Which of the following actions should be taken when setting up a helicopter landing zone?

When setting up a helicopter landing zone (LZ), ensuring that there are no power lines or obstructions is critical for safety and operational efficiency. Helicopters require clear space for both landing and takeoff, as well as adequate room for maneuvering. Power lines and other obstructions pose significant hazards, potentially leading to accidents if pilots are unable to see or avoid these dangers during approach and departure.

Choosing a location that is free from such hazards is therefore essential to prevent accidents, facilitate a safe landing, and ensure that the helicopter can operate effectively. Adequate clearance also provides the crew and any ground personnel the necessary margin of safety, allowing them to perform their duties without the increased risk of injury.

In contrast, setting up an LZ in a soft field could lead to challenges in stability and may complicate the landing process. A crowded area would create additional risks, as too many people could impede operations and create safety hazards during a landing or takeoff. Finally, using a small area does not offer the optimal conditions needed for a helicopter, as it restricts maneuverability, which is crucial for safe flight operations.
