A head bearing helps to identify which of the following?

A head bearing is a navigational concept that helps in identifying a point of reference, typically a navigational aid or GPS point, on an approach track. This involves determining the direction to a known point from the vessel's current position, which is crucial for maintaining the correct course and ensuring safe navigation in proximity to navigational aids or established routes. By utilizing head bearings, mariners can orient themselves in relation to these points, enhancing situational awareness and allowing for more precise navigation.

When approaching a point, knowing the head bearing allows the navigator to confirm they are on the intended track toward a navigational aid, thereby promoting safety and navigation efficiency. This practice helps in managing the vessel's approach and aligning it correctly with the designated course, especially in visually challenging conditions.
