During flight operations under 14 CFR Part 107, how far must sUAS stay below the base of any clouds?

The requirement for small Unmanned Aircraft Systems (sUAS) to remain below the base of clouds is established to ensure safety and to maintain visual line-of-sight operations for the remote pilot. Under 14 CFR Part 107, sUAS must stay at least 500 feet below the base of any clouds. This distance is critical for ensuring that the pilot can maintain situational awareness and visual separation from manned aircraft, which can operate at higher altitudes. This regulation helps reduce the risk of mid-air collisions and ensures that the sUAS operator has adequate visibility.

Remaining below clouds also aids in compliance with regulations concerning airspace. By maintaining this distance, pilots are more likely to avoid entering airspace that may be restricted or where other aircraft might be operating. Understanding these regulations is crucial for the safety and legality of sUAS operations.
