Inhibit Mode<br />
The <strong>Garmin</strong> TERRAIN system provides an ‘inhibit mode’. This mode is designed to deactivate<br />
PDA/FLTA visual alerts when they are deemed unnecessary by the pilot. Flying VFR into an area where<br />
unique terrain exists could cause the system to annunciate a nuisance alert. Pilots should use discretion<br />
when inhibiting the TERRAIN system and always remember to enable the system when appropriate. See<br />
Section 3 for more information on terrain alerts.<br />
To inhibit TERRAIN:<br />
1. Select the TERRAIN Page and press MENU. ‘Inhibit Terrain?’ is selected by default (Figure<br />
2-4).<br />
2. Press ENT. The TERRAIN system is inhibited. The annunciation is displayed in<br />
the terrain annunciator field whenever terrain is inhibited (Figure 2-4).<br />
