for alerting based on speed, distance, and other param- eters.

Figure 10-20 PDA Alerting

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 10-21 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).

SECTION 10 – HAZARD

AVOIDANCE

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.

“Five-Hundred” Aural Alert

The purpose of the aural alert message “Five-hundred” is to provide an advisory alert to the aircrew 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.
