Several portions of both the safety review process and flight operations were highlighted as a result of this analysis. Key features were identified and discussed. 74 potential unsafe control actions were found, along with numerous causal scenarios. 141 safety recommendations were made to mitigate potential causes of the UCAs. After comparing this analysis to the existing guidance in AFTCI 91-202 and EAFBI 13-100, nine action items were identified that will enhance the safety of the system as it currently exists.","abstract_html":"As the military moves forward with unmanned aerial vehicles, Edwards AFB must adjust its operations in order to accommodate testing these UASs in all stages of development.
