Features - Honeywell BENDIX KING KT 73 Installation Manual

Preliminary - Subject To Change Without Notice
BENDIX/KING
The KT 73 has an Air/Ground discrete which, when connected to a strut switch on the aircraft, can
disable ATCRBS and Mode S All-Call replies when the aircraft is on the ground. A front panel
switch position, 'GND', can also be used by the pilot instead of the strut switch.

Features

The KT 73 is capable of interfacing to the Traffic Information Service (TIS). This data link is intend-
ed to improve the safety and efficiency of "see and avoid" flight by providing the pilot automatic
display of nearby traffic and warnings of any potentially threatening conditions. The display of TIS
traffic requires a compatible MFD, currently the KMD 540. TIS is only provided within the service
volume of most Mode S terminal radar facilities and only in the contiguous United States (US).
The KT 73 is also capable of Automatic Dependent Surveillance - Broadcast (ADS-B) operation
which allows an aircraft or surface vehicle to transmit position, altitude, vector, and other informa-
tion for use by other aircraft, surface vehicles, or ground facilities. ADS-B requires a source of
GPS data, currently the KLN 94/KLN 900 are the only acceptable sources. The KT 73 has the
capability to transmit extended squitters and to operate in the Extended Squitter/Non Transponder
mode.
The KT 73 has the ability to enter and display an 8-digit alpha-numeric Flight ID code. The Flight
ID information is entered by the pilot via front panel controls or is received from an ADLP. Flight
ID is selected for display from the front panel.
When the KT 73 receives Mode A interrogations from the ground radar facility, it will transmit a
coded group of pulses which consist of a four digit identification number that has been assigned
by the Air Traffic Controller. This code is entered into the KT 73 by the pilot and is transmitted
back to the ground as a Mode "A" reply. This coded information is presented on the ground radar
display at the appropriate range and azimuth. The Air Traffic Controller can then identify each air-
craft that is transponder equipped by its distinct coded number.
The VFR code, aircraft address, maximum air speed, display adjust, and installation parameters
can be programmed from the front panel of the KT 73 and stored in nonvolatile memory. Pilot ad-
justments include VFR code, Flight ID, and display brightness. Installation adjustments include
aircraft address, maximum airspeed, and configuration parameters (refer to Section 3 for specific
programming sequences). A configuration module is provided to store the address with the rack,
allowing units to be swapped from rack to rack without having to reprogram the aircraft address
or other configuration parameters.
The flight ID information can be entered by the pilot via front panel controls. Flight ID can be se-
lected for display from the front panel.
The KT 73 has BITE (Built-In-Test-Equipment) which constantly monitors the operational health
of the unit. When a fault is detected, the transponder will display an error code on the front panel
display in order to help diagnose problems. When a critical fault is detected, the unit will turn on
an amber FAIL light on the front of the unit.
