What is the main difference between fly-over and fly-by waypoints?

Fly-over waypoints are represented as solid lines on navigation charts, indicating that an aircraft must navigate directly over the waypoint before proceeding on its course. This requires precise position management, as the aircraft needs to reach the waypoint to ensure proper navigation. Conversely, fly-by waypoints are indicated with dashed lines, allowing the aircraft to turn before reaching the waypoint, which means they do not require a direct overhead pass. This distinction helps pilots understand how to navigate each type of waypoint effectively, ensuring safer and more efficient flight paths.

The visual representation of fly-over and fly-by waypoints aids pilots in their decision-making, emphasizing the necessity for different levels of precision and maneuvering related to each waypoint type. Understanding these symbols is crucial for maintaining safe separation from waypoints, especially in complex airspace scenarios.
