The layout of the site also depends on the landing space available, the operrations and type of obstacles, unit SOPs, and prearranged flight formations. Because of increased distances between land force units engaged in desert operations, helicopters maybe used to provide air or ground relay, or ffm help deploy ground radio rebroadcast facilities. Do not use a torn glove. Mountainous terrain also restricts communications. However, aviation units with limited pathfinder resources cannot provide continuous support.

Pathfinders are responsible for surveillance of all visible air traffic operating within and around the airspace of the LZ, DZ, or airfield. Altitude, temperature, and humidity determine the density altitude.

Ensure that the cotton buffer is emplaced properly, then milk the keeper down towards the suspension point to secure the sling. He supervises it and, at any time, may supervise the GTA radio operator. For detailed preparation and rigging of the following loads, refer to FM When the load is clear, the pilot begins acceleration while continuing to climb.


When transporting external loads with an UH-1H, use a nylon donut or web ring to attach the load to the aircraft. Such pathfinnder position particularly at night enables the pathfinder ATC to observe the operayions approach of helicopter formations, and it ensures correct alignment with the required landing direction and sufficient obstacle clearance. In such cases, pathfinders are normally employed on a short-term, priority basis wherever they can assist in the accomplishment of major unit missions.

Jungle areas promise heat, humidity, rainy seasons, and other weather conditions that reduce aircraft performance. He may use a reaction force, or he may operarions the source fn the signal using a direction finder. Also, helicopters operating nearby can create turbulence that maybe hazardous to light aircraft.

This applies to both Modes 1 and 2. The pilot must at least fly the final approach leg, regardless of the type approach Table As a guide, a helicopter requires a relatively level, cleared, circular area from 25 to meters in diameter for landing. The longer the slings that attach the load to the aircraft, the less stable the load will be in flight. Also, 57–38 chapter includes terms that are peculiar to ATC tasks. Pick up the nets rather than dragging them across the ground, since dragging them can cause them to snag on something and damage the net or the thing it snags.


Until the last practical moment, pathfinders hood or turn upside down all lights for security. The enemy continuously processes and compares line bearings and plots fixes for pathfinder signals. Aircraft flying in formation, except those flying in trail, and aircraft with a sling load usually form pathinder own approach.

A decision is made on the exact manner in which the equipment is to be transported into the objective area. To determine slope in percentage or degrees, express all measurements in either feet or meters, but not both. Rotor wash stirs up any loose dirt, sand, or snow. Extreme cold and blowing snow pose special problems in ground operations and flight conditions. Sling leg numbering sequence. Do not complete landing or takeoff lift-off.

Pilots are assisted by the electronic and visual navigation aids at the RP if manned.
