4. Negative climb rate after takeoff alert (NCR)
The purpose of the Negative Climb Rate (NCR) After Takeoff alert (also referred to as
Altitude Loss After Takeoff) is to provide suitable alerts to the pilot when the system
determines that the airplane is loosing 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 PFD's and Touchscreen Controllers. NCR alerting is
only active when departing from an airport and when the following conditions are met :
-
The height above the terrain is less than 700 feet.
-
The distance from the departure airport is 5 Nm or less.
-
The heading change from the heading at the time of departure is less than
110 degrees.
