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 aural and visual alerts can also be manually inhibited. Discretion should be used when inhibiting
Terrain-SVS and the system should be enabled when appropriate. When Terrain-SVS is inhibited, the alert
annunciation ‘TER INH’ is shown on the PFD and MFD (Figure 6-157).
Figure 6-157 Terrain-SVS Alerting Disabled

Select the Terrain-SVS Page.
2)
Press the
INHIBIT
Softkey to inhibit or enable Terrain-SVS (choice dependent on current state).
Or
:

If Terrain-SVS alerts are inhibited when the Final Approach Fix is the active waypoint on 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.
