Because the pilot must focus on the problem with the aircraft, the pathfinder helps by moving other air traffic away from the one having the problem, which has first priority.
Every single user inspects every single sling before and after every single use. The following message is for another aircraft. Because no aircraft plan to land pathfnider, and because the utility or lift aircraft know the LZ and screen team’s location pathfindr communications over internal UHF or VHF radio nets, the screening helicopters need not contact the pathfinder.
To avoid the buildup of a snow cloud, the pilot puts the load on the ground as quickly as possible. Desert winds generally calm down for an hour or two around sundown.
This beacon allows the party to offer long-range guidance. If a priority for installing these aids is required due to limited personnel or other factors, then the following priority is used. They monitor these radio nets continuously, unless directed otherwise, tm they complete operations at the site.

In the defense, helicopters can move reinforcements and reserves rapidly. When possible, to keep informed about changing situations that could influence their operations, pathfinders monitor supported unit command radio nets.
Pathfinders may have to fight their way to these rally points and reorganize. He supervises the inspection of the load for proper routing of the slings and proper preparation. For more detailed information on the climate, terrain, and operational aspects of these areas, see FMFMand FM To eliminate this unsafe phenomenon, avoid marking LZs with a single light. High drag coefficients will reduce the airspeed of the aircraft, will take longer to complete the task or cause it to be incomplete because allotted time has expired, and could oossibly endanger the aircraft and its crew.
Use a canvas insert when carrying items small enough to slip through the netting: If the emergency develops before initial contact, operational security requires a full information exchange as in a standard transmission. ATC light signals on or near LZ.

Other considerations include vertical air currents, escape routes, terrain contour and obstacles, and the position of the sun. WIND Figure It is the final navigational checkpoint for aircraft approaching the landing site or approaching air-delivery facilities in an LZ or DZ.
If the tactical situation permits, the GTA radio operator advises the pilot of operationd surface conditions so the pilot can plan how to approach. The site is surveyed for vines, trees, and other obstructions in the approach path and near the touchdown point.
In the mountains, density altitude can vary a lot between PZs and LZs. Using the echelon left or right landing formation reduces the effect of snow clouds also called “whiteouts” on subsequent landings. An approach directly into the sun must be avoided when the sun is low on the horizon.
His sequence of reply to an initial call-up by an aircraft is as follows: Trained personnel can rappel from helicopters hovering over unsuitable landing areas. The pathfinder most often encounters this type approach. Pull the free-running end of the sling around the point of attachment. When inspecting the Type IV link assembly, look for the following deficiencies: Whenever possible, pilots should land upslope rather than downslope.
FM Chptr 4 – Helicopter Landing Zones
It is usually limited to short movements by small elements. When aircraft sizes vary, pathfinders separate landing points by the most generous measure, allowing meters from center to center of the landing points Figurepage Lighted night landing symbols as the pilot would see them from different approach angles. Therefore, maintaining radio silence within the LZ is important. Size 2 landing point 35 meters.
During flight at less extreme temperatures, this ice begins to loosen and fall off. Additional lights are provided for touchdown points of other helicopters in the flight.
