Figure 6-103 TAWS Alerting Disabled
(TAWS Inhibited) Annunciation
Inhibiting/enabling TAWS-B alerting:
1) Select the TAWS-B Page.
2) Select the INHIBIT Softkey to inhibit or enable TAWS (choice dependent on current state).
Or :
a) Press the MENU Key.
b) Select ‘Inhibit TAWS’ or ‘Enable TAWS’ (choice dependent on current state) and press the ENT Key.
If TAWS-B alerts are inhibited when the Final Approach Fix is the active waypoint in a GPS WAAS 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 that the aircraft is
500 feet above terrain or the destination runway elevation. When the aircraft reaches this altitude, the aural
message “Five-hundred” is generated. 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.
NCR alerts are triggered by either excessive altitude loss (Figure 6-104) or sink rate (Figure 6-105). The aural
message “Don’t Sink” or “Too Low, Terrain” 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
Figures 6-104 and 6-105 show the NCR alerting parameters as defined by TSO-C151b
