TAWS/TERRAIN
Negative Climb Rate After Takeoff Alert
(NCR)
The purpose of the Negative Climb Rate After Takeoff
alert is to provide suitable alerts to the crew when the
system determines that the aircraft is losing altitude (clos-
ing upon terrain) after takeoff. The aural message "Don't
Sink" is given for NCR alerts, accompanied by an annun-
ciation and a pop-up terrain alert on the display.

"Five-Hundred" Aural Alert

The purpose of the aural alert message "Five-hundred"
is to provide an advisory alert to the crew that the aircraft
is five-hundred feet above terrain. When the aircraft de-
scends within 500 feet of terrain, the aural message "Five-
hundred" is heard. There are no display annunciations or
pop-up alerts that accompany the aural message.

Alert Priority and Aural Alert Message
Summary
TSO-C151b requires the establishment of an internal
priority scheme for alerts. In this way, the more important
alerts will override lesser alerts. Table 7.2.3 shows the
alert priority level in the Garmin TAWS system and gives
a summary of the aural messages.
The aural alert is configurable for either male or female
voice. Different alert text phrases are available for several
alerts. Contact a Garmin authorized service center for fur-
ther information on configuring the alert system.
TAWS System Test
Garmin TAWS provides a manual test for the flight

tion of the aural and visual system annunciation.

An aural message is played giving the test results:
• "TAWS System Test, OK", if the system passes the
test.
• "TAWS System Failure", should the system fail the
test.
