Hazard Avoidance SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS AVOIDANCE MANAGEMENT AUDIO & CNS FLIGHT HAZARD Inhibiting Terrain SVT alerting while an alert is occurring: Touch the Inhibit Terrain Button on the Terrain SVT pop-up window. If Terrain SVT alerts are inhibited when the Final Approach Fix is the active waypoint in a GPS SBAS approach, the system may show a 'LOW ALT' annunciation 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. System Status During power-up, Terrain SVT conducts a system test of its aural and visual annunciations. The system issues an aural alert when the test is finished. Terrain SVT continually monitors several system-critical items such as database validity, hardware status, and GPS status. If the terrain/obstacle database is not available, the system generates the aural message "Terrain System Failure" along with the 'TER FAIL' alert annunciation. Terrain SVT requires a 3-D GPS navigation solution along with specific vertical accuracy minimums. Should the navigation solution become degraded or if the aircraft is out of the database coverage area, the system generates the aural message "Terrain System Not Available" along with the visual 'TER N/A' annunciation. When sufficient GPS signal is returns and the aircraft is within the terrain/obstacle database coverage area, the system generates the aural message "Terrain System Available".
