SECTION 10 – HAZARD
AVOIDANCE
Excessive Descent Rate Alert (EDR)
The purpose of the Excessive Descent Rate alert is to
provide suitable alerts when the aircraft is determined
to be closing (descending) upon terrain at an excessive
speed. Figure 10-22 displays the correlation between
height above terrain and descent rate, resulting in the two
EDR alerts. EDR alerts have two levels of severity, caution
(sink rate) and warning (pull-up).

Negative Climb Rate After Takeoff
Alert (NCR)
The purpose of the Negative Climb Rate After Takeoff
alert is to provide suitable alerts to the pilot when the
system determines that the aircraft is losing altitude
(closing upon terrain) after takeoff. The aural message
“Don’t Sink” is given for NCR alerts, accompanied by an
annunciation and a pop-up terrain alert on the display.
Figure 10-23 illustrates the envelope for alerts.

“Five-Hundred” Aural Alert
The purpose of the aural alert message “Five-hundred”
is to provide an advisory alert to the air crew that the
aircraft is five-hundred feet above terrain. When the
aircraft descends 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.
