Effectiveness Of Tsa Regulations In General Aviation, Samantha Somers

Honors Theses

General aviation (GA) security is one the industry’s most prominent topics. With a direct and indirect economic impact of over a billion dollars annually and many lives at stake, concerns of this matter cannot be ignored or taken lightly. It is difficult to reconcile the opinions of all parties involved to create a safe, affordable way to conveniently fly. The resolution process must begin by examining the sector as a whole, identifying its weaknesses, and determining its current security state. What improvements need to be made by the pilots, corporate flight departments, and general aviation businesses, if any? Are current …

Crew Resource Management Application In Commercial Aviation, Frank Wagener, David C. Ison

Applied Aerospace Science

"The purpose of this study was to extend previous examinations of commercial multi-crew airplane accidents and incidents to evaluate the Crew Resource Management (CRM) application as it relates to error management during the final approach and landing phase of flight. With data obtained from the Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB), a x2 test of independence was performed to examine if there would be a statistically significant relationship between airline management practices and CRM-related causes of accidents/incidents. Between 2002 and 2012, 113 accidents and incidents occurred in the researched segments of flight. In total, 57 …

Integrating Mammalian Hazards With Management At U.S. Civil Airports: A Case Study., Kristin M. Biondi, Jerrold L. Belant, James A. Martin, Travis L. Devault, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife incidents with U.S. civil aircraft cost an estimated $1.4 billion from 1990 to 2010, with mammals 5 times more likely to cause damage than other wildlife. We surveyed 2 general aviation (GA) airports and 6 Part-139 certificated (i.e., certified) airports to assess efficacy of management practices for mammalian species hazardous to aircraft. We obtained information on mammalian species present on airport grounds, types and estimated effectiveness of management techniques, and effort spent on wildlife management. We evaluated management techniques relative to aircraft–wildlife collisions (i.e., incident) frequencies taken from Federal Aviation Administration’s (FAA) National Wildlife Strike Database and species hazard …

Doctoral Dissertations and Master's Theses

In 1972, the first hospital based civilian helicopter emergency medical service (HEMS) in the United States began operations. While the use of helicopters to transport medical casualties started decades previously, St. Anthony Flight for Life represented the start of an industry that would grow rapidly in the years to follow, both in the US and around the world (Flight for Life Colorado, n.d.).

Helicopters provide a valuable contribution to the field of medicine. They are faster than ground-based transportation and able to reach areas considered otherwise remote or impassible. They are highly manoeuvrable, unhindered by traffic, and can land in …

Finite Element Modeling Of Macro Fiber Composite Actuators With Application To Wing De-Icing, Boutros Youssef Azizi

Doctoral Dissertations and Master's Theses

Icing can have a profound impact on aircraft performance during inclement weather conditions. Aircraft icing primarily occurs on the leading edge of wings, tails and engines. The de-icing/anti-icing technologies currently in use are typically bulky, heavy, cover the entire airfoil surface and consume high energy. These drawbacks highlight the need for a de-icing technique that can overcome some or all of the aforementioned problems. Therefore, in this thesis, a proposed de-icing technique is studied in which lightweight Macro Fiber Composite (MFC) actuators are used to break the adhesive bond between the leading edge of a wing and an accumulated ice …

Secure Ads-B: Towards Airborne Communications Security In The Federal Aviation Administration's Next Generation Air Transportation System, Richard C. Agbeyibor

Theses and Dissertations

The U.S. Congress has mandated that all aircraft operating within the National Airspace System, military or civilian, be equipped with ADS-B transponders by the year 2020. The ADS-B aircraft tracking system, part of the Federal Aviation Administration's NextGen overhaul of the Air Transportation System, replaces Radar-based surveillance with a more accurate satellite-based surveillance system. However, the unencrypted nature of ADS-B communication poses an operational security risk to military and law enforcement aircraft conducting sensitive missions. The non-standard format of its message and the legacy communication channels used by its transponders make the ADS-B system unsuitable for traditional encryption mechanisms. FPE, …

Low Speed Re-Fuelling Of Unmanned Aerial Vehicles Using The Drogue System, Ian R. Mcandrew, Elena Navarro

Publications

Unmanned Aerial Vehicles (UAV) are being required to be used in more and more complex situations with larger payloads for extended periods of time. Increasing the expectations and operating ceiling requires increased amounts fuel, that thus limits the potential payloads. This dichotomy has led to the quest for more fuel efficient UAVs; however, when designs are improved then their expectations are increased further. In manned aircraft this can be achieved by in-flight re-fuelling. This research is focused on the process of re-fuelling a UAV at low speeds and the aerodynamics considerations and problems it potentially brings. Practical conclusions to these …

State-Space Representation Of The Unsteady Aerodynamics Of Flapping Flight, Haithem E. Taha, Muhammad R. Hajj, Philip S. Beran

United States Air Force: Publications

A state-space formulation for the aerodynamics of flapping flight is presented. The Duhamel's principle, applied in linear unsteady flows, is extended to non-conventional lift curves to capture the LEV contribution. The aspect ratio effects on the empirical formulae used to predict the static lift due to a stabilized Leading Edge Vortex (LEV) are provided. The unsteady lift due to arbitrary wing motion is generated using the static lift curve. Then, state-space representation for the unsteady lift is derived. The proposed model is validated through a comparison with direct numerical simulations of Navier-Stokes on hovering insects. A comparison with quasi-steady models …

Analysis Of Software Contributions To Military Aviation And Drone Mishaps, Veronica Foreman, Francesca Favaro, Joseph Saleh

Faculty Publications

Software is assuming an increasing role in the aerospace industry, and by the same token it is also playing an increasing role in many recent incidents and accidents of both military and commercial vehicles. To better understand this role, we examine two case studies from the accident database of the Air Force Accident Investigation Board (AIB). We previously illustrated the limitations of the notion of “software failure” and developed, in its stead, the notion of software contribution to adverse events. We show here how specific operational scenarios, generally unconsidered during the software development and testing, trigger those contributions. We provide …

The Effect On Stockholder’S Wealth On Critical Systems Failure And Remedy: The Boeing 787 Case, Jayendra Gokhale, Sunder Raghavan, Victor J. Tremblay

Accounting, Economics, Finance, and Information Sciences - Daytona Beach

In this paper we analyze the effect of Boeing Dreamliner 787’s battery problems on stockholder wealth. Using the event study methodology, we show that the recall in January of 2013 initially caused the company’s cumulative abnormal returns to fall by almost 4% in four trading days after the recall. This was followed by an announcement by two major airlines to ground all of the 787 Dreamliner jets. The FAA also ordered all US airlines to ground their 787s and announced an investigation to review all critical systems of 787s. However within four months of the investigation, FAA approved Boeing’s revisions …
