Effects Of Normobaric Hypoxia On Oculomotor Dynamics Of Aviator Students During A Simulated Flight Task, Carl Wesley Rider, Abby Mccarty, Anna Blackley, Austin Deshner, Josh Engberg, Kaela Ehrlich, Theo Hu, Maja Jankovic, Moroni De Moors, Jared Hornsby, Mitchell Morrison, Brian Walsh

Masters Theses

Hypoxia occurs when the body's tissues are unable to obtain adequate oxygen supply and is the primary environmental factor present when pilots are exposed to increasing altitude levels. Hypoxia leads to impaired vision, cognition, and motor control function, which can negatively affect performance and become deadly if a pilot becomes incapacitated. Thus, objective identification of early-onset hypoxia is critical to increase the time of useful consciousness and prevent physiological episodes. Of the few studies utilizing eye-tracking, there is disagreement and mixed results concerning saccadic eye metrics as a means to measure and detect hypoxia. Therefore, the purpose of this ...

An Exploratory Study Of Us Navy T-45c Simulation Training, Aaron D. Judy Ed.D., Tom Gollery Ed.D.

Journal of Applied Social Science Research and Practice

Flight training is costly and workload intensive. According to a recent Government Accountability Office (GAO) report, the US Navy and US Air Force predict a 25% shortage of fighter pilots by 2023 (GAO, 2018). The military needs empirical research to determine the effectiveness of flight simulation training and whether simulation training can decrease the overall training time for student pilots. The purpose of this study was to compare intermediate and advanced military student pilots’ scores on the T-45C OFT simulator training events and scores on the T-45C aircraft training events in four training domains; the intervention in this study included ...


Evaluating Scenarios That Can Startle And Surprise Pilots, Rahim Daud Agha Apr 2020

Evaluating Scenarios That Can Startle And Surprise Pilots, Rahim Daud Agha

Dissertations and Theses

Startle and surprise on the flight deck is a contributing factor in multiple aviation accidents that have been recognized by multiple aviation safety boards. This study identified the effects startle and surprise had on commercial pilots with single and multiengine ratings. Surprise is defined here as something unexpected (e.g., engine failure), while startle is the associated exaggerated effect of an unexpected condition (e.g., thunder sound). Forty pilots were tested in a basic aviation training device configured to a Cessna 172 (single-engine) and a Baron 58 (multi-engine). Each pilot flew the single- and multiengine aircraft in a scenario that ...

In the PSS 2018, the criteria for success were: ≥90% completions and ≤1 extra training event. In rank order, the following pilots were most successful ...


Aircraft Leading Edge Strakes On Conventional Naca Wings, Anthony Pirone Apr 2020

Aircraft Leading Edge Strakes On Conventional Naca Wings, Anthony Pirone

Discovery Day - Prescott

The prevention of stall on aircraft wings has been a great challenge over the history of airplanes. As the aircraft become more and more complex, it becomes harder to fit high lift devices and leading-edge devices onto high camber, supercritical airfoil aircraft wings. In the fighter jet class of aircraft the obstacle of stall is usually delayed by the implementation of leading-edge root extensions or strakes. Strakes create a tip vortice along the sharp leading edge that transitions over the surface of the wing preventing separation on both the upper and lower surface of the wing allowing the fighter jet ...

Alaska Part 135 Operations: The Need For Additional Regulatory Oversight And Continuous Aircraft Tracking, April A. Larsen Apr 2020

Alaska Part 135 Operations: The Need For Additional Regulatory Oversight And Continuous Aircraft Tracking, April A. Larsen

Student Works

With a focus on Alaska, this research illustrates the lack of regulatory oversight pertaining to Title 14 CFR Part 135 operators, including SMS, training, and equipment requirements. As of January 2020, under the Federal Aviation Administration’s NextGen initiative, all aircraft flying in controlled airspace are required to have an Automatic Dependent Surveillance – Broadcast (ADS– B) system installed and operational. Many Alaskan operators fly in hazardous terrain, and marginal weather, with little to no communication, yet ADS-B is not a requirement as they are in uncontrolled airspace. Alaska also lacks vital aviation infrastructure including adequate instrument approach procedures, weather monitoring ...

Resilient Aircraft Sustainment: Quantifying Resilience Through Asset And Capacity Allocation, Zachary B. Shannon Mar 2020

Resilient Aircraft Sustainment: Quantifying Resilience Through Asset And Capacity Allocation, Zachary B. Shannon

Theses and Dissertations

Decision makers lack a clear, generalizable method to quantify how additional investment in inventory and capacity equates to additional levels of resilience. This research facilitates a deeper understanding of the intricacies and complex interconnectedness of organizational supply chains by monetarily quantifying changes in network resilience. The developed Area under the Curve metric (AUC) is used to quantify the level of demand that each asset allocation can meet during a disruptive event. Due to its applicability across multiple domains, the USAF F-16 repair network in the Pacific theater (PACAF) is modeled utilizing discrete event simulation and used as the illustrating example ...

By order of the Secretary of Defense, all of the US Air Force's F-16 units were tasked to improve their fleet health to a Mission Capability (MC) rate of 80 percent, as part of a Department of Defense-wide push to make its Critical Aviation Platforms, and the units that employ them, more ready and lethal. This study uses historical fleet health and sortie execution data captured from LIMS-EV (Weapon System Viewer, 2020) to create a multiple regression model that quantifies the value of increased fleet health, defined as either MC rate or Aircraft Availability (AA) rate, in terms of ...


Sortie-Based Aircraft Component Demand Rate To Predict Requirements, Thomas R. O'Neal Mar 2020

Sortie-Based Aircraft Component Demand Rate To Predict Requirements, Thomas R. O'Neal

Theses and Dissertations

Weapon System Sustainment (WSS) costs are growing at an increasing rate despite the vast efforts to reduce them. Researchers have attributed much of the cost increase to inaccurate demand forecasts for weapon system spare parts. In 2011, the forecast to sustain all United States Air Force (USAF) aircraft was 19% accurate and WSS costs per year have continuously increased. The purpose of this study is to explore a parsimonious change to aircraft component forecasting to reduce costly forecast error. This study substitutes flying hours with sorties for the purpose of demand forecasting. Many F-16 and B-52 spare parts are evaluated ...
