Use Of Virtual Environments For Simulation Of Accident Investigation, Scott Burgess, Katherine Moran

Aviation / Aeronautics / Aerospace International Research Conference

Aircraft accident investigation requires extensive theoretical and methodological knowledge as well as hands-on application. While there are a handful of training centers that offer crash site reconstructions as training aids, these facilities offer limited static tools that can only be accessed by a minimal number of trainees who have flexible work schedules and access to available budgetary resources for travel, lodging and tuition to attend what is generally not-for-credit hands-on training. The use of a virtual interactive aircraft crash training environment can deliver a virtual crash laboratory to an infinite number of trainees, worldwide, provided computer technology is present. The …

Unmanned Insecurity: The Safety And Privacy Issues Of Unmanned Aircraft Information Assurance, Donna A. Dulo Ph.D.

Aviation / Aeronautics / Aerospace International Research Conference

Information assurance and computer security are foundational paradigms in ground based information systems. However, in the aerial realm of unmanned systems, information security often takes the proverbial back seat to high visibility issues such as safety and privacy. Yet, a secure unmanned aircraft is a basic tenant of safety and privacy in the operational arena. Information assurance and security that are enveloped into an unmanned aircraft protect the systems data, communications, as well as internal operations and permeates not only the aircraft’s systems, but also the system’s interactions with satellites, ground stations, and other aerial entities that share data and …

Danger In The Training Gap, William Korner

Aviation / Aeronautics / Aerospace International Research Conference

Loss of Control in flight has accounted for the largest share of worldwide passenger deaths over the past ten years. Not Controlled Flight into Terrain, not equipment failure or malfunction, not even weather – but Loss of Control, in flight.

And there is a disturbing caveat to this fact: In every one of those accidents over the past ten years where there was a large loss of life – highly trained and legally qualified pilots were at the controls of the aircraft involved. Meaning these accidents should have been preventable – yet they were not, because the pilots in command …

Risk Perception In Aviation Students: Weather Matters, Ric Ferraro Phd, Darci Vandyke, Mary Zander, Krista Anderson, Bethany Kuehlen

International Journal of Aviation, Aeronautics, and Aerospace

Sixty-three aviation major students and 71 non-aviation major students participated in an experiment concerning aviation experience and risk perception (Risk Perception Scale, RPS; Hunter, 2002). Non-aviation students rated three of the RPS risk scenarios (P2Fly, P2Life, P2 Base) as having higher perceived risk than aviation students with the exception of the weather risk scenarios (P2WX). Aviation students perceived the P2WX scenarios to be significantly more risky. These results have implications for how future pilots perceive risk.

Marbles: The Application Of Input-Output Concepts To Safety Management Systems, Tim Brady, A. Stolzer, Anthony Brickhouse, Antonio Cortes, Dan Mccune, Jayathi Raghavan, David Freiwald

Publications

The goal of this research was to apply the economic concept titled Input-Output Analysis to an aviation safety concept titled Safety Management Systems (SMS). Input-Output (IO) is based upon the interrelationships of various components of an economic system and what happens to the system when one or more of those components changes. Since SMS is, by definition, a system with definable components, the research sought to determine if the interrelationships between those components could be determined and quantified. The term ‘‘marbles’’ was used to describe the activities that led to the IO-SMS matrix. Marbles was used as a metaphor for …

Is “Green Dot” Always The Optimum Engines-Out Glide Speed On The Airbus A320 Aircraft?, Kivanc A. Avrenli, Barry J. Dempsey

Journal of Aviation/Aerospace Education & Research

The dual-engine failure checklist of the Airbus A320 states that the optimum airspeed at which the aircraft can be flown is the “green dot” speed when an engine restart is considered impossible. This is because the “green dot” speed maximizes the power-off glide range in wings-level flight. However, it is not known whether the “green dot” speed would still be the optimum airspeed if the power-off landing maneuver primarily consists of sharp turns. The objective of this study is to find out the optimum power-off glide speed for the A320 if the emergency landing maneuver primarily requires sharp turns rather …

Causes And Trends In Maintenance-Related Accidents In Faa-Certified Single Engine Piston Aircraft, Douglas Boyd, A. Stolzer

Publications

The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question.

The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR Part 91. Pearson Chi-Square, Fisher’s Exact Test, and Poisson probability were used in statistical analyses.

The rate of maintenance-related general aviation accidents was 4.3 per million flight hours for the 1989–1993 period and remained unchanged for the most recent period (2009–2013). Maintenance errors …

A Trustworthiness Of Commercial Airline Pilots (T-Cap) Scale For American Consumers, Stephen C. Rice, Rian Mehta, Scott Winter, Korhan Oyman

Publications

The purpose of this study was to create a Trustworthiness of Commercial Airline Pilots (T-CAP) scale that could be used with American participants. Previous research (Rice, Mehta, Steelman, & Winter, 2014) created a similar scale that may be used with Indian participants. However, due to cultural differences, it was necessary to recreate an instrument that could be used with American consumers. In fact, the scale developed by American participants did differ significantly, both in terms of length and items to measure trustworthiness of commercial pilots. Participants were used in the entire process of creating the scale, including item generation and …

