Which of the following best describes the term "line of sight" in sUAS operations?

The term "line of sight" in sUAS operations refers to the ability to see the drone with the naked eye at all times. This concept is crucial for safe and effective drone operation, as it ensures that the operator can maintain visual awareness of the drone's location and surroundings. Being in visual contact with the drone allows the operator to avoid obstacles, assess weather conditions, and respond to any potential hazards that may arise during flight.

This definition aligns with regulatory requirements in many areas that mandate a visual line of sight for sUAS operations to enhance safety and mitigate risks. Maintaining this visual connection helps in making real-time decisions and avoiding collisions.

In contrast, the other options describe different aspects of drone operation that do not pertain specifically to the concept of line of sight. While the distance from which a drone can be controlled, the range of its camera, and the minimum flying height are all relevant operational parameters, they do not encompass the core meaning of maintaining a line of sight during flight.
