If TAWS-B alerts are inhibited when the Final Approach Fix is the active waypoint in a GPS SBAS approach,

a ‘LOW ALT’ annunciation may appear on the PFD next to the Altimeter if the current aircraft altitude is at
least 164 feet below the prescribed altitude at the Final Approach Fix. See the Flight Instruments Section for
details.

The purpose of the aural alert message “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” aural alert is based on the nearest runway threshold elevation. When the aircraft
is more than 5 nm of the nearest airport, the “Five Hundred” aural alert is based on the height above terrain. 

There are no display annunciations or pop-up alerts that accompany the “Five Hundred” aural 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 aural message “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

Figures 6-84 and 6-85 shows the NCR alerting parameters based on altitude loss and sink rate, respectively,

as defined by TSO-C151b.
