Inhibit Mode

The Garmin Terrain system provides an "inhibit
mode". This mode is designed to deactivate Premature
Descent Alert/Forward Looking Terrain Avoidance
(PDA/FLTA) visual alerts when they are deemed
unnecessary by the pilot. Flying VFR into an area
where unique terrain exists could cause the system
to annunciate a nuisance alert. Pilots should use
discretion when inhibiting the TERRAIN system
and always remember to enable the system when
appropriate. When Terrain is inhibited, the terrain
page will still be active, but alerts and messages will
not be generated. See the Terrain Alerts section for
more information on terrain alerts.
TERRAIN configured units will restore the "inhibit
state" at startup to the last pilot-selected setting. TAWS
configured units will always start up with TAWS alerts
uninhibited.
