A Step Toward Ending Long Airport Security Lines: The Modified Boarding Pass, Joel Lee

Doctoral Dissertations and Master's Theses

Anyone who has traveled by air has most likely experienced long airport security lines. Yet not much is known about its cause because few have considered if passengers have created this problem for themselves. The present study attempts to fill this research gap by suggesting that when passengers are not well-prepared for security screening, they delay the process by making mistakes and not complying with procedures. This lack of preparedness can be attributed to several shortcomings of security signposts. This study proposes the use of a modified boarding pass as an alternative form of signage to help passengers better prepare …

Computational Model For Pedestrian Movement And Infectious Diseases Spread During Air Travel: A Molecular Dynamics-Like Numerical Approach, Pierrot Derjany

Doctoral Dissertations and Master's Theses

There is direct evidence of the transmission of fatal infectious pathogens in large human gatherings. Air transportation is no exception. The mixing of susceptible and infectious individuals in this high-density man-made environment involves pedestrian movement which is generally not taken into account in modeling studies of disease dynamics. This thesis addresses this problem through a multiscale model that combines pedestrian dynamics with stochastic infection spread models. This generic model is applicable to several directly transmitted diseases. Through this multiscale framework, the effectiveness of certain layout and strategies in suppressing the disease spread in highly crowded locations such as airplanes, airports …

Effects Of Musical Ability On Flight Planning, Situational Awareness, And Flight Path Deviations, Andrew P. Henry

Doctoral Dissertations and Master's Theses

Numerous studies have been conducted on music education and the benefits that learning an instrument has on the brain. However, there is little research that connects a pilot’s ability to play an instrument to a pilot’s ability to fly an airplane. When learning an instrument, students learn non-musical abilities, such as executive functions, which may correspond with the skills necessary to be a good pilot. The purpose of this study was to find a relationship between learning a musical instrument and pilot performance, specifically related to flight planning, situational awareness, and flight path deviations. This study was a quasi-experimental design …

Assessing Impacts Of Decentralizing Airpower Command And Control, Allen Goodwin Peck

Doctoral Dissertations and Master's Theses

Centralized control is a fundamental tenet of joint airpower doctrine, yet there are operational situations in which some degree of decentralization may be appropriate. The purpose of this research was to quantitatively assess the impacts of decentralizing the command and control (C2) of airpower under varying operational conditions. The research used the experimental method to test hypotheses regarding decentralization of control. JAEX, a stochastic, attrition-based Blue-versus-Red war gaming model, generated the required data.

The mean difference between JAEX outcomes under centralized control and outcomes under decentralized control constituted the dependent variable for each experiment. The independent variables were the operational …

Benefits Of Additional Runway Crossings On Parallel Runway Operations, Sergio Ezequiel Taleisnik

Doctoral Dissertations and Master's Theses

As the air transportation industry expands, airports face numerous challenges to manage the increasing traffic. Among these problems, runway crossings are a considerable source of ground traffic inefficiency and risk. Building end-around taxiways are the only strategy to avoid crossings, but these are not always feasible, and therefore airport planners must find alternatives. This study consisted of a simulation over an airport that currently requires a vast amount of its arrivals to go through runway crossings in order to reach the apron; the airport simulation software utilized was the Total Airspace and Airport Modeler (TAAM). The process began with a …

A Behavioral Research Model For Small Unmanned Aircraft Systems For Data Gathering Operations, Paul Leonard Myers Iii

Doctoral Dissertations and Master's Theses

According to Hitlin (2017) of the Pew Research Center, only 8% of U.S. citizens own an unmanned aircraft. Additionally, regarding feelings if U.S. citizens saw an unmanned aircraft flying close to where they live, 26% say they would be nervous, 12% feel angry, and 11% are scared. As of March 9, 2018, there were 1,050,328 U.S. small unmanned aircraft system (sUAS) registrations compared to 947,970 November 29, 2017. While sUAS use has increased in the U.S., it has lagged when compared to other items for personal use available to U.S. citizens as 92% own cell phones (Anderson, 2015). This slower …

Building And Integrating An Information Security Trustworthiness Framework For Aviation Systems, Anna Baron Garcia

Doctoral Dissertations and Master's Theses

The aviation infrastructure is broadly composed of aircraft, air traffic control systems, airports and public airfields. Much attention has been given to physical security along the years this industry has been expanding; and now, in the new age of interconnection devices, a growing concern about cybersecurity has risen.

The never-ending improvement of new digital technology has given birth to a new generation of electronic-enabled (e-enabled) aircraft that implement a remarkable amount of new technologies such as IP-enabled networks, COTS (commercial off-the- shelf) components, wireless connectivity, and global positioning systems (GPSs). For example, aircraft manufacturers are building wireless systems to reduce …

Safety Culture, Training, Understanding, Aviation Passion: The Impact On Manual Flight And Operational Performance, Karlene Kassner Petitt

Doctoral Dissertations and Master's Theses

The objective of this study was to understand pilots’ proclivity toward automation usage by identifying the relationship among pilot training, aircraft and systems understanding, safety culture, manual flight behavior, and aviation passion. A survey instrument titled Manual Flight Inventory (MFI) was designed to gather and assess self-reported variables of manual flight behavior, aviation passion, safety culture perception, pilot training, and pilot understanding. Demographic data and automation opinion-based questions were also asked to fully understand pilots’ thoughts on automation, safety culture, policies, procedures, training methodologies and assessment measures, levels of understanding, and study techniques. Exploratory Factor Analysis (EFA) was utilized to …
