WAYPOINT ALERT
The Waypoint Alert will flash
the next desired track (NEXT
DTK) when the estimated time
to the next waypoint is about
15 seconds as shown in Figure
1-63. Turning to establish the
NEXT DTK will aid in inter-
cepting the next leg of the flight
plan.
If the waypoint is being dis-
played in a Data Field the WPT field will flash annunciating the Waypoint
Alert.
When viewing the Flight Plan Page the arrow indicating the current leg
will flash to annunciate the Waypoint Alert.
If an external Waypoint Alert annunciator is installed in the aircraft, it will
also flash.
TURN ANTICIPATION
When Turn Anticipation is
enabled in Navigation Setup, it
will provide turn guidance to a
new course for intercepting the
next leg of the flight plan.
Waypoint Alerting will begin
when the estimated time to the
start of the turn is about 20
seconds. As previously dis-
cussed, the Waypoint Alert will
be annunciated by flashing the
next desired track (NEXT
DTK) window as in Figure 1-
64. When the computed turn
point is reached TURN TO will
displayed as shown in Figure
1-65. The required bank angle
to follow the arc will normally
be between 3° and 25°
depending on aircraft speed
and the amount of course
change.
