What are the four pillars of SMS?

• A. Safety Policy, Safety Risk Management (SRM), Safety Assurance (SA), and Safety Promotion
• B. Safety Policy, Safety Risk Management (SRM), Safety Assurance, and Safety Promotion
• C. Safety Policy, SRM, SA, and Safety Promotion
• D. Safety Policy, SRM, SA, and Security Promotion

Answer: (A)

A Safety Management System (SMS) rests on four pillars that together guide how safety is planned, practiced, and improved in UAS operations. The four components are Safety Policy, Safety Risk Management (SRM), Safety Assurance (SA), and Safety Promotion. Safety Policy sets the tone at the top—establishing the organization’s safety objectives, accountability, and the commitment to a strong safety culture. Safety Risk Management is the systematic process of identifying hazards, assessing the level of risk they pose, and implementing controls to reduce that risk to an acceptable level. Safety Assurance focuses on verifying that safety controls are effective, monitoring performance, conducting audits, and making sure improvements actually take place. Safety Promotion covers training, communication, and activities that encourage a positive safety culture so everyone understands and participates in safety processes. The option that includes Security Promotion is not part of the four SMS pillars, which is why it isn’t the correct choice. The other options convey the same four elements, with slight differences in terminology or punctuation, but the essential set remains Safety Policy, Safety Risk Management, Safety Assurance, and Safety Promotion.
