HAZARD AVOIDANCE
NEGATIVE CLIMB RATE AFTER TAKEOFF ALERT (NCR)
The
Negative Climb Rate (NCR) After Takeoff
alert (also referred to as “Altitude Loss After Takeoff”)
provides alerts when the system determines the aircraft is losing altitude (closing upon terrain) after takeoff.
The voice alert
“Don’t Sink”
is given for NCR alerts, accompanied by visual annunciations. NCR alerting is only
active when departing from an airport and when the following conditions are met:
»
Height above the terrain is less than 700 feet
»
Distance from the departure airport is 5 nm or less
»
Heading change from the departure heading is less than 110 degrees
»
NCR alerts can be triggered by either altitude loss or sink rate
