HAZARD AVOIDANCE
TAWS-B INHIBIT
TAWS-B PDA and FLTA aural and visual 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 alert
annunciation 'TAWS INH' is shown on the PFD, and in the MFD terrain annunciation window when terrain
display is enabled.
Figure 6-151 TAWS-B Alerting Disabled (TAWS-B Inhibited) Annunciation
Inhibiting/enabling TAWS-B alerting:
1)
Select the TAWS-B Page.
2)
Press the
MENU
Key.
3)
Select 'Inhibit TAWS' or 'Enable TAWS', depending on the current state, and press the
ENT

INHIBIT
Softkey to inhibit TAWS.
If TAWS-B alerts are inhibited when the Final Approach Fix is the active waypoint during 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.
FIVE-HUNDRED AURAL ALERT
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
(as determined by the GPS altitude and Terrain Database).
There are no display annunciations or pop-up alerts that accompany the aural message.
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 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 5 nm or less
• Heading change from the departure heading is less than 110 degrees
