Operating the KT 73
IDENT Button
Marked IDT, the KT 73's Ident
button is pressed when ATC requests
an "Ident" or "Squawk Ident" from
your aircraft. When the Ident button is
pressed while in the GND, ON or ALT
modes, “IDT” will be illuminated on
the display for approximately 18
seconds. An optional Remote Ident
switch may also be installed to
perform the same function.
ID Code
The ATCRBS Transponder
Identification code (squawk code) for
the aircraft is displayed in the Ident
Window on the right side of the
display. Each of the four Transponder
Code Selector Knobs selects a
separate digit of the identification
code.
Reply Indicator
When the KT 73 is replying to a
valid ground Mode S interrogation, the
reply nomenclature “R” will be
illuminated twice per second. When
the KT 73 is replying to a valid
ATCRBS or airborne Mode S
interrogation, the reply nomenclature
“R” will be illuminated once per
second.
Altitude Display
When the ALT mode is selected,
the KT 73 displays the current Flight
Level, marked by the letters “FL” and
a number in hundreds of feet. This is
shown on the left side of the display.
For example, if “FL 071” is displayed,
this corresponds to a reported
pressure altitude of 7,100 feet. Note
that the displayed Flight Level, or
pressure altitude, may not agree with
the aircraft’s baro-corrected altitude
under non-standard conditions. The
Flight Level, or pressure altitude,
reported by the KT 73 will be
corrected as required by the ATC
facility.
