The Safety Analysis and Risk Mitigation Process  Section 3  For an example of assessing elements outside the scope of the NAS change in question,  consider the following: A panel of stakeholders and Subject Matter Experts (see  Section 5.1.1)  is tasked with assessing the risk of changing the required longitudinal separation from 3 nautical  miles to 2.5 nautical miles on the final approach course between 10 and 20 nautical miles at  XYZ Airport. The panel does not limit the description of the environment to the final approach  course at XYZ Airport; instead it also considers hazards involved with allowing 2.5 nautical  miles’ separation on the base and downwind legs. By considering these additional legs, the  panel has failed to properly bound its analysis.  30 3.3_SMSM_201509 Originally published September 2015 Uncontrolled copy when downloaded
