GENERAL
The
Cessna
300
Nav/Com
(Type
RT-88õA), shown
in figure 1, oonsists
of a
panol-mounted
recoiver-transmitter
and a single
or dual-pointer
remoto
courae
deviation indioator.
The
set
includes a
?Z0-cba{nel VHF com¡nunications
receiver-
transmltter
and
a 20O-channel VHF
havigation
receiver,
both of
which may
be operated si¡nultaneously.
The bommunications
receiver-transmitter
rooeives
andtransmits
signals between
118.000
and
13õ.97õ MHz in2õ-kHz
steps.
The navigation
reoeiver receives
omni
and
localizer signals
betw€en
108.00
and 117.9õ
MHz in 50-kHz steps. The circuits
required to
interpret
the omni
and locallzer signals are located in the course
deviation
indicator.
Both the
communicatioqs and navigation
operating
frequoncies
are
digitally displayed by
iucandescent readoutE on the front
panel
of
the
Nav/Com.
A
DME receivor-transmitter or a
glide
slope
receiver, or both, may
be
interconnected with the
Nav/Com set
for automatic seloation of
the
associated ÐME or
glide
slope frequency. When
a VOR frequenoy
is
selected on the Nav/Com, associated
VORTAC or VOR-DME station
frequency will
also be selected automatically;
llkewise, if a localizer
frequency is
selected,
the
associated
glide
slope
will be selected automati-
cally.
The course
deviation
indicator
includes either a single-poinüer
and
related NAV flag for
VOR/LOC
indioation
only, or
dual
poiuters
and
related NAV and
GS
flags for
both VOR/LOC and
glide
slope indications.
Both types of oourse deviation indioators
incorporate a back-course
lamp
(BC)
wbicb ligbts when
optional back
course
(reversed
sense) operation is
selected. Both types
may be
provided
with Automatic Radial Centering
whiah, dependlng on how it is
selected, will
a,utoma,tÍca,lly
indicate the
7
bearing TO
or
FROM
the VOR
station.
