route of waypoints, the autopilot will steer to the first waypoint
in the route after you accept the first waypoint as the location to
steer towards. When you arrive at the waypoint, the autopilot
will output an audible warning, display an alert screen with the
new course information, and automatically change course onto
the new leg.

verify that the upcoming course change is acceptable. This is a
safety feature.
