Which term describes a system's ability to detect problems, intervene, and recover when interventions fail?

• A. Redundancy
• B. Adaptability
• C. Resilience
• D. Robustness

Answer: (C)

Resilience is the ability of a system to detect problems, take corrective actions, and recover to normal operation even when the initial fixes don’t fully solve the issue. In a UAS context, that means the aircraft can sense a fault or disturbance, switch to backup systems or alternate flight modes, continue operating safely, and return to normal performance after the disruption. This explicit focus on detecting issues, intervening, and bouncing back distinguishes resilience from other concepts: redundancy is about having duplicates to prevent failure, adaptability is about adjusting to new conditions, and robustness is about withstanding disturbances without necessarily recovering from a failure.
