What is one key rule for flying a sUAS under Part 107 regarding visibility?

For flying a small Unmanned Aircraft System (sUAS) under Part 107, one of the key rules is that the pilot must have a line of sight with the aircraft that is unaided, with the exception of corrective lenses if required. This regulation emphasizes the importance of visual awareness during flight and ensures that the pilot can respond quickly to any situation that may arise.

Having the ability to see the aircraft without relying on magnifying devices ensures that the pilot maintains direct oversight of its operations and can ensure compliance with airspace regulations, other aircraft, obstacles, and safety considerations. This requirement is pivotal for avoiding potential collisions and maintaining situational awareness during flight maneuvers.

Other choices mistakenly suggest the use of assistive devices like binoculars or do not maintain the requirement of direct visual observation of the aircraft, which deviates from the established safety protocols under Part 107.
