TAWS-B 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
displays the 'TAWS N/A' annunciation, and issues the "TAWS Not Available" voice alert. When the GPS
signal integrity returns and the aircraft is within the database coverage area, the system issues the voice alert,
"TAWS Available".
