What does a circled waypoint symbol on an approach chart indicate about the Missed Approach Point (MAP)?

A circled waypoint symbol on an approach chart indicates that it is a fly-over waypoint. This specific design signifies that the aircraft must actually fly over the waypoint before proceeding to the next segment of the approach or maneuver. In other words, the pilot must pass directly over the waypoint and cannot begin the turn or transition to the next leg of the approach until the aircraft has reached the waypoint itself.

This is crucial for maintaining the proper flight path and ensuring safe navigation, especially in complex airspace environments where precise adherence to waypoints is necessary. Whereas a fly-by waypoint allows for a turn to be initiated before reaching the waypoint, which might not require the aircraft to directly overfly it, the circled symbol makes it clear that the pilot must complete the fly-over before any subsequent maneuvers. Understanding this distinction helps in effective navigation and compliance with the procedures laid out in the approach charts, enhancing safety during flight operations.
