BendixKing GC 360A - Manual (Page 9)

GENERAL INFORMATION
During all navigation operations
using single or dual KNS 660, KLN
88, KLN 90, KLN 90B, KLN 900 or
GNS XLS Long Range Navigation
Systems and your RDS 81, 82, 84,
86, ART 2000 or 2100 weather
radar, the GC 360A generates radar
displays that help you visualize your
aircraft’s position with regard to
important aspects of the flight.
These include: the flight planned
course; weather detected by the
radar; navaids and pilot program-
mable waypoints; and nearby air-
port locations.
The GC 360A is also compatible
with the KNR 634A Nav receiver
and the KDM 706A or DM 441B
DME only in the Nav 2 mode,
though, and only with an LNAV as
Nav 1. Area navigation functions
are not available from the KNR
634A / DME combination, however,
so radar graphics are limited to
active navaids and radial course
displays. The radar graphics unit
receives aircraft heading informa-
tion from the LNAV which must be
operating for the GC 360A to create
Nav 2 graphics.
The joystick-controlled waypoint
function of the GC 360A also
requires the LNAV in order to oper-
ate; therefore it cannot be refer-
enced to the KNR 634A / DME com-
bination. Referenced information
about nearby airports or navaids
that are not part of the flight plan, or
current winds, are also available
only in modes coupled to the LNAV.
The GC 360A generates navigation
data blocks that display the alpha
identifier of the active waypoint
(from the LNAV) or the frequency of
the navaid in use (from the KNR
634A/DME), as well as heading,
course and distance information. A
series of dashes replaces any navi-
gation information unavailable to
the GC 360A.
Throughout all navigation opera-
tions, Nav 1 data references appear
on the radar indicator in cyan (light
blue), with Nav 2 information in yel-
low. Aircraft headings and active
waypoints appear in white, as do
course lines, which the GC 360A
displays to any active waypoint that
is not farther than 1024 nm away.
Range scale numbers are dis-
played in green.
Whenever the active waypoint can-
not be displayed on the radar indi-
cator due to distance or relative
bearing with the GC 360A operating
in its sector mode, an off-screen
waypoint indicator will appear as an
arrow at the bottom of the indicator,
next to the waypoint’s identifier.
Eight pointer positions, spaced 45˚
apart, are possible, so the arrow’s
sensitivity should be considered as
+/-22.5˚. The off-screen waypoint
indicator does not appear when the
GC 360A is operating in its 360˚ cir-
cle mode; instead, refer to the color-
coded RMI dot for waypoint bearing
information.
The radar graphics unit employs
three different symbols to indicate
the nature of navigation references.
