The Effects Of Angle-Of-Attack Indication On Aircraft Control In The Event Of An Airspeed Indicator Malfunction, Claas Tido Boesser

Doctoral Dissertations and Master's Theses

Analysis of accident data by the Federal Aviation Administration, the National Transportation Safety Board, and other sources show that loss of control is the leading cause of aircraft accidents. Further evaluation of the data indicates that the majority of loss of control accidents are caused by the aircraft stalling. In response to these data, the Federal Aviation Administration and the General Aviation Joint Steering Committee emphasize the importance of stall and angle-of-attack awareness during flight. The high-profile crash of Air France Flight 447, in which pilots failed to recover from a self-induced stall, reinforced concerns over the need for improved …

A Descriptive Analysis Of Public Comments Submitted In Response To Notice Of Proposed Rules On Air Carrier Pilot Qualification, Amy Chaffee Doolittle

Doctoral Dissertations and Master's Theses

In 2009, the crash of Colgan Flight 3407 in Buffalo, NY raised concerns regarding the adequacy of current pilot qualification standards for entering air carrier operations. In response, the U.S. Congress enacted Public Law 111-216, which requires a pilot to hold an Airline Transport Pilot (ATP) certificate in order to be qualified as a flight crewmember under 14 CFR, part 121, and also allows the Federal Aviation Administration (FAA) to modify the requirements to obtain an ATP certificate. In February 2012, the FAA issued a Notice of Proposed Rulemaking (NPRM) outlining these requirements and calling for public comments on the …

Validation Of New Technology Using Legacy Metrics: Examination Of Surf-Ia Alerting For Runway Incursion Incidents, Robert Edward Joslin

Market Analysis For Small And Mid-Size Commercial Turboprop Aircraft, Vitaly S. Guzhva, Tamilla Curtis, Vladislav Borodulin

Publications

Recent fuel price volatility and growing concerns about the efficiency of regional jets have led to a revival of large turboprop aircraft as efficient passenger carriers on short-haul regional routes. However, the overall market for smaller turboprops is much less defined as it is characterized by a plethora of small commuter and niche operators in addition to regional carriers. Since most small and mid-size turboprop manufacturers have gone bankrupt or discontinued production due to some other reasons, current operators of this aircraft class are left with aging fleets that would need to be replaced by 2020-2030. This paper assesses the …

Relating Air Quality In The Work Environment To Occupational Health Disease, Hussien Awad Alumar

Doctoral Dissertations and Master's Theses

Comprehensive knowledge of the air pollutants effects on the human health generally is a crucial requirement in developing effective policies for reducing such adverse effects related to ambient air pollution. Such knowledge would be essential in helping various affected countries, including the less developed countries (LDCs), to develop effective regulatory frameworks for assessing and managing air quality in the workplaces. Developed and developing countries therefore need to develop effective techniques or strategies focused towards improving the workplace monitoring competence in diverse industrial environments. Such initiatives are essential in reducing or eliminating the industrial pollutants within the workplaces while also helping …

This study adopts simulation to analyze the annual savings by studying the numbers needed, as well as the utilization and operation cost for these supertugs. The results are very encouraging, enabling …

Comparison Of Voice And Text Atc Communications In The Cockpit For Esl Pilots, Shannon Marie Cummings

Doctoral Dissertations and Master's Theses

Throughout the course of any flight, pilots and air traffic control (ATC) are in constant radio communication regarding the position and route of the aircraft. Effective pilot-ATC communication helps to increase safety by increasing the situation awareness of both the pilot and controller. In the current pilot-ATC communication system, auditory messages are sent back and forth between the pilot and controller. The nature of these auditory messages makes them highly susceptible to memory and information processing limitations. This effect is magnified when dealing with pilots who have learned English as a second language (ESL) as people have more difficulty processing …

Estimation Of Real-Time Runway Surface Contamination Using Flight Data Recorder Parameters, Donovan C. Curry

Doctoral Dissertations and Master's Theses

Within this research effort, the development of an analytic process for friction coefficient estimation is presented. Under static equilibrium, the sum of forces and moments acting on the aircraft, in the aircraft body coordinate system, while on the ground at any instant is equal to zero. Under this premise the longitudinal, lateral and normal forces due to landing are calculated along with the individual deceleration components existent when an aircraft comes to a rest during ground roll. In order to validate this hypothesis a six degree of freedom aircraft model had to be created and landing tests had to be …

Of particular interest were strategies experts use to enhance long-term working memory capacity when working with verbal versus aural information. Three air traffic control instructors participated in four complex air traffic control scenarios, two radar scenarios in which information was presented visually and two non-radar scenarios in which information presentation was purely aural. Participants recalled traffic situation information at two points during and at the end of each scenario. Recall data for each scenario type were assessed in terms of evidence about …

Spatial Cognition Differences Between Men And Women In Spatial Cue Environments During Flight Simulation, Heidi Crystal Kim

Doctoral Dissertations and Master's Theses

Ground reference maneuvers are an important component of pilot training. In order to perform these maneuvers, pilots rely on cues from the environment to determine where their aircraft is in relation to objects on the ground. This process requires a high degree of spatial cognition, which refers to the cognitive processes used to orient oneself in space. Two factors that can influence spatial cognition in the context of aviation ground reference maneuvers are the availability of spatial cues and the biological sex of the pilot. Research suggests spatial cues aid in the identification of potentially dangerous objects. In the context …

Reducing Uncertainty In Fatigue Life Limits Of Turbine Engine Alloys, J M. Larson, S K. Jha, C J. Szczepanski, M J. Caton, R John, A H. Rosenberger, D J. Buchanan, P J. Golden, J R. Jira

United States Air Force: Publications

In probabilistic design of materials for fracture-critical components in modern military turbine engines, a typical maximum design target risk (DTR) is 5 X 10^-8 component failures/engine flight hour. This metric underscores the essential role of safety in a design process that simultaneously strives to achieve performance, efficiency, reliability, and affordability throughout the life cycle of the engine. Traditionally, the design and life management approaches for engine materials have typically relied on extensive testing programs to produce large databases of fatigue data, from which statistically based life limits are derived by extrapolation from the mean fatigue behavior. However, we …
