TAWS

‘FIVE-HUNDRED’ AURAL ALERT

The purpose of the aural alert message “Five-Hundred” is to provide an advisory alert to the pilot that the air- craft is 500 feet above terrain. When the aircraft descends within 500 feet of terrain, the aural message “Five-Hun- dred” is generated. There are no display annunciations or pop-up alerts that accompany the aural message.

TAWS NOT AVAILABLE ALERT

TAWS 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 annunciation ‘TER N/A’ is generated in the annunciation window and ‘TERRAIN NOT AVAILABLE’ is generated on the TAWS Page (Figure 13-10). The aural message “TERRAIN Not Available” is generated. When the GPS signal is re-established and the aircraft is within the database coverage area, the ‘TER N/A’ visual annunciation is removed (there is no associated aural message).

TAWS FAILURE ALERT

TAWS continually monitors several system-critical items such as database validity, hardware status, and GPS status. If the terrain/obstacle database is not available, the aural message “TAWS System Failure” is generated along with ‘TER FAIL’ in the annunciation window, and ‘TERRAIN FAILED’ on the TAWS Page (Figure 13-11).
