With most fms you do not actually overfly the waypoints you start the turn just before reaching the way point so you in effect turn early before you reach the waypoint and cut the corner the 'overfly' function ensures that the aircraft doesn't cut the corner but does go overhead the specified waypoint before turning on to the next track exemple 247 manually selecting a flight plan waypoint to fly over when sequencing it instead of flying by at the transition.manually selecting a flight plan waypoint to fly over when sequencing it instead of flying by at the transition.
