Excessive Descent Rate Alert (Edr); Negative Climb Rate After Takeoff Alert (Ncr); Five-Hundred" Aural Alert - Garmin G1000 Columbia 350 Cockpit Reference Manual

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 10-19 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).

annunciation and a pop-up terrain alert on the display.
