Which of the following lists all factors to consider when selecting the number of landing sites?

• A. Mission, Terrain, Number of aircraft, and amount of equipment to be sling loaded
• B. Weather, Time of day, Pilot experience, and terrain
• C. Fuel load, Aircraft color, Weather, and distance to drop zone
• D. Mission, Weather, Number of aircraft, and fuel on hand

Answer: (A)

The key idea is that the number of landing sites is driven by how the mission is to be accomplished, the terrain where the sites will be located, how many aircraft you have available, and how much equipment must be sling loaded. The mission sets what delivery needs and timing are required, which influences how many sites or passes are needed. Terrain shapes where you can safely place sites and how far apart they must be, so complex or obstacle-rich terrain often requires more sites or carefully spaced locations. The number of aircraft available determines how many loads you can deliver in a given window and how quickly you can move between sites. The total amount of equipment to be sling loaded affects load planning and site occupancy because heavier or more numerous loads may require additional sites to keep loads within weight and distance limits and to maintain safe operations. Together these factors form the practical basis for sizing landing sites before the operation starts. Other options include elements that influence safety or timing but don’t directly define how many landing sites are needed, or include irrelevant items, so they don’t fit as well.
