Portable Electronic Devices On The Flight Deck, Irena Wentzel, John E. Deaton

International Journal of Aviation, Aeronautics, and Aerospace

The emergence of portable electronic devices (PEDs) has provided people with most anything at the touch of a button but has caused many safety-related distractions at the same time. A somewhat addictive reliance on PEDs, mostly smart phones, seems to exist even during times that would prohibit their use. Operation of PEDs during these times has led to some fatal accidents in all areas of transportation. The urgency of this safety issue now means the National Transportation Safety Board (NTSB) studies what role a PED may have played in every new accident investigation. Examining the use of PEDs on the …

A Comparison Of The Strengths And Weaknesses Of Small-Format Aerial Photography Platforms, Jeremy W. Aber, Tyler A. Babb, Douglas E. Campbell, Kevin M. Corns

International Journal of Aviation, Aeronautics, and Aerospace

The demand for small-format aerial photography continues to grow in large part due to the rapid adoption of unmanned aerial vehicles (UAVs). Prior to the explosion of UAV use, this kind of photography was collected using older technologies such as tethered kites and blimps. Due to the increased demand for aerial imagery, this article looks at four platforms commonly used to collect small-format aerial imagery: multi-rotor UAVs, fixed-wing UAVs, kites, and blimps. Practical use considerations are explored, including characteristics of flight and operation, atmospheric and site factors, imaging sensors and costs, and regulatory limitations.

Determining The Location Of Runway Exits Using Airport Surface Detection Equipment, Christopher Bryan Clemmer

Doctoral Dissertations and Master's Theses

Airport surface detection equipment, such as ASDE-X, is used by thirty-five commercially operated airports throughout the United States. ASDE-X is responsible for the safe monitoring of aircraft movements as well as ground support vehicle operating on the airfield. Like most radar-based technologies, ASDE-X can report the position of any aircraft within a one second time interval. This data not only contains the geographic position, but also reports speed, heading, altitude, and aircraft specific characteristics. Using a quantitative approach, this research will use the data reported by ASDE-X to analyze current runway exit locations and develop an improved method of determining …

General Aviation Pilot Acceptance And Adoption Of Electronic Flight Bag Technology, Troy Ernest Techau

Doctoral Dissertations and Master's Theses

This research used an adapted version of the extended Unified Theory of Acceptance and Use of Technology (UTAUT2) to examine electronic flight bag (EFB) acceptance and adoption for general aviation (GA) pilots. EFBs are a common tool in almost all types of aviation and feature many useful capabilities such as the ability to display traffic, weather, and aviation charts. Despite their potential benefits, while some pilots choose to use EFBs in their flight operations, others continue to rely on traditional paper charts and reference materials. Determination of which factors explain differences in pilot acceptance and adoption of EFBs could influence …

Employees Attitudes Toward Safety Risk Management And Safety Performance At U.S. Airports, Umut Oztekin

Theses and Dissertations

Increasing air transportation traffic around the world initiated authorities to take new safety measures into consideration. In 2010, the Federal Aviation Administration (FAA) issued a Notice of Proposed Rulemaking to introduce Safety Management Systems (SMS) to the airport community (FAA, 2016).

Us Airline Stock Market Performance And Change In Investor Behavior Over The Great Recession Of 2008, Rebecca Wood, Jayendra Gokhale

Publications

We study the relationship of West Texas Intermediate (WTI) crude oil returns and the stock market returns with the US airline stocks before, during and after the 2008 financial crisis. We confirm the positive relationship of the airline stock returns with the overall market and the negative relationship with WTI. However, we find that the crisis led to a structural change in this relationship. Our results differ for low-cost airlines which absorb the oil price shock better as compared to legacy airlines. We also find that there is a difference in the relationship between the airline stock returns and WTI …

Implications Of Sensor Inconsistencies And Remote Sensing Error In The Use Of Small Unmanned Aerial Systems For Generation Of Information Products For Agricultural Management, Mac Mckee, Ayman Nassar, Alfonso F. Torres-Rua, Mahyar Aboutalebi, William Kustas

AggieAir Publications

Small, unmanned aerial systems (sUAS) for remote sensing represent a relatively new and growing technology to support decisions for agricultural operations. The size and power limitations of these systems present challenges for the weight, size, and capability of the sensors that can be carried, as well as the geographical coverage that is possible. These factors, together with a lack of standards for sensor technology, its deployment, and data analysis, lead to uncertainties in data quality that can be difficult to detect or characterize. These, in turn, limit comparability between data from different sources and, more importantly, imply limits on the …

Analyzing Operating And Support Costs For Air Force Aircraft, Scott C. Hewitson, Jonathan D. Ritschel, Edward D. White, Gregory Brown

Faculty Publications

Purpose: Recent legislation resulted in an elevation of operating and support (O&S) costs’ relative importance for decision-making in Department of Defense programs. However, a lack of research in O&S hinders a cost analyst’s abilities to provide accurate sustainment estimates. Thus, the purpose of this paper is to investigate when Air Force aircraft O&S costs stabilize and to what degree. Next, a parametric O&S model is developed to predict median O&S costs for use as a new tool for cost analyst practitioners.
Design/Methodology/Approach: Utilizing the Air Force total ownership cost database, 44 programs consisting of 765 observations from 1996 to 2016 …

Unmanned Aerial Vehicle Forensic Investigation Process: Dji Phantom 3 Drone As A Case Study, Alan Roder, Kim-Kwang Raymond Choo, Nhien-A Le-Khac

Annual ADFSL Conference on Digital Forensics, Security and Law

Drones (also known as Unmanned Aerial Vehicles – UAVs) are a potential source of evidence in a digital investigation, partly due to their increasing popularity in our society. However, existing UAV/drone forensics generally rely on conventional digital forensic investigation guidelines such as those of ACPO and NIST, which may not be entirely fit-for-purpose. In this paper, we identify the challenges associated with UAV/drone forensics. We then explore and evaluate existing forensic guidelines, in terms of their effectiveness for UAV/drone forensic investigations. Next, we present our set of guidelines for UAV/drone investigations. Finally, we demonstrate how the proposed guidelines can be …
