Simulation For Evaluating The Usability Of Integrated Flight Decks, Troy Ricardo Weeks Dec 2005

Simulation For Evaluating The Usability Of Integrated Flight Decks, Troy Ricardo Weeks

Theses and Dissertations

There is a modern revolution of pilot interface designs as technological advancements force industrial progress in general aviation (GA). Recent accident statistics and safety reports indicate that computerized flight decks in Technically Advanced Aircraft (TAA) present novel safety hazards. Little empirical data have been used to measure the usability of integrated flight decks due to the complexity and time-consuming nature of flight data assessment. The objectives of this thesis are (1) to describe the human factors issues that are induced by the design of the integrated flight deck, (2) to demonstrate the evaluative capabilities of a TAA flight simulator, and …

Comparing F-16 Maintenance Scheduling Philosophies, Konstantinos Iakovidis Jun 2005

Comparing F-16 Maintenance Scheduling Philosophies, Konstantinos Iakovidis

Theses and Dissertations

In the F-16 fighter community it is believed that the flying schedule can make or break a wing's maintenance effort. Nevertheless, there is no published scientific support behind many commonly used maintenance scheduling philosophies. The problem is that a generally accepted overall scheduling philosophy to improve the long term health of the fleet does not exist. The purpose of this research is tri-fold: to identify the most important scheduling philosophies, to identify the most meaningful metrics that capture the long term health of the fleet and maintenance effectiveness, and to compare the various philosophies using the performance measures to help …

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. …

A Study In Drag Reduction Of Close Formation Flight Accounting For Flight Control Trim Positions And Dissimilar Formations, Michael T. Morgan Mar 2005

A Study In Drag Reduction Of Close Formation Flight Accounting For Flight Control Trim Positions And Dissimilar Formations, Michael T. Morgan

Theses and Dissertations

This thesis further defines the position of greatest fuel savings benefit for the trail aircraft flying in a two-ship formation. The HASC95 vortex lattice code was used for the examination. Investigations of a similar formation of F-16 aircraft and a dissimilar formation of a lead KC-135 aircraft and a trail F-16 aircraft were conducted. The analyses determined the effects of varying airspeed on the optimal position. In addition, flight control surface deflections were taken into account during the analyses. Both investigations trimmed the aircraft in the yaw and roll axes to determine the optimal savings. The similar analysis was conducted …

An Analysis Into The Effectiveness Of Aircraft Maintenance Under The Combat Wing Structure, Derrick R. Barthol Mar 2005

An Analysis Into The Effectiveness Of Aircraft Maintenance Under The Combat Wing Structure, Derrick R. Barthol

Theses and Dissertations

Organizational structure builds the foundation from which organizations operate. To gain full potential of structural efficiencies in the current operating environment, public and private firms are continually modifying their organizational structure. The U.S. Air Force is no different and underwent its most recent reorganization in the fall of 2002 replacing the post-Gulf War format of the previous decade. Air Force leadership needs to understand how well the current structure is performing at achieving its intended objectives. This research investigates the effectiveness of the recent change to Air Force organizational structure on aircraft maintenance performance through an analysis of aircraft maintenance …

Evaluating Management Strategies For Automated Test Systems/Equipment (Ats/E): An F-15 Case Study, Jeremy A. Howe Mar 2005

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 …

Estimating Resource Requirements To Support Multi-Echelon F-15e Deployments, David R. Maxwell Mar 2005

Estimating Resource Requirements To Support Multi-Echelon F-15e Deployments, David R. Maxwell

Theses and Dissertations

Since the end of the Cold War, the United States has become focused on developing the capability to rapidly respond to emerging crises. Strategic and operation planning play key roles in order to effectively implement this concept. During the planning process, separate courses of action (COAs) are developed. These COAs are evaluated based upon their operational effect, resource availability, nuclear and transportation feasibility. Currently, transportation feasibility assessments are based on the resources contained within a full Unit Type Code (UTC). Some COAs are eliminated based on these factors. However, most deployments occur at reduced levels. Situational factors, such as the …

Strategic Airlift En Route Analysis And Considerations To Support The Global War On Terrorism, Michael C. Sere Mar 2005

Strategic Airlift En Route Analysis And Considerations To Support The Global War On Terrorism, Michael C. Sere

Theses and Dissertations

The Global War on Terrorism has mandated the need for additional global en route airfields. En route airfields consist of bases that are strategically located at intermediate locations between the Continental United States and the intended theater of operations. These airfields serve as refueling, crew staging, or maintenance stops for strategic airlift aircraft flying transoceanic routes. The focus of this study is to examine concepts to meet this need and to address important aspects that should be considered in devising new en route strategies. Based on various important factors associated with potential en route airfields, a goal programming methodology was …
