BendixKing KLN 89B - Pilots Guide - Manual (Page 183)

CAUTION: The KLN 89B does not take into account the geome-
try of the active flight plan when determining the arc intercept
point. This point is defined solely on the present radial and the
defined arc distance from the reference VOR. For this reason it
is better to delay selecting approaches that contain DME arcs
until the aircraft is closer to the destination.
4. With the cursor over ADD TO FPL 0?, Press F . The approach
will be loaded into the active flight plan just like any other
approach would be.
5. After the approach is loaded into the flight plan the KLN 89B may
give the message:
*Redundant Wpts In FPL
Edit En Route Wpts
As Necessary
This message is given because very often it will be necessary to
edit the active flight plan to ensure that proper waypoint sequenc-
ing occurs. Examine the flight plan and, if practical, observe the
NAV 4 page to make sure that the sequence of waypoints does
not have any unnecessary legs in it.
6. The KLN 89B will now provide guidance to the arc intercept point.
The NAV 4 page displays the entire arc on the screen. The por-
tion that is between the beginning
of the arc and the arc intercept is
drawn with a dashed line. The
part that is between the arc inter-
cept point and the end of the arc
is drawn with the normal solid line
(figure 5-24).
7. In some cases ATC may provide radar vectors to the arc. The
KLN 89B provides a means to define a new intercept point based
on the current track of the aircraft over the ground. This can be
done from either the NAV 4 page or from the FPL 0 page. The
dashed line displayed on the NAV 4 page will help you to deter-
mine if ATC is giving you correct vectors.
• From the NAV 4 page, pull out the right inner knob to bring
up the waypoint scanning window.
• Turn the right inner knob until the first waypoint of the arc is
displayed, D011L in this example. For approaches this will
have a small (i) appended to the waypoint name. If the
recalculation is to be done from the FPL 0 page, then turn on
the cursor and move it over the first waypoint of the arc.
