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.
The HTAWS is an alerting system. The system does NOT guarantee
successful recovery from a conflict due to factors such as pilot response, aircraft
performance, and database limitations. No standardized recovery technique is
defined as recovery maneuvers may vary. The HTAWS shall NOT be used for
navigation purposes.
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.
• HTAWS annunciations can only be received from the #1 GNS unit if
multiple GNS units are installed.
• If the #1 GNS unit is powered OFF the G500H will revert to Terrain
HSVT alerting if equipped with synthetic vision.
• For External TAWS (HSDB), terrain impact points on the MFD are
generated from the data crossfilled from the GTN.
