For UAV use in crowd control, the aerial perspective must be of a crowd of how many people or more?

• A. 50 people or more
• B. 25 people
• C. 100 people
• D. 10 people

Answer: (A)

The main idea is that using a drone for crowd control is most justified when the crowd is clearly large enough to reveal patterns, density, and flow from an overhead view. From above, you can see how crowded different areas are, how people move through entry and exit points, and where bottlenecks or hotspots form. If the crowd is too small, a drone doesn’t add much value and could raise unnecessary safety or privacy concerns; if the crowd is extremely large, the operation becomes more complex, but the key point for this question is identifying a threshold where the aerial view actually improves situational awareness. The best choice points to a clearly sizable crowd, where the aerial perspective provides meaningful, actionable insight into crowd dynamics.
