Tanker Fuel Consolidation: Effects Of Higher Fidelity Modeling On A Resilient Plan, Jason A. Larimore
Theses and Dissertations
The U.S. Air Force (USAF) has selected the KC-46 to begin replacing the aged KC-135 fleet. One of the major differences between the KC-46 and the KC-135 is the KC-46's ability to be refueled. This allows for tanker fuel consolidation, or the refueling of one tanker by another. The effects of this capability on the efficiency of tanker operations must be quantified and included in determining an appropriate substitution ratio between the two aircraft. This ratio will be used to plan the retirement of KC-135s as the KC-46 enters operational fielding. This study utilizes simulation to determine the efficiencies gained …

Improving Knowledge Of C-130 Aircraft Condition: A High Velocity Maintenance Case Study, Marcus R. Mcwilliams
Theses and Dissertations
High Velocity Maintenance (HVM) seems poised to revolutionize the way the Air Force schedules and performs depot-level maintenance on its aircraft. The four tenets of HVM -- Known Condition of the Aircraft, Supportability, Daily Standard Work, and High Burn Rate -- provide the basis for the Air Force's Air Logistics Centers (ALCs) to improve the quality of planning and scheduling that goes into each aircraft's depot maintenance visit. These tenets have been implemented at Warner Robins ALC as part of the C-130 depot maintenance process. While HVM is in active implementation there, much remains to be documented on how the …

Impact Of Self-Reported Biases And Familiarity In A Baggage Screening Context, Scott W. Halwes
Theses and Dissertations
A common assumption is that items that evoke strong emotions are more easily recognized than items that do not evoke strong emotions (Bessette-Symons, 2008). For example, items such as guns or knives may evoke strong emotions within some people, and it may be presumed that these items may be more easily recognized by people that have strong emotions associated with them. If this is true, then perhaps these people would be more apt to locate these items in situations such as baggage screening services that rely on accurate detection of weapons for the public's safety. This study explores this reasoning …

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 …

Disparities In Weather Education Across Professional Flight Baccalaureate Degree Programs, Thomas A. Guinn, Krista M. Rader, Thomas A. Guinn
Publications
The required meteorology coursework for 22 accredited professional flight baccalaureate degree programs was examined and compared. Significant differences were noted in both the number of required meteorology courses as well as the number of required meteorology credit hours. While all programs required at least one three-credit meteorology course, not all programs required an aviation-specific meteorology course. In addition to the required number of meteorology courses and credit hours, topics within the aviation-specific meteorology courses were also examined. The study showed the topics of “flight hazards” and “aviation weather reports and charts” were identified most frequently in course descriptions, followed third …

Electrical & Computer Engineering Faculty Publications
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 …

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 …

Model Individualization For Real-Time Operator Functional State Assessment, Guangfan Zhang, Roger Xu, Wei Wang, Aaron A. Pepe, Feng Li, Jiang Li, Frederick Mckenzie, Tom Schnell, Nick Anderson, Dean Heitkamp
Electrical & Computer Engineering Faculty Publications
Proper assessment of Operator Functional State (OFS) and appropriate workload modulation offer the potential to improve mission effectiveness and aviation safety in both overload and under-load conditions. Although a wide range of research has been devoted to building OFS assessment models, most of the models are based on group statistics and little or no research has been directed towards model individualization, i.e., tuning the group statistics based model for individual pilots. Moreover, little emphasis has been placed on monitoring whether the pilot is disengaged during low workload conditions. The primary focus of this research is to provide a real-time engagement …

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 …

Fast Stochastic Wiener Filter For Super-Resolution Image Restoration With Information Theoretic Visual Quality Assessment, Amr Hussein Yousef, Jiang Li, Mohammad Karim, Mark Allen Neifeld (Ed.), Amit Ashok (Ed.)
Electrical & Computer Engineering Faculty Publications
Super-resolution (SR) refers to reconstructing a single high resolution (HR) image from a set of subsampled, blurred and noisy low resolution (LR) images. The reconstructed image suffers from degradations such as blur, aliasing, photo-detector noise and registration and fusion error. Wiener filter can be used to remove artifacts and enhance the visual quality of the reconstructed images. In this paper, we introduce a new fast stochastic Wiener filter for SR reconstruction and restoration that can be implemented efficiently in the frequency domain. Our derivation depends on the continuous-discrete-continuous (CDC) model that represents most of the degradations encountered during the image-gathering …

Avian Hazard Advisory System (Ahas): An Evaluation Of Ahas Accuracy As A Predictive Tool In Bird Strike Risk Assessment For Civil Aviation, Inger Catherine Oyoko
Theses and Dissertations
The problem of bird strikes began when human aviators made their first ventures in flight and joined birds in an already crowded environment. In the decades following these first flights, the bird strike problem has resulted in numerous fatalities and millions of dollars worth of damaged or destroyed aircraft in both civil and military aviation. The problem has been further exacerbated by the technological leaps in the aviation industry such as the increase in the number of aircraft and engines on an aircraft, the introduction of the jet engine, and also faster, quieter more efficient engine design making aircraft harder …
