The Procedural Due Process Requirements For No-Fly Lists, Soumya Panda Dec 2005

The Procedural Due Process Requirements For No-Fly Lists, Soumya Panda

The University of New Hampshire Law Review

[Excerpt] “Imagine arriving at the airport and checking in at the ticketing booth. You tell the ticketing agent your name, your flight number, and show the agent your identification. The agent enters the information into the terminal and a look of shock appears on his or her face. While other passengers are waiting behind you, the agent calls for security and mentions in front of other passengers that you are denied from boarding the plane. Now imagine that you are a famous United States senator arriving from a political convention and the ticketing agent tells you that you cannot board …

Effect Of Sound Cue Frequency Filters On Front/Back Localization Performance For Three-Dimensional Verbal And Non-Verbal Warnings, Angelica A. Hernandez Oct 2005

Effect Of Sound Cue Frequency Filters On Front/Back Localization Performance For Three-Dimensional Verbal And Non-Verbal Warnings, Angelica A. Hernandez

Master's Theses - Daytona Beach

In aviation, as technology becomes more advanced and more demands are placed on the human operator, warnings have become an important part of display design. Although warnings have made a significant contribution to safety, problems still plague their design. Recent technological advances have been able to give sounds and warnings a three-dimensional quality (3D). This technology enables a person to perceive sound from any direction around the listener without having the sound physically come from that direction. Three-dimensional sounds have been shown to improve target acquisition and collision avoidance in flight (Oving & Bronkhorst, 1999), and may have other future …

The Influence Of Visibility, Cloud Ceiling, Financial Incentive, And Personality Factors On General Aviation Pilots' Willingness To Take Off Into Marginal Weather, Part I: The Data And Preliminary Conclusions, William Knecht, Howard Harris, Scott Shappell Apr 2005

The Influence Of Visibility, Cloud Ceiling, Financial Incentive, And Personality Factors On General Aviation Pilots' Willingness To Take Off Into Marginal Weather, Part I: The Data And Preliminary Conclusions, William Knecht, Howard Harris, Scott Shappell

Publications

Adverse weather is the leading cause of fatalities in general aviation (GA). In this research, influences of ground visibility, cloud ceiling height, financial incentive, and personality were tested on 60 GA pilots' willingness to take off into simulated adverse weather. Results suggested that pilots do not see "weather" as a monolithic cognitive construct but, rather, as an interaction between its separate factors. This is supported by the finding that the multiplicative statistical effect of visibility and ceiling could better predict takeoff than could the linear effect of either variable considered separately. Also found was a statistical trend toward financial incentive …

Dynamic Modeling And Evaluation Of Recurring Infrastructure Maintenance Budget Determination Methods, Matthew P. Jefson Mar 2005

Dynamic Modeling And Evaluation Of Recurring Infrastructure Maintenance Budget Determination Methods, Matthew P. Jefson

Theses and Dissertations

The focus of this research is using system dynamics modeling to evaluate the impact of missed scheduled maintenance due to budgetary constraints. Missed maintenance cannot be made up and the benefit to the facility's serviceability is lost. The cumulative effect on an entire facility's life span is that it is unable to reach its designed life expectancy. Replacement construction costs are hundreds, thousands, or millions times more than the annual maintenance repair costs. Therefore, Air Force civil engineers must be capable of evaluating maintenance strategies in a dynamic environment to determine the budget strategy's prolonged effect on infrastructure serviceable life. …

Evaluating Management Strategies For Automated Test Systems/Equipment (Ats/E): An F-15 Case Study, Jeremy A. Howe

Theses and Dissertations

The management of United States Air Force ATS/E presents a variety of issues that affect the long-term capability and mission readiness of weapon systems. Traditional procurement processes suggest that individual aircraft platform System Program Offices (SPOs) developed, improved and replaced ATE on an "as-required" basis. Increased obsolescence, however, and a concern for maintaining longer-term viability provided the necessary inertia for a movement towards the procurement and development of consolidated, common test equipment that would support multiple weapon systems. In 1998, the Air Force Chief of Staff directed HQ AFMC to establish a Common Support Equipment office to facilitate the combination …

Extending The Aircraft Availability Model To A Constrained Depot Environment Using Activity-Based Costing And The Theory Of Constraints, Gerardo H. Acosta Voegeli

Theses and Dissertations

The Aircraft Availability Model (AAM) assists managers in the selection of an optimal list of items to repair in order to attain the best aircraft availability rate. The model considers procurement or repair costs for the components as if the costs were unit variable as a price, instead of a repair cost representing a mix of both fixed and variable cost. This research used the AAM in conjunction with Activity Based-Costing (ABC) and The Theory of Constraints (TOC) methodologies to investigate the relationships between price, product mix, Aircraft Availability (AA) and total cost. This approach explicitly recognizes that the Air …
