Figure 3D-43. Turn Anticipation
(2) To use the turn anticipation feature, start
the turn transitioning to the next leg in the flight plan at
the very beginning of turn anticipation. This occurs
when the external waypoint alert annunciator or the
active waypoint identifier on the Super NAV 5 page
stops flashing and goes on steady. The KLN 90B will
generate a message on the message page for the new
desired track to select on the EHSI: ADJ NAV IND
CRS TO 123o. A message will not be given if the
change in desired track is less than 5 or the KLN 90B
is interfaced with an EHSI having a course pointer that
is automatically slewed to the correct desired track.
(3) The desired track displayed on the NAV 3
page also changes to the value of the next leg at the
beginning of turn anticipation. Turn anticipation
becomes inactive when transition to the next leg has
(4) The KLN 90B can read the selected
course set on the external EHSI. The KLN 90B will
flash the value of the desired track on both the NAV 3
and the Super NAV 5 pages when the desired track
and the selected course differ by more than 10°. Set
the selected course to match the desired track. This
will ensure that the orientation is always pictorially
(5) If desired, turn anticipation may be
disabled, or enabled, on the SET 6 page.
i. Viewing the Waypoint Pages for the Active
Flight Plan Waypoints. The waypoint pages for each
of the waypoints in the active flight plan may be
displayed by selecting the Active Waypoint page with
the right outer knob. Refer to Figure 3D-44. When the
ACT page is first selected, the waypoint page for the
active waypoint will be displayed. The sequence
number of the waypoint in the flight plan is
annunciated with a number to the left of the identifier.
An arrow to the left of the waypoint number designates
the active waypoint. The letter to the far right of the
identifier designates the type of waypoint: A airport,
V VOR, N NDB, I intersection, S supplemental,
or T terminal. For VORs having DME capability, the
letter D is displayed between the VOR identifier and

Figure 3D-44. The Active Waypoint Page
To view the other waypoints in the flight plan,
pull the right inner knob to the out position and turn it
to view each of the waypoints in the order they are in
the active flight plan. For airport waypoints, the right
inner knob may be pushed back to the in position and
rotated to display any of the eight airport pages.
Pulling the knob back out will allow further scanning of
the waypoint pages in the active flight plan.
j. Direct To Operation on the Active Flight
Plan. When DIRECT TO operation to a waypoint on
the active flight plan is selected, the system will
automatically resume navigation along the flight plan
Waypoints that exist prior to the DIRECT TO waypoint
in the active flight plan are bypassed. Navigation on
the active flight plan will not be resumed if the DIRECT
TO operation is to a waypoint that is not in the active
(1) Any of the methods previously described
for initiating direct to operation may be used. The
following procedure is the easiest for this application.
1. Select the FPL 0 page on the left side.
2. Press the left CRSR button and then
use the left outer knob to position the
cursor over the desired waypoint.
Refer to Figure 3D-45.
3. Press the D button. The waypoint
page for the selected waypoint will be
displayed on the right side. Refer to
