Your CBO's safety guidelines should cover how to handle common emergencies like signal loss, power loss, losing sight of the drone, instrument failure, people or aircraft entering the area, loose parts, battery fires, and sudden bad weather.

Requirement as structured

The FAA recommends that comprehensive safety guidelines address eight specific potential in-flight emergencies, including signal loss, power loss, loss of GPS/sight, instrument failure, unexpected people/aircraft, loose parts, battery fires, and unexpected weather.

Original regulatory text

Loss of navigation (GPS) or loss of sight of the UA. 4. Flight instruments losing performance or displaying incorrect information. 5. Unanticipated people or aircraft entering the area of operation. 6. Parts or attachments on the UA becoming loose or breaking off. 7. Electrical arcing, or battery or component fires. 8.
