Estimating Airport Operations At General Aviation Airports Using The Faa Npias Airport Categories, Mary E. Johnson, Yue Gu

International Journal of Aviation, Aeronautics, and Aerospace

The number of annual aircraft operations (take-offs and landings) is a significant concern to both airport owners and operators and to governmental agencies because operations data are one of the most important criteria used for determining future investments in airports. However, estimating the number of aircraft operations at non-towered general aviation airports is challenging work due to the lack of counts from air traffic control towers or useful estimates developed using models. Previous work in estimating annual aircraft operations has resulted in models and sampling methods that are imprecise or difficult to use. In 2014, new classification categories of 2,939 …

Utilizing Ground-Based Lidar Measurements To Aid Autonomous Airdrop Systems, Martin Cacan, Edward Scheuermann, Michael Ward, Mark Costello, Nathan Slegers

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Uncertainty in atmospheric winds represents one of the primary sources of landing error in airdrop systems. In this work, a ground-based LIDAR system samples the wind field at discrete points above the target and transmits real-time data to approaching autonomous airdrop systems. In simulation and experimentation, the inclusion of a light detection and ranging (LIDAR) system showed a maximum of 40% improvement over unaided autonomous airdrop systems. Wind information nearest ground level has the largest impact on improving accuracy.

An Examination Of Virtual Environment Training Fidelity On Training Effectiveness, Roberto K. Champney, Kay M. Stanney, Laura Milham, Meredith Carroll, John V. Cohn

Aeronautics Faculty Publications

Live training is a vital component of military training. Unfortunately it can be expensive, resource intensive, of limited accessibility or impossible to achieve due to the risks involved. Virtual environment (VEs) training environments can provide trainees with opportunities to practice key skills and work out performance issues in a more cost effective environment, which may lead to more efficient use of live training time. The current study explored this premise by conducting a transfer of training study that examined the question of whether pre-training in low and/or high fidelity VEs can lead to time savings and improved performance in live …

A Training Effectiveness Evaluation Of Uh-60a/L Simulated Environments: An Interdisciplinary Approach, Martin Goodwin

Electronic Theses and Dissertations

The U.S. military continues to develop and expand its use of simulation-based aviation training. While traditional simulation-based training continues to be a proven training method, game-based simulation has become more sophisticated and may provide viable training options in some applications. The use of game-based simulation with traditional simulation-based training can potentially reduce costs, enhance return on investment, advance training objectives, and inform future training environment designs. Current fiscal limitations are driving the need for more efficient training methods, while operational requirements are dictating training protocols that produce optimum levels of readiness. The gap between fiscal constraints and desired training outcomes …

Global Command And Control For The Future Operating Concept: Implications For Structural Design And Information, Ian M. Slazinik, Benjamin T. Hazen

Faculty Publications

Due to increasing demands on air mobility aircraft, US Transportation Command(USTRANSCOM) has more recently advocated retaining operational control (OPCON)of aircraft it might have transferred to a requesting combatant command in the past. This recent approach mirrors that of similar-type civilian logistics operations that are centrally managed to maximize efficiencies by flowing resources to the point of need without having to navigate through time-consuming sourcing processes. Furthermore, the acceleration of information availability has condensed decision timelines and changed how similar civilian organizations organize and perform, allowing them to react seemingly on a dime to changing market conditions anywhere.4While retaining OPCON might …

Impact Of Us Low Cost Carriers Entrance To The Airline Market In Colombia, South America, Carolina Anderson, Tamilla Curtis, Robert F. Moss, Maryjo O. Smith, Gerson Mey

International Journal of Aviation, Aeronautics, and Aerospace

This study researched the impact of US low cost carriers’ entrance to the airline market in Colombia, South America. The study analyzed the overall market share between Florida and Colombia after U.S. low cost carriers entered the market and finds that the market share for the Colombian flag carrier Avianca and U.S. legacy carrier American Airlines, who used to dominate this market, has decreased; however, the total passenger demand has increased. This increase in passenger demand can be attributed in part to U.S. low cost carriers opening new city pairs and allowing passengers to fly direct to the U.S. from …

Long And Short-Range Air Navigation On Spherical Earth, Nihad E. Daidzic

International Journal of Aviation, Aeronautics, and Aerospace

Global range air navigation implies non-stop flight between any two airports on Earth. Such effort would require airplanes with the operational air range of at least 12,500 NM which is about 40-60% longer than anything existing in commercial air transport today. Air transportation economy requires flying shortest distance, which in the case of spherical Earth are Orthodrome arcs. Rhumb-line navigation has little practical use in long-range flights, but has been presented for historical reasons and for comparison. Database of about 50 major international airports from every corner of the world has been designed and used in testing and route validation. …

Cabin Depressurization As A Hijacking Mitigation Tactic: A Consumer Perceptions Study, Rian Mehta, Stephen Rice, Scott R. Winter, Paul Buza

Publications

The security of a commercial airline flight is the primary concern of all parties involved in the aviation industry. The policies and strategies of dealing with terrorist threats have evolved since the attacks of September 11, 2001. The current policy requires that the cockpit door be locked so that the hijackers have no access to the flight controls. A new method has been discussed whereby the pilots depressurize the cabin so as to eliminate the hijacking threat since all the cabin crew and passengers will be rendered unconscious. While there is a risk of possible negative impact on brain cells …

The Experimental Determination Of The Moment Of Inertia Of A Model Airplane, Michael Koken

Williams Honors College, Honors Research Projects

The objective of this project is to suggest that the moment of inertia for irregular shaped objects can easily be determined experimentally. The objects considered in this experiment were a solid wooden block and a model airplane. To ensure that the method and configuration is sufficient a wooden block with known moments of inertia was first tested, and the results from the experiment were compared to the known and accepted values. For this particular experiment, the periods were determined by timing how long 10 oscillations lasted for 10 different trials, and then taking the average of those 10 trials to …

Increased System Fidelity For Navy Aviation Hypoxia Training, Beth. F. Wheeler Atkinson, Janet Marnane, Daniel L. Immeker, Jonathan Reeh, John Zbranek, Ashwin K. Balasubramanian, David M. Mcettrick, W. Tyler Scheeler

Publications

In 2009, the Naval Aviation Survival Training Program (NASTP) Trainer Management Team (TMT) identified a need for a next-generation normobaric mask-on hypoxia trainer with enhanced capabilities due to the lack of positive air pressure provided by existing capabilities. The lack of a positive pressure-on-demand airflow delivery for current mask-on hypoxia training has been cited as a potential training gap wherein 44% of students experience air hunger (Artino, Folga, & Vacchiano, 2009). As a result, it is unclear whether students are able to recognize more subtle symptoms of hypoxia or if they are masked by air hunger. To address this, researchers …

Actual consumers from the general public were used for each of the five stages of the process, along with input from aviation experts, to …

More Electric Systems Architecture Effect On Business Jet Performance, Kelsey M. Mazur

Doctoral Dissertations and Master's Theses

A more-electric systems architecture, using current state of the art components, is proposed for the business jet Dassault Falcon 2000. A model of the existing aircraft, both of its overall flying characteristics and performance and of its detail systems layout, is created using Pacelab APDc and SysArcc programs. The model is validated with respect to the aircraft published data. Then, another model of the same aircraft is created but, this time, it is for the aircraft with the new architecture and their respective performance is compared. In particular, this results in changes in mission range and the overall system's weight. …
