6-17
solely on the present radial and the defined arc dis-
tance 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 LOAD IN FPL, press E. 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 90B may give the message:
REDUNDANT WPTS IN FPL
EDIT ENROUTE WPTS
AS NECESSARY
Examine the flight plan and, if practical, observe the
Super NAV 5 page to make sure that the sequence of
waypoints does not have any unnecessary legs in it.
6. The KLN 90B will now provide guidance to the arc
intercept point. The Super NAV 5 page displays the entire
arc on the screen. The portion 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 intercept
point and the end of the arc is drawn with the normal solid
line (figure 6-26).
7. In some cases ATC may provide radar vectors to the
arc. The KLN 90B 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 Super
NAV 5 page or from the FPL 0 page. The dashed line
displayed on the Super NAV 5 page will help you to deter-
mine if ATC is giving you correct vectors.
• From the Super NAV 5 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 left
cursor and move it over the first waypoint of the
arc.
• From either page press @. This will change
the waypoint to read MOVE? (figure 6-27). If it is
desired to recompute the arc intercept point then
press E. If a new arc intercept point is not
desired then press @ again.
• If E was pressed, then the KLN 90B will
calculate an arc intercept point based on the
present track of the aircraft over the ground.
