“FIVE--HUNDRED” AURAL ALERT
The purpose of the aural alert message “Five--Hundred” is to provide an
advisory alert to the pilot that the airplane is 500 feet above terrain. When the
airplane descends within 500 feet of terrain, the aural message
“Five--Hundred” 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 airplane is out of the database coverage area, the annunciation “TAWS
N/A” is generated in the annunciation window and on the TAWS Page. The
aural message “TAWS Not Available” is generated. When the GPS signal is
re--established and the airplane is within the database coverage area, tne
aural message “TAWS Available” is generated.
TAWS Inhibit
TAWS also has an inhibit mode that deactivates the PDA/FLTA aural and
visual alerts. Pilots should use discretion when inhibiting TAWS and always
remember to enable the system when appropriate. Only the PDA and FLTA
alerts are disabled in the inhibit mode.
