Define "restricted area" in an airport context.

In the context of an airport, a "restricted area" refers specifically to zones that are off-limits to unauthorized individuals. These areas are secured to maintain the safety and security of airport operations, passengers, and aircraft. Access to these zones is typically limited to security-cleared personnel, which may include airport staff, law enforcement, and select contractors who have undergone background checks and security screenings.

Restricted areas are essential for preventing unauthorized individuals from gaining access to sensitive locations, such as runways, taxiways, or areas surrounding aircraft. By controlling access to these spaces, airports can mitigate risks associated with potential security threats, sabotage, and other hazards that could endanger the safety of airport operations and travel.
