  • PI Yizhou Jiang

    CO-I Leitao Chen

    CO-I Yanbing Chen

  • ​This study aimed to fabricate composite materials, i.e. continuous carbon fibers reinforced thermoset composites (CCFRTC), in a way that makes heat transfer predictable, enabling effective control measures. The ability to control thermal transfer through 3D-printing can lead to significant improvements in preventing thermal-related accidents.

A Comparison Of Safety Management Systems Training Methods At A Collegiate Flight Training Institution

  • PI Mackenzie Dickson

  • The purpose of this thesis was to compare how two different types of Safety Management Systems (SMS) training affect SMS knowledge in instructors and students in a university flight program. Additionally, the research sought to determine whether a correlation exists between safety knowledge and safety culture perception. An experimental research design was used to study two independent variables, training method and person type, and their effect of SMS knowledge. A non-experimental design was used to study the correlation between safety knowledge and safety culture perception. Research has shown that a safety-training program’s engagement level has an effect on the safety knowledge retained by trainees. This study sought to determine if higher-engagement, live- presentation training is a better approach to SMS training than a computer-based training module currently in use by the university studied. The results of this study can provide the university with useful guidance in constructing its SMS training program, an essential element to an effective SMS. Additionally, this study can demonstrate the importance of safety training in establishing positive perceptions of the university’s safety culture among students and instructors. 

Academic vs. Non-Academic Jobs: Doctorate Recipients' Career Decision and Job Satisfaction in the Areas of Sciences and Engineering

  • PI Dothang Truong

  • Doctorate recipients are known as the primary knowledge producers in society, and hold high-ranking positions in many employment sectors, including education, government, and private industry. As the demand for human workforce with highest degree increases, it is vital to study how doctorate recipients make their career choice and determinants of their work productivity.
Adding Tropical Cyclone Verification Capabilities to the Model Evaluation Tools – Tropical Cyclone (MET-TC) Software

  • PI Daniel Halperin

  • Producing reliable tropical cyclone (TC) genesis forecasts is an operational priority. The National Hurricane Center uses several TC genesis guidance products for their Tropical Weather Outlook. Furthermore, global model output is used in many TC genesis guidance products and is considered an important source of deterministic TC genesis forecast guidance. This project creates a standard framework for verifying deterministic and probabilistic TC genesis forecasts using the TC-Gen tool in the Model Evaluation Tools software package.

Air Traffic Controllers’ Occupational Stress and Performance in the Future Air Traffic Management

  • PI Hui Wang

    CO-I Edward Mummert

  • As demand for unmanned aerial vehicle (UAV) operations increases, it is vital to understand its effects on air traffic controllers and the safety of the national airspace system. This study’s primary purpose is to determine how UAVs that operate in controlled airspace would influence air traffic controllers’ occupational stress and performance. In a within-subject experimental research design, 24 participants sampled from a university’s undergraduate Air Traffic Management (ATM) program completed three different air traffic control (ATC) scenarios on an en-route ATC simulation system. The degree of UAV automation and control were varied in each scenario. The participants’ stress levels, performance, and workload were measured with both objective and subjective measurements. Within-subjects ANOVA tests showed significant effects on the participants’ stress level, performance, and workload when automated UAVs were present in the scenario. Participants experienced increased workload, the highest level of stress, and carried out the worst performance when with controllable UAVs in the airspace. These findings can inform UAV integration into controlled airspace and future research into UAV automation and control and ATC management. 
Air-Deployed sUAS and StreamSonde Measurements of Turbulence in the High Wind Tropical Cyclone Surface Layer

  • PI Joshua Wadler

  • ​The primary objective of this proposal is to use uncrewed aircraft technology and atmospheric profilers to measure turbulence in the tropical cyclone (TC) boundary layer and to use those measurements to improve NOAA’s operational models.
Airline Pilot Shortage

  • PI Daniel Friedenzohn

  • With colleagues from other academic institutions this project undertook to analyze various pilot supply issues and their impact on the airline industry. The research relied on quantitative data supplied by various databases as well as information provided by the FAA.
An Exploratory Study of General Aviation Visual to Instrument Meteorological Condition Contextual Factors

  • PI James Hartman

    CO-I Mark Friend

  • The purpose of this dissertation was to bridge the existing literature gap of outdated contextual factor (CF) research through examination and determination of current General Aviation (GA) Title 14 Code of Federal Regulations (CFR) Part 91 visual flight rules (VFR)-into-instrument meteorological condition (IMC) contextual factors. Contextual factors are a multifaceted arrangement of pertinent events or occurrences contributing to pilot accidents in weather-related decision-making errors. 
An Investigation of Factors that Influence Passengers’ Intentions to Use Biometric Technologies at Airports

  • PI Kabir Kasim

    CO-I Scott Winter

  • This research investigated the factors that influence passengers’ intentions to choose the use of biometrics over other methods of identification. The current study utilized a quantitative research method via an online survey of 689 persons from Amazon ® Mechanical Turk ® (MTurk) and employed structural equation modeling (SEM) techniques for data analysis. The study utilized the theory of planned behavior (TPB) as the grounded theory, while perceived usefulness and perceived ease of use were included as additional factors that could influence individuals’ intentions to use new technology.

Assessing If Motivation Impacts General Aviation Pilots’ Persistence in Varying Weather Conditions

  • PI Sabrina Woods

    CO-I Scott Winter

  • Continued flight under visual flight rules into instrument meteorological conditions is the predominant cause for fatal accidents by percentage, for general aviation aircraft operations. It is possible that a pilot’s motivation or reason for flying will override other safer, more logical courses of action when a hazard presents itself. The decision appears to stem from a willingness to persist in a course of action despite factors that indicate an alternate and safer course is warranted. This research addresses what is currently presumed about the decision to continue flying under visual flight rules into instrument conditions and marries those ideas with the extensive studies on how theoretically affects the decision-making process.

Autonomous Satellite Recovery

  • CO-I Devonte Grantham

    CO-I Janet Marnane

  • Embry-Riddle Future Space Explorers and Developers (ERFSEDS) will be attending a rocket competition in Utah this coming June, and they will receive extra points for the competition if they have a research project (not built by their club), Inside of their rockets. In collaboration with ERFSEDS, the Society 4 S.P.A.C.E. team would like to send a small satellite attached to a quad-coper as the research project (payload) for ERFSEDS rocket.
Aviation Safety Information Analysis and Sharing for General Aviation
