Interception lines in visual navigation serve as predetermined routes or points that a Pilot can use to reorient themselves in case they become disoriented. These lines or paths (also called "line features") are usually based on prominent landmarks or navigational aids that are easy to locate from the air. Their purpose is to provide a clear and reliable means of regaining proper orientation, ensuring that Pilots can safely and efficiently find their way even if they lose track of their intended course.

If the orientation is lost during helicopter flight operations, the Pilot should continue with the planned heading to the next interception line and then reorient from there.

With this action, the helicopter is maintained on a known trajectory, reducing the chance of further disorientation. By sticking to the planned heading, the Pilot can gradually navigate to a predefined interception line, which can then be used as a reference point to re-establish the correct course. This method leverages the existing flight plan and navigational aids to regain orientation safely and efficiently.
