• 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 4-32).
• The last waypoint in the flight plan is always displayed
at the bottom of the FPL 0 page, even if all of the way-
points in the flight plan can’t be displayed on the page
at one time. To view intermediate waypoints, turn the
left cursor function on and use the left 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 4-33).
4.2.2 Turn Anticipation And Waypoint Alerting
Prior to reaching a waypoint in the active flight plan, the
KLN 900 will provide navigation along a curved path seg-
ment to ensure a smooth transition 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-
34. This feature is called turn anticipation. The transition
course is based upon the aircraft’s actual groundspeed
and the amount of course angle change between the two
legs. The KLN 900 automatically sequences to the next
leg after passing the midpoint in the transition segment.
Approximately 20 seconds prior to the beginning of turn
anticipation, the arrow preceding the active waypoint
identifier will begin flashing on the FPL 0 page and on any
Navigation page, Distance/Time page, or waypoint page
displaying the active waypoint identifier (figure 4-35). On
the Super NAV 5 page, the entire active waypoint identi-
fier will start to flash. This is called “waypoint alerting”. If
an external waypoint alert annunciator is mounted in the
aircraft, this annunciator will begin flashing at the same
time.
To utilize the turn anticipation feature, start the turn transi-
tioning 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. At this time the KLN 900 will notify you
with a message on the Message page of the new desired
track to select on your HSI or CDI.
ADJ NAV IND CRS TO 123°
A message will not be given if the change in desired track
(course change) is less than 5°. In addition, a message
will not be given if the KLN 900 is interfaced with an EHSI
or HSI having a course pointer that is automatically
slewed to the correct desired track.
