1.2
GENERAL
DESCRIPTION
The
King
KT
76
and
KT
78
Transponders
are
radar
beacon
equipment
desi
g
ned
to
fulf
i
ll
the
role
of
the
airborne
beacon
under
the
requirements
of
the
Ai.r
Traffic
Control
Radar
Beacon
System
(ATCH.BS).
The
KT
76/78
Transponders
are
capable
of
locating
the
user
throu
gh
the
air
traffic
controller.
Range
and
azimuth
are
established
by
the
return
from
the
transponder's
pulsed
transmitter
in
reply
to
n.
routine
interrogation
from
the
ground
radar
site.
The
transponder
reply
is
a
set
of
pulses,
selected
in
number,
and
positioned
in
time,
one
with
respect
to
the
other
(not
entirely
unlike
telegraphy).
Information
is
conveyed
to
the
ground
in
this
manner.
An
identity
code
number,
s
elected
at
the
front
panel
by
the
pilot
is
transm.itted
as
a Mode A
reply.
Mode
C,
altitud
e
reporting,
is
an
additional
capability
designed
into
the
transponder.
However,
in
order
to
convey
altitude
information,
the
transponder
must
be
lised
in
conjunction
with
a
reporting
altimeter
and
operated
in
"ALT"
function.
An
additional
feature
of
the
transponder
and
beacon
system
is
the
S.
P.
I.
(Special
Pulse,
Identification).
After
pressing
the
i
dent
button
the
transponder,
when
interrogated,
will
rep
ly
with
a
special
pulse
that
will
cause
the
associat
ed
pip
on
the
controllers
display
to
"bloom"
effecting
immediate
recognition.
