Mitigation is defined as which of the following?

• A. To identify hazards
• B. To lessen the overall risk by decreasing the probability and/or severity of a hazard
• C. To assign responsibilities for the mission
• D. To remove all hazards

Answer: (B)

Mitigation means reducing risk by lowering either the likelihood of a hazard occurring or the severity of its consequences. In UAS operations this is done through controls and practices like thorough preflight checks, proper maintenance, pilot training, fail-safes, and clear procedures to keep overall risk at an acceptable level. Removing all hazards is usually not feasible, and residual risk will remain even after mitigation. Hazard identification is about recognizing what could go wrong, while assigning responsibilities is part of planning and management, not the mitigation step itself.
