Which of the following is part of inspecting public protections at an airport?

Inspecting gates and locks is a crucial part of ensuring public protections at an airport because these components directly relate to security and access control. Gates provide entry points for passengers and vehicles, and their locks ensure that unauthorized individuals cannot gain access to restricted areas. By thoroughly inspecting these security features, airport personnel help to maintain safety and prevent potential security breaches.

The other options, while important for overall airport operations, focus on different aspects. Checking runway markings is essential for aviation safety but does not directly relate to public security measures. Reviewing air traffic control procedures is critical for managing flight operations but is more about the movement of aircraft rather than safeguarding the airport environment. Finally, checking weather reporting systems contributes to operational safety and planning but does not directly pertain to the physical security of the airport facilities.
