How Air Transport Connects The World: A New Metric of Air Connectivity and Its Evolution Between 1990 And 2012
(2015-03-11)Scheduled air transport services connect airports throughout the world and thereby enable interaction on a global scale. By doing so, they spur globalization (Hummels, 2007) as well as social and economic development ... -
Human Factors Flight Testing of an ADS-B Based Traffic Alerting System for General Aviation
(2013-08-06)Mid-air collisions are a concern for general aviation. Current traffic alerting systems have limited usability in the airport environment where a majority of mid-air collisions occur. A Traffic Situation Awareness with ... -
A Human Subject Evaluation of Airport Surface Situational Awareness Using Prototypical Flight Deck Electronic Taxi Chart Displays
(1994-08)The advent of Instrument Landing Systems has allowed aircraft to safely takeoff and land in low visibility conditions. However, the lack of a means by which pilots can safely navigate on the ground in poor visibility ... -
Human-Centered Systems Analysis of Aircraft Separation from Adverse Weather
(2004-06)Adverse weather significantly impacts the safety and efficiency of flight operations. Weather information plays a key role in mitigating the impact of adverse weather on flight operations by supporting air transportation ... -
Human-Centered Systems Analysis Of Mixed Equipage In Oceanic Air Traffic Control
(2004-02)Technical capabilities for improved communication, surveillance, and navigation (CNS) over the oceans are currently available. However, all aircraft operators will not equip simultaneously because of the high costs ... -
Identification of Communication and Coordination Issues in the U. S. Air Traffic Control System
(2001-06)Today’s air traffic control system is approaching the point of saturation, as evidenced by increasing delays across the National Airspace System (NAS). There exists an opportunity to enhance NAS efficiency and reduce ... -
Identification of Important "Party Line" Informational Elements and the Implications for Situational Awareness in the Datalink Environment
(2015-03-18)Air/ground digital datalink communications are an integral component of the FAA's Air Traffic Control (ATC) modernization strategy. With the introduction of datalink into the ATC system, there is concern over the potential ... -
