5. ”FIVE-HUNDRED” aural alert, altitude voice callout (VCO)
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.
6. 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, the aural message ”TAWS Available” is
generated.
7. 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.
