Section 7 - Systems Description
The Honeywell KGP 560 Terrain Awareness and Warning System
compares GPS information from the Garmin Navigator (GPS 1) to the
integrated Terrain/Obstacle Database to produce a real-time model of
the surrounding terrain. This “virtual” picture is then sent to the MFD to
provide enhanced situational awareness to the pilot.
The system consists of the 560 GA-EGPWS Processor mounted on
the underside of the pilot-side kickplate, a Terrain/Obstacle Database
integral to the processor, the Configuration Module integral to the
system’s wire harness, and the TAWS annunciator panel mounted on
the lower LH portion of the instrument panel.
The 560 GA-EGPWS Processor is powered by 28 VDC through the 5-
amp SKYWATCH/TAWS circuit breaker on the Avionics Nonessential
Bus.
For a additional system information, refer to the KGP 560 & 860
EGPWS Pilot’s Guide, P/N 006-18254-001, Revision 4 or later.
System Constraints
• If there is no terrain data in the database for a particular area,
then TAWS alerting is not available for that area. The affected
area on the Terrain Awareness Display Page will be colored a
MAGENTA dot pattern.
• If the TAWS has been inhibited (e.g. the pilot selected TERR
INHIBIT) the system will not give aural alerts. The MFD will
display a purple message block with cyan text reading, “TAWS
Inhibited”.
• The TAWS will not be available and the TERR INOP
annunciator will illuminate if any of the following components
are inoperative: MFD, PFD, GPS 1, Transponder, or Attitude
Encoder.

TAWS Annunciator Panel
TAWS terrain annunciations and control functions are incorporated
into the Annunciator Panel. The panel consists of a momentary
pushbutton switch (SELF TEST), an illuminated pushbutton switch
(TERR INHIBIT), and three LEDS for Terrain Warning (TERR WARN),
Terrain Caution (TERR CAUT), Terrain Inoperative (TERR INOP).
• SELF TEST - Provides test function for the TAWS.
• TERR INHIBIT - To inhibit nuisance or unwanted warnings at
airports that are not in the system database, the pilot may
select the TERR INHIBIT switch. Although selection will inhibit
all TAWS visual and aural alerts, the Terrain Awareness Display
will remain functional with the message “Warnings Inhibited”
displayed on the MFD. When activated the switch will illuminate
amber.
• TERR INOP - Indicates the TAWS inoperative. When activated
the LED will illuminate amber.
• TERR CAUT - Indicates a possible terrain or obstacle conflict
within 40-60 seconds. When activated the LED will illuminate
amber.
• TERR WARN - Indicates a possible terrain or obstacle conflict
within 30 seconds. When activated the LED will illuminate red.
The annunciators are dimmed via the instrument panel lighting
dimmer switch. The TAWS annunciator panel is powered by 28 VDC
through the 2-amp ANNUN circuit breaker on the Essential Bus
Alert Priority
When any of the TAWS aural alerts are in progress, all aural TRAFFIC
alerts are inhibited.
Advisory Callout
The advisory callout “FIVE HUNDRED”, occurs at approximately 500
feet AGL.
