• As flight plan waypoints are reached, the active leg symbol auto-
matically shifts to the next leg.
• If the flight plan contains more
waypoints than can be displayed
on the screen at one time, the
page will automatically scroll as
progress is made along the flight
plan so that the active leg is
always displayed (figure 4-31).
• The last waypoint in the flight plan is always displayed at the bot-
tom of the FPL 0 page, even if all of the waypoints in the flight
plan can’t be displayed on the page at one time. To view inter-
mediate waypoints, turn the cursor on and use the right outer
knob to manually scroll through all of the waypoints, as desired.
If scrolling is performed all the
way to the end of the flight plan, a
blank waypoint position will exist
so that a waypoint may be added
to the end of the flight plan
(figure 4-32).
4.2.2. TURN ANTICIPATION AND WAYPOINT ALERTING
Prior to reaching a waypoint in the active flight
plan, the KLN 89(B) will provide navigation along
a curved path segment to ensure a smooth transi-
tion between two adjacent legs in the flight plan.
That is, the CDI or HSI left/right deviation will be
referenced to the dashed line in figure 4-33. This
feature is called turn anticipation. The transition
course is based upon the aircraft’s actual ground-
speed and the amount of course angle change
between the two legs. The KLN 89(B) automati-
cally sequences to the next leg after passing the
midpoint in the transition segment.
