Terminal blast mitigation and public area security concerns are components of which security concept?

• A. In-flight entertainment policy
• B. Aircraft maintenance scheduling
• C. Passenger check-in throughput
• D. Terminal blast mitigation and public area security concerns

Answer: (D)

Airport terminal security and protection of public spaces is the concept being tested. Terminal blast mitigation involves design and measures to reduce the impact of explosions in the terminal, such as barriers, blast-resistant construction, controlled access, surveillance, detection, and coordinated emergency response. Public area security concerns cover safeguarding passenger concourses, gates, and other open, heavily trafficked spaces through access control, monitoring, incident response, and crowd management. Together, these elements reflect a security-focused approach aimed at protecting people and critical terminal infrastructure in open, high-visibility areas. This is the best fit because the other options describe operational or service aspects (like in-flight entertainment policy, maintenance scheduling, or check-in throughput) rather than threat mitigation in terminal public spaces.
