What does the term "Line of Sight" mean in drone operations?

The term "Line of Sight" in drone operations refers to the requirement that the operator must be able to see the drone without the use of binoculars or other visual aids. This ensures that the operator maintains situational awareness and can directly assess the drone's surroundings, including its altitude, position, and any potential hazards or obstacles. This requirement is essential for safe operation as it minimizes the risk of accidents and allows for immediate decision-making in response to changing conditions.

While the other options touch upon related concepts, they do not accurately capture the full definition and intent of "Line of Sight." For instance, being within 50 feet of the drone isn't a regulatory requirement, and maintaining a fixed position detracts from the operational flexibility that remote pilots typically need. Thus, having an unobstructed view of the drone without the aid of enhanced visual tools is crucial for safe and compliant drone operation.
