What is essential for safe UAS operation in specific environments?

Proper coordination with ground personnel is crucial for safe UAS operation in specific environments as it ensures clear communication and collaboration, which is vital for managing the many variables that can affect flight safety. Ground personnel can provide real-time situational awareness about obstacles, other air traffic, or changing conditions in the environment. They can also assist with the prevention of accidents by monitoring the area where the UAS is operating.

In certain environments, particularly those that are congested or complex, such as urban areas or near construction sites, the risk of collisions and accidents increases. Having ground personnel to coordinate with helps mitigate these risks by allowing the remote pilot and ground crew to maintain awareness and respond swiftly to any hazards.

Other options, while they may be beneficial in certain contexts, do not address the critical need for effective communication and coordination that is essential in many operational scenarios. High-altitude flying, frequent training sessions, and relying solely on personal judgment might not provide the same level of situational awareness and safety assurance as proper communication with ground personnel.
