NextGen Portfolio - System Safety Management

The System Safety Management portfolio aims to develop and implement the policies, processes, and analytical tools that the FAA and industry will use to ensure the safety and security of the National Airspace System. These resources will be used throughout the FAA to ensure that new capabilities either improve or maintain current safety levels while simultaneously improving capacity and efficiency in the national airspace system. This portfolio currently contains two projects, the Aviation Safety Information Analysis and Sharing (ASIAS) project and the System Safety Management Transformation (SSMT) project. Together these programs will define emerging safety requirements through a series of activities that include research, analysis, demonstrations, and acquisition needs.

Benefits

  • Safety

    Uniform safety standards along with risk and safety management practices should be applied systematically to the air transportation system. In implementing elements of the system, safety needs to be assessed against proper criteria, and according to appropriate and globally standardized safety management processes and practices.
