Numerical displays are 7-segment
gaseous discharge lights. Modes and
operating status information are
annunciated by individually lighted
abbreviations.
The KNS
80 illustration above
shows all display legends lighted. In
actual operation, only the appropriate
operating legends will be annunciated.
Using the illustration above as a
reference, they are:
Controls:
1. Power ON/OFF and audio
volume control. Pull out for VOR/LOC
IDENT tone.
2. Data input
controls for selection
of VOR/LOC frequency, waypoint radial
and waypoint distance. DME is
automatically tuned with selection of
the paired VOR frequency.
3. VOR is a momentary push
button. Push for conventional
VOR/DME operation. DME is
automatically tuned and distance,
groundspeed and time-to-station
(TTS)
to the VORTAC station will be displayed
upon lock on. The Course Deviation
Indicator (CDI) will display conven-
tional angular crosstrack deviation
from your selected course
(210"
full scale).
Push VOR again for VOR/PAR
function. Operation will be identical to
VOR/DME operation except the CDI
will display crosstrack deviation
25 nm
full scale from the selected course.
Course width will be constant (linear)
irrespective of distance from VORTAC.
Depressing VOR cycles between
VOR and VOR/PAR operation.
4. RNAV is a momentary push
button. Push for conventional RNAV
Enroute (RNV/ENR) operation.
Distance, groundspeed and
TTS to the
waypoint will be displayed. The CDI
will
display a linear crosstrack deviation
*5 nm full scale from selected course
to waypoint.
Push RNAV a ain for RNAV
Approach (RNV/A!R) function.
Operation in RNAV Approach is the
same as RNV/ENR except the CDI will
display crosstrack deviation as
21%
nm full scale. Both provide constant
course width (linear) deviation.
Depressing RNAV cycles between
RNVlENR and RNVIAPR.
5. HOLD is an alternate action
push button. When in the depressed
position, it retains the ori inal DME
frequency (HLD)
so DMZoperation
on the original frequency can be
continued while selecting other VOR
or ILS frequencies.
6. DSP is a momentary push
button that selects for display (in order)
any one of four "data storage bins" in
which VOR/LOC frequencies, with or
without waypoint parameters, may be
inserted. Each "storage bin" can be
called up as desired from 1 to
4, then
back
to 1.
7. DATA is a momentary push
button that causes either frequency,
waypoint radial or waypoint distance
to be displayed, in that sequence, for
4
