DESCRIPTION OE I/)IDICATOR
AND DISPLAY FUNCTIONS
Compass Card
-
Responding to the
input from the slaved directional gyro, this
card rotates within the display
so
that the
aircraft heading is always at the top, under
the lubber line.
Lubber Line
-
A fixed white marker at
the top of the display that indicates aircraft
magnetic heading on the compass card.
Symbolic Aircraft
-
A fixed representa-
tion of the actual aircraft. This miniature air-
craft always points toward the top of the
display and the lubber line.
Selected Course Pointer
-
On this two-
part arrow, the 'head' indicates the desired
VOR or Localizer course and the 'tail' indi-
cates the reciprocal. This pointer is set by
rotating the course select knob.
Course Select Knob
-
Used to rotate
the course pointer to the desired course on
the compass card. This knob corresponds
to the Omni Bearing Selector (OBS) on
standard NAV indicators.
VOWRNAV and LOC Deviation Bar
-
This bar corresponds to the 'left/right" nee-
dle on standard course deviation indicators.
When the aircraft is precisely on the VOR
radial or Localizer course, it forms the cen-
ter section of the selected course pointer
and will be positioned under the symbolic
aircraft. When off course or approaching a
new course, it will move to one side or the
other. Since the entire VOR and Localizer
display rotates with the compass card, the
angular relationship between the deviation
bar and the symbolic aircraft provides a
pictorial symbolic display of the aircraft's
position with respect to the selected course.
Deviation Scale
-
When tuned to a
VOR frequency, each white dot represents 2
degrees of deviation left or right of course.
When tuned to a Localizer, the deviation is
1/2 degree per dot. In RNAV "APR' the
scale is 1/4 nautical mile per dot. In RNAV
'ENROUTE' mode the scale is 1 nautical
mile per dot.*
Heading Select Bug - A movable
orange marker on the outer perimeter of the
display, used primarily to select the desired
heading you wish to fly. This desired head-
ing is coupled to the KFC 150 Flight
Director, KAP 150 Autopilot or KAP 100
Autopilot to provide the 'Heading Select'
function.
Heading Select Knob
-
Used to rotate
the heading select bug to a desired point
on the compass card.
To-From Indicator
-
A white triangle
near the center of the display that indicates,
with reference to the OBS setting, whether
the course selected is 'to' or "from' the
selected VOR station and/or RNAV way-
point.
Dual Glideslop Pointers
-
Chartreuse
triangular pointers on either side of the dis-
play drop into view when a usable glides-
lope signal is received and retract out of
view when the glideslope signal becomes
marginal. During an ILS approach, these
pointers represent the vertical orientation of
the ai craft with respect to the center of the
pointers will align with the center markers
on the glideslop&fsc$e.
