Which of the following is a critical consideration when operating near overhead power lines?

When operating near overhead power lines, maintaining an appropriate distance from the lines is crucial for safety. This distance helps to prevent accidental contact with the power lines, which can pose severe hazards such as electrical shock or electrocution. Different types of aerial vehicles, such as cranes and helicopters, have specified minimum safe distances they must maintain from overhead power lines to ensure both operator safety and the safety of those on the ground.

Traffic patterns, weather conditions, and time of day are indeed important factors to consider during aerial operations; however, they do not directly address the immediate risks associated with proximity to power lines. For instance, while poor weather can affect visibility and maneuverability, it does not mitigate the inherent danger of being too close to electrical infrastructure. Similarly, understanding traffic patterns is vital for coordination and safety but is less critical than ensuring a safe distance from power lines to avoid electrical hazards.
