Anticipation

The Apollo GX will provide information for you to
smoothly transition from one flight plan leg to
another. Turns are drawn on the moving map. You
will receive a message about ten seconds before the
turn. The message will count down to the beginning
of the turn. The message shown below indicates that
you are arriving at the SLE waypoint, the next leg
desired track is 93°, and you should start your turn in
about nine seconds.

Standard Turn Operation
While you are in the turn, the desired track and cross
track are determined based on the turn. Turns are
made at three degrees per second if the ground speed
is under 250 knots. If ground speed is greater than 250
knots, the turn rate is set at 1.5 degrees per second.

Turn anticipation is not shown if the end of the turn
extends beyond the beginning of the next anticipated
turn. That is, if the two waypoints are too close, turn
anticipation will not be shown. Turn anticipation
curves are only drawn when the turn is greater than
5°. If the turn is greater than 120°, the Apollo GX will
generate a step turn message prior to the waypoint.
