What does the term "handrail" mean in navigation?

In navigation, a "handrail" refers to a linear feature that aids navigation. This can include natural or man-made features such as rivers, roads, or ridges that provide a clear and continuous reference point along a route. Handrails help navigators maintain orientation and ensure they are moving in the intended direction while providing a sort of guide that is easy to follow.

Using a handrail makes it easier to stay on track, especially in unfamiliar terrain, as these linear features are often visible from a distance and can be followed consistently until they intersect with other necessary navigation points or lead to the destination. This concept is crucial in land navigation because it enhances confidence and reduces the chance of becoming lost by providing visible and reliable guides throughout the journey.
