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
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 …
Integration Of Unmanned Aerial Systems In Class E Airspace: The Effect On Air Traffic Controller Workload, Jeeja S. Vengal
Integration Of Unmanned Aerial Systems In Class E Airspace: The Effect On Air Traffic Controller Workload, Jeeja S. Vengal
Doctoral Dissertations and Master's Theses
As technology rapidly advances and our imagination is no longer fantasy but instead reality, the aviation community needs to concentrate on the harsh truth of airspace safety. In the situation of integrating unmanned aerial systems (UASs) into the National airspace, UASs outside of terminal areas would generally be permitted to fly their preferred routes, and self-separate, with minimal intervention from air traffic control. From an air traffic control perspective, the integration could raise a number of human performance problems including workload extremes and passive-monitoring demands. One fundamental requirement for operation in the National Air Space is to preserve the safety …

An Analysis Of The Effectiveness Of Emergency Locator Transmitters To Reduce Response Time And Locate Wreckage In U.S. General Aviation Accidents, Ajit Jesudoss
Doctoral Dissertations and Master's Theses
Emergency Locator Transmitters (ELT) help search crews to locate aircraft in distress and to rescue survivors. This study analyzed ELT data from U.S. General Aviation accidents during the period 2006 to 2010. This study examined the effectiveness of ELTs in terms of ELT Success Rate (ESR) and False Negative Rate (FNR) based on ELT-Aided. This study found a significant difference between ELT-Operated and ELT-Aided. The ESR was found to be 38.58% whereas the FNR was found to be 61.42 %. The Missing Data Ratio (MDR), where accident reports had no ELT information, was found to be above 95%. Recommendations were …

Analysis Of Airport Security Screening Checkpoints Using Queuing Networks And Discrete Event Simulation: A Theoretical And Empirical Approach, Stephen Louis Dorton
Analysis Of Airport Security Screening Checkpoints Using Queuing Networks And Discrete Event Simulation: A Theoretical And Empirical Approach, Stephen Louis Dorton
Doctoral Dissertations and Master's Theses
This study utilized discrete event simulation (DES) and queuing networks to investigate the effects of baggage volume and alarm rate at the Security Screening Checkpoint (SSCP) of a small origin and destination airport. A Jackson queuing network was considered for a theoretical assessment to SSCP performance. A DES model using Arena version 12 was utilized for an empirical approach. Data was collected from both literature and by manual collection methods. Manual data was collected during the peak operating time of 6am-7am local time at the airport being modeled. The simulation model was verified and validated qualitatively and quantitatively by statistical …
Effects Of Online Training On Aircrew Monitoring Behaviors: A Field Study, Brian A. Potter
Effects Of Online Training On Aircrew Monitoring Behaviors: A Field Study, Brian A. Potter
Doctoral Dissertations and Master's Theses
Data from aircraft accidents and line observation studies indicate that inadequate pilot monitoring is a growing safety concern. In the cockpit environment, pilots who fail to properly manage their workload commit more monitoring errors. Given the lack of training and educational programs available to pilots which emphasize improving their monitoring skills, more research is needed to assess the usefulness of types of training that can be used to improve pilots' monitoring. This research project sets out to determine if the potential exists to enhance pilots' monitoring skills through online training. For this study, 40 military helicopter pilots (participants) were divided …
Nurturing Systems Thinking: Developing A Framework Based On The Human Factors Analysis And Classification System (Hfacs) To Improve Systems Development Processes, Arjun Vijayanarayanan
Nurturing Systems Thinking: Developing A Framework Based On The Human Factors Analysis And Classification System (Hfacs) To Improve Systems Development Processes, Arjun Vijayanarayanan
Doctoral Dissertations and Master's Theses
Large systems engineering projects have an astonishingly high failure rate. The reasons hypothesized for such a high failure rate include the neglect of nonsalient system elements such as social and human or organizational aspects of systems. Social and human factors have long been known to be critical elements of systems that are frequently ignored (e.g., Goguen, 1994). Systems engineering processes can benefit and be improved by effective utilization of a framework that helps developers expand their attention and efforts beyond the salient aspects of the system and the development process. In the aviation field, the Human Factors Analysis and Classification …

This paper presents results of several imbalanced learning techniques applied to operator functional state assessment where the data is highly imbalanced, i.e., some function states (majority classes) have much more training samples than other states (minority classes). Conventional machine learning techniques usually tend to classify all data samples into majority classis and perform poorly for minority classes. In this study, we implemented five imbalanced learning techniques, including random under-sampling, random over-sampling, synthetic minority over-sampling technique (SMOTE), borderline-SMOTE and adaptive synthetic sampling (ADASYN) to solve this problem. Experimental results on a benchmark driving test dataset show that accuracies for minority classes …

An overload condition can lead to high stress for an operator and further cause substantial drops in performance. On the other extreme, in automated systems, an operator may become underloaded; in which case, it is difficult for the operator to maintain sustained attention. When an unexpected event occurs, either internal or external to the automated system, a disengaged operation may neglect, misunderstand, or respond slowly/inappropriately to the situation. In this paper, we discuss a systematic approach monitor for extremes of cognitive workload and engagement in multitasking environments. Inferences of cognitive workload and engagement are based on subjective evaluations, objective performance …

An automatic landing site detection algorithm is proposed for aircraft emergency landing. Emergency landing is an unplanned event in response to emergency situations. If, as is unfortunately usually the case, there is no airstrip or airfield that can be reached by the un-powered aircraft, a crash landing or ditching has to be carried out. Identifying a safe landing site is critical to the survival of passengers and crew. Conventionally, the pilot chooses the landing site visually by looking at the terrain through the cockpit. The success of this vital decision greatly depends on the external environmental factors that can impair …
