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 4-30).

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 4-31).

TURN ANTICIPATION AND WAYPOINT ALERTING

Prior to reaching a waypoint in the active flight
plan, the KLX 135A will provide navigation along
a curved path segment to ensure a smooth tran-
sition 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-
32. 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 KLX
135A automatically sequences to the next leg
after passing the midpoint in the transition seg-
ment.
