AlliedSignal Bendix/King KLN 89, Pilot'S Manual

Page: 117 / 242

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 or waypoint page displaying the
active waypoint identifier (figures 4-34
and 4-35). 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 transition to the
next leg in the flight plan at the very beginning of turn anticipation.
This occurs when the external waypoint alert annunciator stops
flashing and goes on steady. At this time, the KLN 89(B) will notify
you with a message on the Message page of the new desired track
to select on your HSI or CDI.
*Adj Nav Crs to 123°
A message will not be given if the change in desired track (course
change) is less than 5°.
The desired track (DTK) displayed on the NAV 1 page and optionally
on the NAV 4 page also changes to
the value for the next leg at the begin-
ning of turn anticipation. Turn
anticipation becomes inactive when
transition to the next leg has been
made.
If desired, turn anticipation may be
disabled (or enabled) on the Setup
(SET) 4 page by pressing the
B
button and then rotating the right
inner knob to change back and forth
between ENABLED (figure 4-36) and
DISABLED (figure 4-37). If turn
anticipation is disabled, navigation is provided all the way to the way-
point, and waypoint alerting occurs approximately 36 seconds prior to
actually reaching the waypoint.
