What is the primary goal of maintaining Visual Line of Sight (VLOS) while operating a sUAS?

Maintaining Visual Line of Sight (VLOS) while operating a small Unmanned Aerial System (sUAS) primarily serves to ensure the safety of the operation. By keeping the drone within the operator's direct visual observation, the pilot can make immediate and informed decisions based on what they see in real-time. This is critical for avoiding obstacles, managing the drone's altitude and proximity to people, animals, and property, and responding to any unforeseen circumstances that may arise during flight.

Moreover, VLOS reduces the risk of accidents and enhances situational awareness, significantly contributing to the overall safety of the operation. Regulations typically enforce VLOS requirements to help mitigate risks associated with flying drones in various environments. While factors like battery life and regulatory compliance are important aspects of drone operation, they do not directly safeguard the operational safety in the same manner that maintaining VLOS does.
