continually monitors several system-critical items, such
as database validity, hardware status, and GPS status. Should the system detect a
failure, a failure message will be displayed.
4.4 External H-TAWS
If an external 400W/500W-series H-TAWS unit is installed and interfaced to
the G500H, the alerts generated by the external unit will be displayed on the
PFD. Refer to the 400W/500W-series Garmin Optional Displays Pilot’s Guide
Addendum (p/n 190-00356-30) for more information regarding these alerts.
H-TAWS annunciations received from the GNS 400W/500W Series H-TAWS
unit will be displayed to the left and aligned with the top of the Altitude Tape on
the G500H PFD. A new annunciation will flash for approximately five seconds.
