Which set lists the four core components of an airport Safety Management System (SMS)?

• A. Ground Handling, Aircraft Maintenance, Passenger Screening, and Communications
• B. Security Management, Emergency Operations, Public Relations, and Compliance
• C. Facility Design, Noise Mitigation, Weather Monitoring, and Staffing
• D. Safety Policy, Safety Risk Management, Safety Assurance, and Safety Promotion

Answer: (D)

An airport Safety Management System is built on four integrated components: Safety Policy, Safety Risk Management, Safety Assurance, and Safety Promotion. Safety Policy is the leadership-driven commitment to safety, setting the organization's safety objectives and assigning responsibilities so everyone knows what’s expected. Safety Risk Management is the systematic process for identifying hazards, evaluating the risks they pose, and implementing controls to reduce those risks before they cause harm. Safety Assurance provides ongoing monitoring and verification that the safety controls are effective, using audits, data analysis, and performance indicators to detect issues and drive improvements. Safety Promotion focuses on building a strong safety culture through training, communication, and awareness so that all staff understand their safety roles and contributions.

The other options describe various operational or functional areas that do not constitute the four SMS components. The set listed here matches the ICAO SMS framework, which is why it is the best answer.
