System Wide Analysis Network for In-Time Safety Monitoring

The System Wide Analysis Network for Safety (SWANS) will deliver up-to-the-minute measurement of hazards and risk events in terminal areas throughout the NAS. Updated with current data every five minutes, SWANS provides timely insight into safety margin trends and detects increases in risk events. These events may indicate changes in airspace risk status and identify possible procedural and other deficiencies. SWANS offers a data processing, distribution, and display infrastructure for adding a wide array of data sources and algorithms to track hazards and measure and predict risk. SWANS contributes directly to the Thrust 5 milestone for Domain-Specific Safety Monitoring and Alerting.SWANS offers near-term benefits to diverse users by delivering in-time monitoring of risk metrics with alerts for emerging trends. SWANS monitors the NAS for medium (days before), short term (hours before), and near real time (minutes before) trends. The SWANS monitoring tool can be delivered directly to airlines and operators for timely use in safety analysis, flight planning, operations monitoring decision making, and flight crew/dispatcher training. FAA safety managers can use SWANS to identify ldquo;hot spotsrdquo; and detect evolving safety trends.SWANS will provide real-time answers to important questions that a robust safety monitoring system should ask:What are the current status of hazard and risk events? How do those conditions compare to normal conditions?Has the number of hazards and risk events increased over the past 15 minutes? 30 minutes?nbsp; Seven days?Are hazards and risk events becoming more or less frequent? Over what time periods?What are the current and recent hot spots around the NAS?By delivering timely answers to these and many other questions, SWANS meets an important FAA and industry requirement for improved tracking of risk events, and contributes to meeting the NASA technical milestone to monitor and assess terminal area safety.
