KT 76C OPERATION
About Transponders
Your Honeywell Bendix/King
transponder is a radio transmitter and
receiver which operates on radar
frequencies. Receiving ground radar
interrogations at 1030 MHz, it returns
a coded response of pulses to
groundbased radar on a frequency of
1090 MHz.
As with other Mode A/Mode C
transponders, the KT 76C replies with
any one of 4,096 codes, which differ
in the position and number of pulses
transmitted. By “replying” to ground
transmissions, your KT 76C enables
ATC computers to display aircraft
identification, altitude and ground
speed on Enroute, Approach or
Departure Control radar screens.
When the IDENT button is pressed,
your aircraft will be positively
identified to the Air Traffic Controller.
Operating the KT 76C
Before starting your aircraft’s
engine, make sure that the KT 76C
function selector knob, or your
avionics master, is turned to OFF.
After engine start, turn the function
selector knob to SBY (standby). Give
your transponder about 45 seconds to
become operational.
Select the proper reply code by
pressing the desired code entry
buttons. The reply code will be
displayed in the code window. Before
takeoff, rotate the function selector
knob to the ALT (altitude) position for
Mode C altitude reporting to ATC. If
you do not have an encoding
altimeter, rotate the function switch to
ON for Mode A reporting.
Altitude Display
The KT 76C displays Flight Level
Altitude, marked by the letters “FL”
and a number in hundreds of feet, on
the left side of the display. For
example, the reading “FL 065”
corresponds to the altitude of 6,500
feet, referenced to 29.92 inches of
mercury (or 1013 hP) at sea level.
