TAWS-B INHIBIT
TAWS-B PDA and FLTA visual annunciations and voice alerts can be manually inhibited. Use caution when
inhibiting TAWS-B alerting as the system should be enabled when appropriate. When TAWS-B is inhibited,
the system status annunciation 'TAWS INH' appears on the PFD, and in the MFD terrain annunciation window
when terrain display is enabled.

While TAWS-B alerting is manually inhibited (or the TAWS-B system is not available or has failed), the
system may display a 'LOW ALT' annunciation on the PFDs next to the altitude tape if the following conditions
are met:
• The aircraft is on a GBAS SBAS approach.
• The Final Approach Fix is the active waypoint.
• The aircraft is at least 164 feet below the prescribed altitude at the Final Approach Fix..
See the Flight Instruments Section for more details about the 'LOW ALT' annunciation.
FIVE-HUNDRED VOICE ALERT
The purpose of the "Five-hundred" voice alert 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 five nautical miles of an
airport, the "Five Hundred" voice alert is based on the nearest runway threshold elevation. When the aircraft
is more than five nautical miles of the nearest airport, the "Five Hundred" voice alert is based on the height
above terrain (as determined by the GPS altitude and Terrain Database).
There are no display annunciations or pop-up alerts that accompany the voice alert.
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 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:
