What is one responsibility of the Pathfinder at a landing zone (LZ)?

At a landing zone (LZ), one of the primary responsibilities of the Pathfinder is to mark the site. This task is crucial because it ensures that the helicopter pilot has a clear visual reference to safely land the aircraft, particularly in challenging environments where visibility may be compromised. Proper marking typically involves using various signaling techniques and visual aids to denote the landing area, highlight potential obstacles, and indicate the safest approach and departure paths for the helicopter. This role is vital in facilitating the efficient and safe operation of air support in various mission profiles, ensuring personnel can be transported or supplies delivered without incident.

While preparing load plans, instructing pilots on inflight procedures, and conducting safety drills are important tasks in aviation operations, marking the site directly aligns with the immediate functions of the Pathfinder during landing zone operations.
