Inhibit Mode
The Garmin TERRAIN system provides an ‘inhibit
mode’. This mode is designed to deactivate terrain
alerting when deemed unnecessary by the pilot. Flying
VFR into an area where unique terrain exists could cause
the system to annunciate nuisance alerts. Pilots should
use discretion when inhibiting the TERRAIN system and
always remember to enable the system when appropriate.
See Section 11.3 for more information on TERRAIN
alerts.
To inhibit TERRAIN:
1) Select the TERRAIN Page and press the MENU
Ke
