FIVE HUNDRED ALTITUDE VOICE CALLOUT ALERT
The purpose of the voice alert
“Five-hundred”
is to provide an advisory alert of when the aircraft descends
to within 500 feet above the terrain or runway threshold. When the aircraft is within 5 nm of an airport, the
“Five Hundred”
voice alert is based on the nearest runway threshold elevation. When the aircraft is more than
5 nm of the nearest airport, the
“Five Hundred”
voice alert is based on the height above terrain.
There are no display annunciations or pop-up alerts that accompany the
“Five Hundred”
voice alert.
NEGATIVE CLIMB RATE AFTER TAKEOFF ALERT
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 an annunciation and a pop-up terrain
alert on the display. 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 2 nm or less
»
Heading change from the departure heading is less than 110 degrees
The following two figures shows the NCR alerting parameters based on altitude loss and sink rate,
respectively, as defined by TSO-C151b.
