Safety Analysis Of Automatic Dependent Surveillance – Broadcast (Ads-B) System, Rajee Olaganathan
Safety Analysis Of Automatic Dependent Surveillance – Broadcast (Ads-B) System, Rajee Olaganathan
Publications
ADS-B is one of the significant implementation systems of NextGen, to help pilots and air traffic controllers to create a safer, and more efficient National Airspace System (NAS). First, this research paper will briefly describe the ADS-B system, its design structure, ADS-B In and ADS-B Out systems, its efficiency both in pilot applications and in air traffic control applications, and then discuss about the system safety analysis. The preliminary hazard analysis and fault tree analysis will be done for the identified and selected hazards, and will be briefly discussed. The paper will conclude by providing recommendations to prevent/mitigate the hazards …
Shell Revisited: Cognitive Loading And Effects Of Digitized Flight Deck Automation, Mark D. Miller, Sam Holley
Shell Revisited: Cognitive Loading And Effects Of Digitized Flight Deck Automation, Mark D. Miller, Sam Holley
Publications
Acknowledging the SHELL human factors model, authors examine interfaces among components and assess problems created when the model is aligned with modern digitized flight deck systems. Complacency and overreliance on automated systems are evaluated, and cognitive load and potential for degraded situational awareness are examined. Authors present a SHELL overlay demonstrating where particular digitized functions and operations present challenges to operators and markedly influence effective SHELL interactions in highly complex flight deck systems. Human factors contributing to the Asiana Flight 214 accident are examined and correlates identified with the SHELL analysis. Implications for advanced crew resource management are presented, and …
