Geostationary Operational Environmental Satellite- R Series (Goes-R) 2016, Paige N. Dixon
Geostationary Operational Environmental Satellite- R Series (Goes-R) 2016, Paige N. Dixon
Student Works
This is a report on the first NOAA GOES-R satellite, launched on November 19th, 2016. This report will cover some of the details of the GOES-R project, as well as discuss the collaborations that made the project possible. This document will also detail some of the new satellite’s capabilities including geostationary lightning detection, and space weather monitoring, and will focus on real-world application of such technology. Additionally, this report will list some of the current and projected GOES-R products, and the potential benefits if testing proves successful.

In a follow-up to our previous study, the current work examines the gust-induced “cone of uncertainty” in a small unmanned aerial vehicle’s (UAV) flight trajectory addressed in the context of safety assessments of UAV operations. Such analysis is a critical facet of the integration of unmanned aerial systems (UAS) into the National Airspace System (NAS), particularly in terminal airspace. The paper describes a predictive, robust feedback-loop flight control model that is applicable to various classes of UAVs and unsteady flight-path scenarios. The control design presented in this paper extends previous research results by demonstrating asymptotic (zero steady-state error) altitude regulation …
Quantifying The Effects Of Humidity On Density Altitude Calculations For Professional Aviation Education, Thomas A. Guinn, Randell J. Barry
Quantifying The Effects Of Humidity On Density Altitude Calculations For Professional Aviation Education, Thomas A. Guinn, Randell J. Barry
International Journal of Aviation, Aeronautics, and Aerospace
The effects of humidity on density altitude are quantified in detail and graphically represented as a function of temperature and dew-point temperature for ease of use in professional aviation education. A ten-year climatology of dew-point temperatures for various representative locations throughout the United States is created to provide a basis for comparison and use with the graphical displays. Density altitude is demonstrated to be a function only of dew-point temperature for a given pressure altitude. The absolute errors between density altitude calculations that incorporate humidity to those that do not are combined with linear regression techniques to create a simple …
Predicting General Aviation Pilots’ Weather-Related Performance Through A Scenario-Based Written Assessment, Jessica Cruit
Predicting General Aviation Pilots’ Weather-Related Performance Through A Scenario-Based Written Assessment, Jessica Cruit
Doctoral Dissertations and Master's Theses
Weather-related accidents continue to challenge the general aviation community and with the development of advanced weather technology, GA pilots need additional education and training on how to effectively use these weather products to ensure flight safety. Currently, the literature on aviation weather suggests that there is a gap in both training and assessment strategy for GA pilots. Furthermore, several studies suggest that there needs to be more assessment of weather-related scenario/application questions for the private pilot’s written knowledge exam in order to assess a deeper level of knowledge for weather-related material. The purpose of this study is to design a …
Forecast Verification Of The Current Icing Potential (Cip) To Predict Lightning Hazards At U.S. Spaceports, Robert Edward Haley
Forecast Verification Of The Current Icing Potential (Cip) To Predict Lightning Hazards At U.S. Spaceports, Robert Edward Haley
Doctoral Dissertations and Master's Theses
Government spaceports employ extensive lightning detection networks that may not be available at commercial spaceports. Therefore, the Federal Aviation Administration identified the need for diagnosing the threat of triggered lightning without in-situ measurements. Anecdotal observations of the Aviation Weather Center’s Current Icing Potential (CIP) diagnostic model indicated a potentially high correlation between lightning activity and icing potential. A forecast verification study and supporting representative case studies were conducted to quantify the CIP’s ability to diagnose existing lightning hazards. The study showed that high positive statistical correlations between the CIP and lightning activity do exist, but so do negative correlations. During …
The Tornado That Struck Embry-Riddle Aeronautical University On Christmas Day, 2006: Lessons Learned From A Near-Miss, John M. Lanicci
The Tornado That Struck Embry-Riddle Aeronautical University On Christmas Day, 2006: Lessons Learned From A Near-Miss, John M. Lanicci
Journal of Aviation/Aerospace Education & Research
An F2 tornado that touched down in Daytona Beach on Christmas Day afternoon caused over $50 million of damage to the Embry-Riddle Aeronautical University campus and nearby neighborhoods. The tornado was part of a severe-weather outbreak over Florida, Georgia, and South Carolina that began during the overnight hours of 25 December 2006. Examination of surface and upper-level meteorological charts and vertical soundings on the morning of 25 December showed stability and wind-shear conditions favorable for tornadic thunderstorms over this region. The evolution of the squall line that moved through east-central Florida, and the parent thunderstorm that produced the tornado was …
