Voluntary And Confidential Reporting Systems As A Means Of Reducing The Accident Rate In Shadow 200 Flight Operations, William Lawrence Jagnow May 2007

Voluntary And Confidential Reporting Systems As A Means Of Reducing The Accident Rate In Shadow 200 Flight Operations, William Lawrence Jagnow

Master's Theses - Daytona Beach

Although effective, the United States Army's Shadow 200 Unmanned Aerial Vehicle has suffered an unacceptably high accident rate. Errors committed by operators have significantly contributed to this accident rate. The voluntary and confidential Aviation Safety Reporting System and Aviation Safety Action Program have been successful in identifying and addressing errors committed by air carrier pilots. This study has explored the implementation of voluntary and confidential reporting systems in Shadow 200 flight operations. Mixed methods research combined quantitative survey data and qualitative interview data as a means of determining attitudes relevant to the implementation of such systems. Identified deficiencies included: (a) …

The Effect Of Display Design On Pilot Performance In Controlled Flight Into Terrain Scenarios, Jeremy Charles Smith May 2007

The Effect Of Display Design On Pilot Performance In Controlled Flight Into Terrain Scenarios, Jeremy Charles Smith

Doctoral Dissertations and Master's Theses

New technologies are being developed to prevent the continuing problem of Controlled Flight into Terrain (CFIT) accidents. One such technology, the Synthetic Vision System, seems to hold the solution. While it is readily adapted to the commercial aviation instrument environment, it may not be intuitive enough for the General Aviation private pilot with minimal instrument training. This experiment attempted to examine how pilots of every experience level use and interpret the depiction of synthetic terrain to recognize and avoid potential CFIT situations. The outcome of CFIT was measured against pilot experience and display condition.

Data Mining Methods Applied To Flight Operations Quality Assurance Data: A Comparison To Standard Statistical Methods, Alan J. Stolzer, Carl Halford Jan 2007

Data Mining Methods Applied To Flight Operations Quality Assurance Data: A Comparison To Standard Statistical Methods, Alan J. Stolzer, Carl Halford

Publications

"In a previous study, multiple regression techniques were applied to Flight Operations Quality Assurance-derived data to develop parsimonious model(s) for fuel consumption on the Boeing 757 airplane. The present study examined several data mining algorithms, including neural networks, on the fuel consumption problem and compared them to the multiple regression results obtained earlier. Using regression methods, parsimonious models were obtained that explained approximately 85% of the variation in fuel flow. In general data mining methods were more effective in predicting fuel consumption. Classification and Regression Tree methods reported correlation coefficients of .91 to .92, and General Linear Models and Multilayer …

Developing A Methodology For Assessing Safety Programs Targeting Human Error In Aviation, Scott Shappell, Douglas Wiegmann Nov 2006

Developing A Methodology For Assessing Safety Programs Targeting Human Error In Aviation, Scott Shappell, Douglas Wiegmann

Publications

There is a need to develop an effective methodology for generating comprehensive intervention strategies that map current and proposed safety programs onto well-established types of human error. Two separate studies were conducted using recommendations from NTSB accident investigations and several joint FAA and industry working groups. The goal of the studies was to validate a proposed framework for developing and examining safety initiatives that target human error in aviation. The results suggest five approaches to reducing human factors associated with aviation accidents. When combined with the Human Factors Analysis and Classification System, the resulting Human Factors Intervention Matrix will provide …

Helicopter Flight Operational Quality Assurance (Hfoqa): Development Of Hfoqa Analysis Software, Sergio Teixeira Jun 2006

Helicopter Flight Operational Quality Assurance (Hfoqa): Development Of Hfoqa Analysis Software, Sergio Teixeira

Master's Theses - Daytona Beach

Flight Operational Quality Assurance (FOQA), or Flight Data Monitoring (FDM), has benefited flight safety in both fixed-wing and helicopter operations. The relative youth of FOQA programs has resulted in their minimal application among the helicopter fleets of the world; thus, Helicopter FOQA (HFOQA) has merited consolidation and expansion. This mixed methods design developed HFOQA analysis software via a blend of the qualitative data from helicopter and FOQA experts with quantitative data represented by a sample of de-identified digital flight data from 1,014 helicopter flights. Development of the software emphasized three domains of interest: (a) helicopter flight phases; (b) helicopter operational …

Six Sigma Applied To Flight Operations Quality Assurance: An Exemplar Case Study, Alan J. Stolzer, Han Wu, Carl Halford

School of Graduate Studies - Daytona Beach

“Due to the requirement to maintain and improve the safety record of commercial air transportation in the United States (U.S.) despite increasing traffic, several proactive safety programs have been introduced in recent years. Among these proactive safety programs is a form of Flight Data Monitoring (FDM) known in the U.S. as Flight Operational Quality Assurance (FOQA). FOQA is a program utilizing quantifiable, objective data collected from the air carrier aircraft’s data recording system. The data is then analyzed to identify trends and other indicators of potential safety problems. With few exceptions, FOQA data analysis has been rudimentary, often limited to …

Beneath The Tip Of The Iceberg: A Human Factors Analysis Of General Aviation Accidents In Alaska Versus The Rest Of The United States, Cristy Detwiler, Carla Hackworth, Kali Holcomb, Albert Boquet, Elaine Pfleiderer, Douglas Wiegmann, Scott Shappell

Publications

Historically, general aviation (GA) accidents have been overlooked and their impact under-appreciated when compared with those in the commercial or military sector. Recently however, the Federal Aviation Administration and other governmental and civilian organizations have focused their attention on one piece of this proverbial “iceberg,” that being GA accidents occurring in Alaska. This study examines more than 17,000 GA accidents using the Human Factors Analysis and Classification System. Comparisons of Alaska to the rest of the U.S. (RoUS) included traditional demographic and environmental variables, as well as the human errors committed by aircrews. Overall, categorical differences among unsafe acts (decision …

The Influence Of Visibility, Cloud Ceiling, Financial Incentive, And Personality Factors On General Aviation Pilots' Willingness To Take Off Into Marginal Weather, Part I: The Data And Preliminary Conclusions, William Knecht, Howard Harris, Scott Shappell Apr 2005

The Influence Of Visibility, Cloud Ceiling, Financial Incentive, And Personality Factors On General Aviation Pilots' Willingness To Take Off Into Marginal Weather, Part I: The Data And Preliminary Conclusions, William Knecht, Howard Harris, Scott Shappell

Publications

Adverse weather is the leading cause of fatalities in general aviation (GA). In this research, influences of ground visibility, cloud ceiling height, financial incentive, and personality were tested on 60 GA pilots' willingness to take off into simulated adverse weather. Results suggested that pilots do not see "weather" as a monolithic cognitive construct but, rather, as an interaction between its separate factors. This is supported by the finding that the multiplicative statistical effect of visibility and ceiling could better predict takeoff than could the linear effect of either variable considered separately. Also found was a statistical trend toward financial incentive …

A Human Error Analysis Of General Aviation Controlled Flight Into The Terrain Accidents Occurring Between 1990-1998, Scott A. Shappell, Douglas A. Wiegmann

Publications

Although all aviation accidents are of interest to the Federal Aviation Administration (FAA), perhaps none is more disconcerting than those in which a fully functioning aircraft is inexplicably flown into the ground. Referred to as controlled flight into terrain (CFIT), these accidents continue to be a major safety concern within aviation, in particular general aviation (GA). A previous study as part of the FAA's Safer Skies agenda examined 165 CFIT accidents using root cause analysis and developed 55 interventions to address their causes. While the study represented the work and opinions of several experts in the FAA and industry, the …
