GENERAL
The
Bendix/King
Transponder
(Type
KT
76C),
shown
in
Figure|
1,
is the
airborne
component
of
an
Air
Traffic Control
Radar
Beacon
System (ATCRBS).
The
transponder
enables
the
ATC
ground
controller
to
“see”
and
identify
more
readily
the
aircraft
on
the
radarscope.
The
blind encoder
(SSD1
20-20) (also
shown
in
Figure
1)
enables the
transponder
to
automatically
report
aircraft
altitude
to
ATC.
The
Bendix/King
Transponder
system
consists
of
a
panel-
mounted
unit
and
an
externally-mounted
antenna.
The
transponder
receives
interrogating
pulse
signals
on
1030
MHz
and transmits
coded
pulse-train
reply
signals
on
1090
MHz.
It
is
capable
of
replying
to
Mode
A
(aircraft
identification)
and also
to
Mode
C
(altitude reporting)
interrogations
on
a
selective
reply
basis
on
any
of
4096
information
code selections.
When
a
panel-mounted
SSD1
20-20
Blind
Encoder
-
(not
part
of
KT
76C
Transponder
system)
is
included
in
the avionic
configuration,
the
transponder
can
provide
altitude
reporting
in
100-foot
increments
between
-1000
and
+
20,000
feet.
The
KT
76C
features
microprocessor
and
LSI
(Large
Scale
Integrated)
control.
Mode and code
selection
are
performed
using
the
rotary
knob
and numeric buttons
and all
functions
including
the
flight
level
altitude
are
presented
on
a
gas
discharge
display.
All
display
segments
are
automatically
dimmed
by
a
photocell
type
sensor.
