FLTA alerts are automatically inhibited when the aircraft is less than 200 feet above the destination runway
elevation while within 0.5 nm of the approach runway or the aircraft is between runway ends. When Terrain-
SVS alerts are inhibited, the annunciation ‘TER INH’ is shown on the PFD and in the MFD terrain annunciation
window.
FLTA alerts may also be manually inhibited. Use discretion when inhibiting FLTA alerts, as they should be
enabled where appropriate.
Figure 6-136 Terrain-SVS Alerting Disabled
(Terrain-SVS Inhibited) Annunciation
Inhibiting/enabling Terrain-SVS alerting:
1) Select the Terrain-SVS Page.
2) Press the INHIBIT Softkey to inhibit or enable Terrain-SVS (choice dependent on current state).
Or:
1) Select the Terrain-SVS Page.
2) Press the MENU Key.
3) Select ‘Inhibit Terrain-SVS’ or ‘Enable Terrain-SVS’ (choice dependent on current state) and press the ENT Key.
If Terrain-SVS alerts are inhibited or the system is not available or failed when the Final Approach Fix is
the active waypoint in a GPS SBAS approach, a ‘LOW ALT’ annunciation may appear on the PFD next to the
Altimeter if the current aircraft altitude is at least 164 feet below the prescribed altitude at the Final Approach
Fix. See the Flight Instruments Section for details.
