Annunciator Field
NOTE: Inhibit mode deactivates TAWS or
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 TAWS or TERRAIN
system and always remember to enable the
system when appropriate.
Enabling TAWS or TERRAIN:
1) Select the TAWS or TERRAIN Page and press
the MENU Key. ‘Enable Terrain?’ is selected
by default.
2) Press the ENT Key. The TAWS or TERRAIN
system is functional again.
