SECTION 1
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 (SSD120-20) (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.