Human Behavior During Spaceflight: Evidence From An Analog Environment, Kenny Mikael Arnaldi

Doctoral Dissertations and Master's Theses

Spaceflight offers a multitude of stressors to humans living and working in space, originating from the external space environment and the life-support system. Future space participants may be ordinary people with different medical and psychosocial backgrounds who may not receive the intense spaceflight preparation of astronauts. Consequently, during a mission, a space participant’s mood and behavior could differ from a trained astronaut. This study was an exploratory research project that used an artificial habitat to replicate an orbital environment and the activities performed by humans in space. The study evaluated whether the type of environment affects mood and temperament. Two …

Reliability Of Eyewitness Reports To A Major Aviation Accident, Dave English, Michael Kuzel

International Journal of Aviation, Aeronautics, and Aerospace

There is a paucity of studies on the reliability of eyewitness reports to aviation crashes. We examine witness statements to a widely observed major airline accident to determine if reported accident investigator distrust of details in eyewitness reports is supported by empirical evidence. The extensive archival witness record (N > 300) of a wide-body airliner crash in clear daylight conditions is subjected to statistical analysis to test eyewitness reliability. Even with over 200 witnesses within a three square kilometre (1.6 square mile) area answering a binary observation question, the variance is sometimes high enough to preclude forming statistically significant conclusions …

The purpose of this study was to partially fill the large literature gap in the area of air carrier post-bankruptcy performance through theoretical and practical contributions.

A multilevel exploratory factor analysis was conducted to explore whether the same restructuring areas were found in air carrier specific metrics. All four restructuring areas were found in the factor analysis. …

National Culture: Understanding The Impact Of Cross-Culture On Airline Pilots' Safety Performance In The Middle-East And North Africa (Mena) Region, Shareef Abdulla Kaddas Al-Romaithi

Doctoral Dissertations and Master's Theses

The continuous expansion of Middle Eastern airlines has created a pilot shortage. Since the local pilot population in the Middle East is relatively small, airlines have been relying on foreign pilots to satisfy their operational requirements. Consequently, pilots with diverse cultural perspectives have been operating together. In order to manage this cultural diversity and ensure safe operations, airlines have been applying a number of training and operational strategies such as Crew Resource Management (CRM) with emphasis on adherence to Standard Operating Procedures (SOP). However, CRM was designed and implemented by North Americans as a solution for human factor intricacies among …

The Impact On Educational Technology Of A Fatal Airline Accident: A Case Study, Tim Brady

Publications

The name of the company should read Colgan Air not Cogan Airlines.

"This is a study of how a virtual technology burden was created that impacted the professional pilot college student and various colleges/universities that offer professional pilot degree programs. A cascading set of events began as a result of U.S. congressional reaction to a tragic airline accident. The resulting legislation forced the Federal Aviation Administration to publish new rules for first officer qualifications that were unmindful of the recommendations of professional pilot groups for simulation-based training. Ultimately, this placed a financial burden on both the college/university training curriculum and …

Investigative Techniques Of N-Way Vendor Agreement And Network Analysis Demonstrated With Fake Antivirus, Gary Warner, Mike Nagy, Kyle Jones, Kevin Mitchem

Annual ADFSL Conference on Digital Forensics, Security and Law

Fake AntiVirus (FakeAV) malware experienced a resurgence in the fall of 2013 after falling out of favor after several high profile arrests. FakeAV presents two unique challenges to investigators. First, because each criminal organization running a FakeAV affiliate system regularly alters the appearance of their system, it is sometimes difficult to know whether an incoming criminal complaint or malware sample is related to one ring or the other. Secondly, because FakeAV is delivered in a “Pay Per Install” affiliate model, in addition to the ring-leaders of each major ring, there are many high-volume malware infection rings who are all using …

Work In Progress: An Architecture For Network Path Reconstruction Via Backtraced Ospf Lsdb Synchronization, Raymond A. Hansen

Annual ADFSL Conference on Digital Forensics, Security and Law

There has been extensive work in crime scene reconstruction of physical locations, and much is known in terms of digital forensics of computing devices. However, the network has remained a nebulous combination of entities that are largely ignored during an investigation due to the transient nature of the data that flows through the networks. This paper introduces an architecture for network path reconstruction using the network layer reachability information shared via OSPF Link State Advertisements and the routines and functions of OSPF::rt_sched() as applied to the construction of identical Link State Databases for all routers within an Area.

Application Of Toral Automorphisms To Preserve Confidentiality Principle In Video Live Streaming, Enrique García-Carbajal, Clara Cruz-Ramos, Mariko Nakano-Miyatake

Annual ADFSL Conference on Digital Forensics, Security and Law

Most of the Live Video Systems do not preserve the Confidentiality principle, and send all frames of the video without any protection, allowing an easy “man in the middle” attack. But when it does, it uses cryptographic techniques over streaming data or makes use of secure channel systems. This generates low frame rate and demands many processor resources. In fact native Live Video Streaming demands many resources of all System.

In this paper we propose a technique to preserve confidentiality in Video Live Streaming applying a confusing visual method making use of the Toral Automorphism Spatial Transformation over each frame. …
