Terrain Awareness and Warning System (TA WS-B)- Optional (continued)
System Status:
During G 1000 power-up, TA WS-B conducts a self-test of its aural and
visual annunciations. The system test can also be manually initiated by
selecting the TA WS-B Page then depress the MENU key, then select the
"Test TA WS" option. An aural alert "TA WS System Test OK'' or "TA WS
System Failure" is issued at test completion, regardless of whether the
test was initiated automatically or manually. TA WS-B System Testing is
disabled when ground speed exceeds 30 knots.
TA WS-B requires the following to operate properly:
• A valid terrain/obstacle/airport terrain database
• A valid 3-D GPS position solution
If a valid 3-D GPS position solution and vertical accuracy requirements are
•
not attained or the aircraft is out of the database coverage area, a TA WS NI A
annunciation will appear on the TA WS-B Page and the aural annunciation
"TA WS Not Available" is heard. When the GPS signal is re-established and
the aircraft is within the database coverage area, the aural message "TA WS
Available" is heard.
