1  Introduction  The Safety Risk Management Guidance for System Acquisitions (SRMGSA) defines the scope,  purpose, objectives, and required activities of the Federal Aviation Administration (FAA) system  safety effort as it applies to  Safety Risk Management (SRM) for all system acquisitions that  provide Communication, Navigation, and Surveillance; Air Traffic Management; and other  services in the National Airspace System (NAS). 1 The SRMGSA applies to all personnel in the  Air Traffic Organization (ATO) performing SRM analyses/assessments on system acquisitions  and is of interest to the Assistant Administrator of the Office of NextGen (ANG), the Office of  Airports, and other FAA Lines of Business (LOBs).  The SRMGSA embodies and contributes to the spirit of the FAA’s safety culture. A positive  safety culture places a pervasive emphasis on safety and promotes: The SRMGSA provides a framework and further process definition to execute SRM throughout  the entire lifecycle of a system or product. This framework is made formal in the Program  Safety Plan (PSP) developed by the Program Office (PO) and the system developer’s System  Safety Program Plan (SSPP), as contractually required. (Refer to Appendix A for guidance on  developing and implementing PSPs. Refer to Appendix B for a description of the SSPP that the  system developer submits.) The SRMGSA follows systems engineering principles to achieve  the SRM objectives defined in the various FAA publications listed in Section 3.  The purpose of the SRMGSA is to meet the requirements of and implement the policy stated in  FAA Acquisition Management System (AMS), Section 4.12,  National Airspace System Safety  Management System . This section of the AMS requires the application of a Safety  Management System (SMS), referring to the ATO SMS Manual and the SRMGSA as governing  documents with which compliance is mandatory. Therefore, the SRMGSA provides the  guidelines that must be used by the ATO and other organizations when conducting SRM in  acquisitions. In addition, FAA Order 1100.161,  Air Traffic Safety Oversight , focuses the Air  Traffic Safety Oversight Service's (AOV's) efforts on the acquisition and implementation of new  systems to include the modernization/upgrade of legacy NAS systems. Per AOV Safety  Oversight Circular 09-11,  Safety Oversight Standards , new acquisitions are required to follow  the guidance of the AMS and meet the program requirements defined in the SMS Manual and  the SRMGSA. The conduct of SRM maintains or improves the safety of the NAS by identifying the safety risk  associated with making NAS changes and providing that input to decision makers responsible  for managing and mitigating this safety risk. When system 2  safety hazards are identified, the  1. For a complete definition of NAS services, refer to the NAS Requirements Document. This is the source of functional and performance requirements for FAA systems that provide air traffic control services. All operational systems’ capabilities are traceable to specific requirements in the NAS Requirements Document. This document may be found at the NAS Enterprise Architecture Portal. 2.
