Step 1 Identify  stakeholders Step 2 Identify  operational air  traffic or other  services  Step 3 Conduct analysis  to identify  operational  hazards Step 4 Develop the PHL Step 5 Identify effects  of operational  hazards for each  application and  assess their  severity Step 6 Identify existing  controls and  safety  requirements Step 7 Classify  operational  hazards Step 8 Trace  operational  hazards and  effects Step 9 Identify safety  objectives/ requirements  based on  established  severity effects Step 10 Develop OHA Figure C.3: OHA High-Level Process  The tasks required for preparing an OHA 9  are described in  Section 5.2.1 through Section 5.2.9. Identify applicants, approval authorities, and stakeholders needed to establish and demonstrate  compliance with requirements for the air traffic service provision, its use, and any related  CNS/ATM system. The stakeholders should also be SRM panel members, as practicable. Copy the services provided by the solution that were documented in the OSED into the OHA. Identify the operational hazards. Document the analyses undertaken, linking the proposed  improvement and the operational safety of the NAS elements—specifically the detailed, logical,  and analytical connections. For these types of analyses, the most effective method is to “fail”  each of the identified functions and their outputs. This is best done by “failing” the functions  from the developed N 2  diagram or the FFBD, if available. Review the hazards identified and develop a PHL that is concise, clear, and understandable;  this PHL serves as the repository of the initial efforts of the SRM panel to identify all possible  hazards. The PHL is refined and matured over time as the SRM panel validates the identified  9. Refer to the SMS Manual for descriptions of some of the concepts in this section, including a list of analysis tools, the safety order of precedence when identifying controls that mitigate the risk of the hazard, identification of safety requirements, and the determination of a hazard’s severity.
