Active Network Guidance and Emergency Logic System (ANGEL) Enhancement to in-flight situational awareness

ANGEL technology which will optimize aircrew performance, prevent problems from occurring, and enhance aircrew/aircraft survivability

Software & Information Technology

ImageData from the Naval Safety Center indicates a significant portion of naval aircraft accidents are a result of the degradation in the aircrew’s situational awareness (SA), caused by workload/task saturation. As flight mission roles and human/machine interfaces in the cockpit become more complex, it is anticipated that SA degradation will become a more frequent problem. The Naval Air Warfare Center Weapons Division (NAWCWD) along with the Naval Air Warfare Center, (NAWC), Patuxent River and Boeing Corporation, Seattle has developed and patented a method to provide aircrews with a virtual copilot which integrates and deconflicts data from numerous existing flight systems. The result is real-time safety-critical decision support system, based on information from multiple sources (subsystems, flight systems, crew members, etc).

ANGEL provides three levels of decision support, depending on the situation defined by the integrated data gathered from various information management systems which could include aircraft flight/engine control, aircrew/pilot input, life-support, escape, and collision avoidance subsystems. The first level, Normal flight is essentially unnoticed information management which acts as a buffer to reduce pilot information overload. The second, Problem / Task Saturation involves information management and pilot requested automation, where the pilot has made inappropriate responses or sensors indicate corrective action is needed. The third level of support is Threat to Survival, where emergency cuing and emergency actions are immediately initiated to recover from unsurvivable emergencies.
