However, this is not required for Title 14 Code of Federal Regulations (CFR) Part 135 operations taking place outside of controlled airspace. Part 135 of the Federal Aviation Regulations (FAR) refers to aircraft operating as on-demand or air taxi services. A substantial amount of these operator’s bases, as well as flights, are conducted outside of controlled …

General Aviation Hypoxia And Reporting Statistics, Timothy Holt, Jacqueline Luedtke, Jennah Perry, Michelle Hight, Claire Schindler, Pamela Ward

Journal of Aviation Technology and Engineering

Hypoxia is defined as a lack of oxygen throughout the body, which can be caused by several factors at any altitude. General aviation (GA) pilots may argue that most GA aircraft cannot attain the required altitudes where one might be more affected by hypoxia, but it is exactly that attitude that may makes pilots more susceptible to hypoxia. The impact of this hazardous attitude is even more apparent if one considers that out of the 590,038 certificated pilots in the USA, a little over 30% of them are GA pilots (FAA, 2015). The problem is that unlike airline pilots or …

Examining The Drivers Of C-130j Maintenance Requirements Through Multiple Regression Analysis, Andrew V. Gill

Theses and Dissertations

As a result of increasing system complexity and cost, new aircraft acquisition, upgrade and repair timelines continue to lengthen. As a result, aircraft are kept in service longer than originally intended. Therefore, age-related wear continues to play a large part in determining mission-capable status, and therefore, aircraft availability (AA) rates. Combined with decreasing fleet sizes and manpower resource pools, each aircraft declared not mission capable (NMC) exerts an out-sized influence upon fleet AA rates. This research used multiple regression analysis to identify and quantify the effects of age, Major Command (MAJCOM) and operating location ambient weather on unscheduled not mission …

United States Air Force Applications Of Unmanned Aerial Systems (Uas): A Delphi Study To Examine Current And Future Uas Autonomous Mission Capabilities, Alberto Sigala

Theses and Dissertations

As UAS technology continues to grow and enable increased autonomous capabilities, acquisition and operational decision makers must determine paths to pursue for existing and emerging mission areas. The DoD has published a number of 25-year unmanned systems integration roadmaps (USIR) to describe future capabilities and challenges. However, these roadmaps have lacked distinguishable stakeholder perspectives. Following the USIRs concept, this research focused on UAS autonomy through the lens of UAS subject matter experts (SMEs). We used the Delphi method with SMEs from USAF communities performing day-to-day operations, acquisitions, and research in UAS domains to forecast mission capabilities over the next 20 …

Assessing Artificial Agent Response Time Effects On Human-Agent Teams In Variable Inter-Arrival Time Environments, David J. Canzonetta

Theses and Dissertations

Autonomous systems have gained an expanded presence within the Department of Defense (DoD). Furthermore, the DoD has clearly stated autonomous systems must extend the capabilities of their human operators. Thus, the exploration of strategies for effective pairing of humans and automation supports this vision. Previous research demonstrated that the time at which an automated agent assumes a task for its human teammate, or agent response time (ART), affects human-agent team performance, human engagement, and human workload. However, in this research environment, the time between subsequent tasks appearing to the human-agent team, or inter-arrival time (IAT), remained constant. Variable IAT environments …
