Hazard Avoidance Alerting With Markov Decision Processes
(2004-08)This thesis describes an approach to designing hazard avoidance alerting systems based on a Markov decision process (MDP) model of the alerting process, and shows its benefits over standard design methods. One benefit ... -
The hidden value of air transportation infrastructure
(2003-06-10)Air transportation is a key strategic asset in that it provides access to markets and thereby enables the economic development of nations. Thus, in order to maintain their competitiveness in a global economy, countries ... -
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 ... -
Human Factors Studies of an ADS-B Based Traffic Alerting System for General Aviation
(2012-11-07)Several recent high profile mid-air collisions highlight the fact that mid-air collisions are a concern for general aviation. Current traffic alerting systems have limited usability in the airport environment where a ... -
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 ... -
Impact of Air Transportation on Regional Economic and Social Connectivity in the United States
(2002-10)This paper identifies some of the forces that influence the impact of air transportation on regional connectivity and economic productivity in the United States. In light of recent threats to the financial viability of the ... -
The Impact of Fuel Based Speed Reductions on Controller Conflicts in the National Airspace System
(2012-11-01)Motivated by increasing fuel prices and a higher environmental awareness, a reduction in aircraft cruise speed leads to fuel-burn benefits. However such a change will likely not occur simultaneously fleet wide. Thus, it ... -
The Impact of GPS Velocity Based Flight Control on Flight Instrumentation Architecture
(International Center for Air Transportation, 1999-06)This thesis explores the use of velocity information obtained by a Global Positioning System (GPS) receiver to close the aircraft’s flight control loop. A novel framework to synthesize attitude information from GPS ... -
The Impact of Information Technologies on Air Transportation
(2005-01)The Air Transportation System and several key subsystems including the Aircraft, Airline, and Air Traffic Management are modeled as interacting control loops. The impact of Information Technologies on each of these subsystems ... -
Impact of Operating Context on the Use of Structure in Air Traffic Controller Cognitive Processes
(2003-06-23)This paper investigates the influence of structure on air traffic controllers’ cognitive processes in the TRACON, En Route, and Oceanic environments. Radar data and voice command analyses were conducted to support hypotheses ... -
The Impact of Structure on Cognitive Complexity in Air Traffic Control
(2002-06)Focused interviews with air traffic controllers and traffic management unit personnel, as well as analysis of traffic flow patterns based on Enhanced Traffic Management System (ETMS) data, suggest that controllers rely on ... -
