Maintenance Operations Degradation Of Airfield Pavement Markings, John C. Jaszkowiak
Theses and Dissertations
Pavement markings are an essential element in the navigational aids subsystem for any airfield. Most airfields still use waterborne paint as the primary marking material, although there are other materials in use on roadways that airfield managers could use to save time and money. An airfield experiences a host of maintenance operations that cause degradation of the pavement markings. Of particular concern are rubber removal operations, sweeping operations, and snowplowing operations. This research focuses on chemical rubber removal operations and sweeping operations. The study evaluates waterborne paint markings and thermoplastic marking strips to determine if these marking materials perform differently …

Background Factors That Affect Pilot Success In Regional Airline Training, Derek Alan Herchko
Doctoral Dissertations and Master's Theses
Following the Colgan Air accident in February 2009, the U.S. Congress and the traveling public called for increased flight experience requirements for pilots of regional airlines. In response, Congress enacted the Airline Safety and Federal Aviation Administration Act of 2010 . This legislation required that regional airline pilots, inclusive of first officers, have an Airline Transport Pilot certificate and a minimum of 1,500 total flight hours. This legislation had a provision that allowed the Federal Aviation Administration to create credit toward flight hours for pilots who had specific academic training courses above normal pilot certification. The Pilot Source Study was …

A Systematic Approach For Real-Time Operator Functional State Assessment, Guangfan Zhang, Wei Wang, Aaron Pepe, Roger Xu, Tom Schnell, Nick Anderson, Dean Heitkamp, Jiang Li, Feng Li, Frederick Mckenzie
Electrical & Computer Engineering Faculty Publications
A task overload condition often leads to high stress for an operator, causing performance degradation and possibly disastrous consequences. Just as dangerous, with automated flight systems, an operator may experience a task underload condition (during the en-route flight phase, for example), becoming easily bored and finding it difficult to maintain sustained attention. When an unexpected event occurs, either internal or external to the automated system, the disengaged operator may neglect, misunderstand, or respond slowly/inappropriately to the situation. In this paper, we discuss an approach for Operator Functional State (OFS) monitoring in a typical aviation environment. A systematic ground truth finding …

In this paper, we present methods to analyze and improve an EEG-based engagement assessment approach, consisting of data preprocessing, feature extraction and engagement state classification. During data preprocessing, spikes, baseline drift and saturation caused by recording devices in EEG signals are identified and eliminated, and a wavelet based method is utilized to remove ocular and muscular artifacts in the EEG recordings. In feature extraction, power spectrum densities with 1 Hz bin are calculated as features, and these features are analyzed using the Fisher score and the one way ANOVA method. In the classification step, a committee classifier is trained based …

Toward GemeinschaftsgefüHl: Exploring Subordinate And Manager Perceptions Of Trust And Perceptions Regarding Behavioral Change Potential, Bobby G. Martin
Publications
In this qualitative, phenomenological study, Maslow‘s Eupsychian theory was used as the guiding framework for exploring the perceptions of trust and the behavioral change potential of subordinates (includes frontline supervisors) and managers (excludes frontline supervisors) within selected aviation maintenance organizations in Arizona. The problem addressed in the study was the growing concern that managers willfully mistreated subordinates, which led to decreased trust, motivation, and productivity. A combined representative sample of 10 maintenance technicians and frontline supervisors was purposively selected from the production lines of a large commercial aviation repair and overhaul station located in Arizona. An additional combined representative sample …

Analysis Of Effects Of Financial Factors On Profitability Of Low-Cost And Legacy Carriers, Nicholas Joseph Kleoppel
Doctoral Dissertations and Master's Theses
Since airline deregulation in 1978, there have been over 180 bankruptcy filings by airlines. Legacy and Low-Cost carriers are unique in how they operate and how they generate revenue; both business models have advantages and disadvantages. However, the Low-Cost carriers have shown increases in revenue and have been growing at increasing rates over the Legacy carriers. This study analyzed financial factors from four airlines in each business model to reveal which financial factors can help determine profitability of an airline. This researcher found significant differences between Legacy and Low-Cost Passenger Revenues, Maintenance Expenses, and Depreciation and Amortization Expenses. Additionally, there …
The Effect Of Shift Turnover Strategy And Time Pressure On Aviation Maintenance Technician Performance,
2011
Embry-Riddle Aeronautical University - Daytona Beach
The Effect Of Shift Turnover Strategy And Time Pressure On Aviation Maintenance Technician Performance, William R. Warren
Doctoral Dissertations and Master's Theses
Aviation maintenance technicians (AMTs) provide the technical and applied knowledge required to maintain airworthiness in aircraft. In commercial aviation, maintenance tasks are performed across multiple shifts. When AMTs share a maintenance task between shifts, the shift turnover strategy used may determine if information is effectively transferred between AMTs. Ineffective shift turnover strategies are a contributing factor in many aviation accidents and incidents. Additionally, time constraints on certain maintenance tasks may cause AMTs to commit error when performing a task. The present study examined the effect of shift turnover strategy (face-to-face or written) and time pressure on error capture, accuracy, and …

An Overview Of The Low-Cost Carrier Model In The Russian Market, Tamilla Curtis, Dawna L. Rhoades
Publications
This study provides an overview of the low-cost carrier (LCC) model in the Russian market. The LCC model seeks to achieve a competitive advantage through the reduction of operating costs, below the traditional airline model. Since Russia is an emerging and developing economy, airlines face a high level of uncertainty. Despite the fact that the Russian aviation market is dominated by a few large carriers, Russian lowcost airlines such as SkyExpress and Avianova have been growing rapidly since starting their operations. While Russian LCCs follow the traditional LCC model, some differences are apparent as a result of the specifics of …

Seven flying robot “fairies” joined human actors in the Texas A&M production of William Shakespeare’s A Midsummer Night’s Dream. The production was a collaboration between the departments of Computer Science and Engineering, Electrical and Computer Engineering, and Theater Arts. The collaboration was motivated by two assertions. First, that the performing arts have principles for creating believable agents that will transfer to robots. Second, the theater is a natural testbed for evaluating the response of untrained human groups (both actors and the audience) to robots interacting with humans in shared spaces, i.e., were believable agents created? The production used two types …

Simulation Modeling And Analysis Of Tnmcs For The B-1 Strategic Bomber, Carl R. Parson
Theses and Dissertations
Simulation provides a method of modeling complex systems which would otherwise be impractical for quantitative experimentation. While other analytic techniques have been used to explore Total Non-Mission Capable [due to] Supply (TNMCS) rates, simulation offers a novel approach to discovering what aspects of the supply chain impact this metric. This research develops a discrete event simulation to investigate factors which affect TNMCS rates for the B-1B by modeling the core processes within the Air Force (AF) supply chain. A notional fleet of 16 aircraft at a single air base (Ellsworth AFB, SD) is modeled based on historical supply and maintenance …
