The Effects Of Gender And Regional Dialect On Performance In Aviation Communication, Erin E. Mccollum Oct 2004

The Effects Of Gender And Regional Dialect On Performance In Aviation Communication, Erin E. Mccollum

Master's Theses - Daytona Beach

The purpose of this study was to analyze the performance effects of gender and regional dialect on air traffic control statement recall. Sixty-one student volunteers participated in the experiment. Thirty-one participants held a pilot’s license and 30 participants had no flight experience. Each participant listened to one CD with 60 ATC statements each representing a male and female voice and New England, Southern, and General American dialect. Participants were asked to recall exactly what they heard. If the participant could not understand what they heard, they requested a repeat. The participant’s performance was recorded to CD and analyzed. Demographic questionnaires …


The Effect Of Crosswind And Turbulence In Mental Workload And Pilot Tracking Performance, Bruno E. Vivaldi Oct 2004

The Effect Of Crosswind And Turbulence In Mental Workload And Pilot Tracking Performance, Bruno E. Vivaldi

Master's Theses - Daytona Beach

The purpose of this study was to evaluate the effect of crosswind and turbulence on mental workload and pilot tracking performance. Based on previous research, it was believed that as the amount of crosswind and turbulence is increased, mental workload would increase and tracking performance would decrease. The objective was to estimate the impact that crosswind and turbulence, of varying degrees, had on performance and workload. Fifteen full time college student volunteers served as experimental participants in a simulated horizontal and vertical tracking task. Each participant flew twelve instrument approaches, experiencing a different crosswind and turbulence combination during each approach. …

In 2002 the FAA, academic and industry partners established the FAA/Industry Training Standards (FITS) program whose purpose is to modernize General Aviation (GA) pilot training. The FAA recognized the need to modernize training standards for pilots who would use new avionics technology that integrate the GPS (Global Positioning Systems) with the autopilot along with multifunction displays capable of depicting flight path, weather, terrain and traffic information. These avionics and displays are touted as improving safety by enhancing pilot Situational Awareness and reducing pilot workload. The new technology has highlighted the need for programs to train and certify pilots to use …


A New Guidance System For Aircraft Based On Gps, Mukul Mishra May 2004

A New Guidance System For Aircraft Based On Gps, Mukul Mishra

Doctoral Dissertations and Master's Theses

The navigation displays commonly used in aircraft (Course Deviation Indicators), provide only the offset from desired track, leaving the pilot to figure out steering correction necessary to get back on track. This correction, determined by trial and error, adds to the workload, especially in windy conditions. The feasibility of using a new algorithm for providing guidance to the pilots for improved interception and tracking is examined in this thesis. The proposed system employs GPS to calculate the offset from the track as well as the instantaneous ground speed vector, to provide steering information. Thus, precise tracking is possible in real …


Improving The Capability Of Preliminary Aircraft Design Methodology By Incorporating Numerical Methods Into Segments Of A Proven Statistical Method, Igor Lebovic Apr 2004

Improving The Capability Of Preliminary Aircraft Design Methodology By Incorporating Numerical Methods Into Segments Of A Proven Statistical Method, Igor Lebovic

Master's Theses - Daytona Beach

The purpose of this study was to identify any potential limitations of Roskam’s statistical aircraft flight performance estimation method, and to provide processes capable of improving those limitations. This project was conducted in collaboration with Diamond Aircraft Industries, and as any other general aviation manufacturer with limited time, manpower, and financial resources, Diamond wants the new process to be time and cost-effective. Presented in this study is a computational alternative that combines the speed and accuracy of low-order panel methods with the fully-coupled viscous/inviscid interaction method from the ISES code that was developed by Drela and Giles. Its benefit is …


Instrument Pilot Skill Acquisition In The Early Phases Of Flight Training Using An Advanced Cockpit Display System, Erin E. Accettullo Apr 2004

Instrument Pilot Skill Acquisition In The Early Phases Of Flight Training Using An Advanced Cockpit Display System, Erin E. Accettullo

Master's Theses - Daytona Beach

The purpose of this study was to evaluate the learning curve associated with complex flight behavior for both conventional and synthetic vision systems (SVS). The objective was to assess potential differences in learning curves and subjective workload. Workload data across trials indicated a negative linear trend, with a significantly lower level of workload on the synthetic vision display compared to conventional instruments. Levels of performance were significantly higher in the SVS condition, and revealed a quadratic trend, supporting the hypothesis that skill acquisition occurs faster while training with the SVS. These differences in learning and workload curves have implications for …


Final Report: A Comparison Of Three Evaluative Techniques For Validating Maintenance Documentation, Alex Chaparro, Bonnie Rogers, Chris Hambllin, Barbara Chaparro Feb 2004

Final Report: A Comparison Of Three Evaluative Techniques For Validating Maintenance Documentation, Alex Chaparro, Bonnie Rogers, Chris Hambllin, Barbara Chaparro

Publications

Surveys and interviews reveal that general aviation manufacturers rely on user[s] to identify problems in maintenance documentation with corrections typically initiated in response to users-reported problems found in the manual;. This investigation compares techniques that manufacturers can use to improve the quality of the maintenance documentation developed by technical writing groups. The techniques, User Performance and Cognitive Walkthrough, were used to identify problems in aircraft maintenance documentation.


Are Four-Year Universities Better Than Two-Year Colleges At Preparing Students To Pass The Faa Aircraft Mechanic Certification Written Examinations?, Jeffrey Bruce Summey, Marian C. Schultz, James T. Schultz Jan 2004

Are Four-Year Universities Better Than Two-Year Colleges At Preparing Students To Pass The Faa Aircraft Mechanic Certification Written Examinations?, Jeffrey Bruce Summey, Marian C. Schultz, James T. Schultz

Publications

This study evaluates differences between two-year and four-year schools offering a Federal Aviation Administration (FAA) Part 147 aviation maintenance technician program. The actual average test scores were analyzed to determine whether students from four-year university programs were better prepared for the test than students from two-year college or technical school programs. Test scores can be viewed as a direct indication of the quality of the aviation maintenance programs at these schools. The study found that there was no statistically significant difference in the test scores between two-year college and four-year university students taking the FAA examinations. These results support previous …
