2NextGen Task Q: Implementation of NextGen Air Traffic Management system. Airborne Execution of Flow Strategies (AEFS). Modeling, Simulation and Data Analysis
PI Vitaly Guzhva
We work with Metron Aviation, Lockheed Martin, Mosaic ATM and CSSI in development of AEFS concept, designing Modeling and Simulation, collecting data and conducting sensitivity and statistical analyses for concept evaluation.
Airborne Execution of Flow Strategies (AEFS) promotes increased collaboration among National Airspace System (NAS) stakeholders. AEFS recognizes the following current problem: Air Traffic Controllers are aware of the overall air traffic and flight conditions, but lack the capability to collaboratively communicate handling preferences based on flight operators’ business needs, whereas flight operators have limited awareness of Air Traffic Control (ATC) constraints and their potential impacts on flights. By promoting methods to increase collaboration between flight operators and ATC, AEFS targets improvements in Traffic Flow Management (TFM) efficiency, situational awareness among stakeholders, and flexibility in the usage of the NAS.
The FAA conducted research and development of the AEFS concept at the Florida NextGen Test Bed (FTB) at Embry Riddle Aeronautical University (ERAU) in Daytona FL. The research team from ERAU, Metron Aviation, Lockheed Martin, Mosaic ATM, and CSSI demonstrated the AEFS operational scenarios and corresponding use cases through laboratory demonstration as well as Modeling and Simulation (M&S).
The research team conducted two M&S demonstrations: one with Future Concept Team (FCT) members as active participants in the demonstration, and second with FAA stakeholders. Airborne/Airborne; Airborne/Pre-departure; Pre-departure/Airborne; and Pre-departure/pre-departure use cases were recorded and demonstrated to the participants including one airborne/airborne use case with Trial Planning functionality. In all of the use cases, DAL flights originally had default priority 5 that was changed to the highest priority 1 for one of the flights about 10 minutes before that flight would cross the freeze horizon. Based on stakeholder feedback received during the first M&S Demonstration, the FAA demonstrated an additional use case for the second demonstration where one of the flights was instead assigned the lowest priority of 10 to observe the results.
All use cases clearly demonstrated that AEFS would act based on assigned priority reducing sequencing delay for the High Priority Flights (HPF) and increasing it for Low Priority Flights LPF(s). In most cases, more than two flights were involved: a delay from an HPF was distributed among several LPFs, or by increasing delay for an LPF, several higher priority flights were able to decrease their delays. Moreover, the demonstration showed that AEFS successfully altered the arrival sequence based on assigned priorities. Both M&S demonstrations received positive feedback from key stakeholders indicating it was helpful in providing a clearer understanding of the concept.

Resolving Physical Conditions of Diffuse Ionized Gas throughout the Milky Way-Magellanic System
PI Lawrence Haffner
CO-I Edwin Mierkiewicz
We use a dedicated, sensitive spectroscopic facility in Chile, the Wisconsin H-Alpha Mapper (WHAM), to study the physical conditions of the diffuse ionized gas (DIG) in the Milky Way and Magellanic System.
WHAM can reveal emission nearly a 100-million times fainter than the Orion Nebula, making it unsurpassed for collecting high-resolution, optical-line spectra from faint, diffuse sources. Here, we embark on a diverse observational program using multiple optical emission lines with this powerful, remotely-controlled, Fabry-Perot instrument to substantially advance our understanding of interstellar matter and processes that shape it. In previous work, we released the first spectral survey of the Galaxy's DIG with observations of the Balmer-alpha optical emission line of hydrogen. This effort, the WHAM Sky Survey (WHAM-SS), complements neutral gas surveys of the 21-cm radio emission line. The WHAM-SS reveals ionized gas that can be seen in every direction from our location inside the Galaxy and offers a comprehensive view of the distribution and dynamics of the Milky Way's ionized gas. Using different instrument configurations, we are now surveying the southern sky in other emission lines, allowing us to measure physical conditions within the same ionized component.

Information Systems (IS) and Information Security & Assurance (ISA) Curriculum Development and Design: A DACUM Approach.
PI Leila Halawi
PI Wendi Kappers
PI Aaron Glassman
Issues associated with information security are numerous and diverse. Since the majority of organizational actions rely greatly on information and communication technologies, Information Systems (IS) security and Information Security & Assurance (ISA) is now a main concern for firms, governments, institutes, and society as a whole. As a result, a plethora of graduate programs have been created, covering nearly every aspect of IS security. The purpose of this project is to document the findings for using a particularly inventive and extremely efficient technique of job skill analysis known as a DACUM, which stands for “developing a curriculum.” A DACUM begins with an identification of an industry pool that is further reduced to an expert panel, culminating in a daylong workshop to identify new job skill statements and skill needs.
Due to limited DACUM application within the Information Systems (IS) and Information Security & Assurance (ISA) fields of study, DACUM curriculum development milestones and outcomes experienced during the process will be shared to benefit future industry and academic collaborations with regard to curriculum development. Additionally, within the workshop process, the identification of job skill need versus curriculum assessment and activity inclusion is planned and will be documented to produce an end of process expert field survey that expects to support future IS and ISA course development to best support employment opportunities. Furthermore, a discussion of Embry‑Riddle Aeronautical University and its unique relationship with Microsoft will also be included as a possible model for future university-industry partnerships.

Implementing Active Learning Techniques in an Undergraduate Aviation Meteorology Course
PI Daniel Halperin
PI Joseph Keebler
CO-I Robert Eicher
CO-I Thomas Guinn
CO-I Kim Chambers
Student feedback from end-of-course evaluations repeatedly indicated a desire to change the format of the course by de-emphasizing the PowerPoint-based lectures. The goal of the present study was to determine whether including a set of new active-learning techniques in an Aviation Weather course would result in better student understanding (as measured by exam scores) and make the course more engaging (as measured by end-of-course evaluations). During 2018-19, three instructors implemented five different active-learning techniques into their classes (i.e., the experimental group), while two instructors continued to use the unrevised course materials (i.e., the control group). The new active-learning techniques, described below, included daily quizzes, polling questions, flipped classroom sessions, in-class activities, and assertion-evidence-based lectures. All sections used the same assignments and exams, allowing for direct assessment of the effectiveness of the active-learning techniques. Analyses of Variance (ANOVA) tables were used to determine the statistical significance of the differences in exam scores. Indirect assessments in the form of end-of-course evaluations were also examined.

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.
Accurately predicting tropical cyclone (TC) genesis is an important component of providing the public with the information they need to protect life and property in the event of a landfalling storm. The National Hurricane Center (NHC) issues probabilistic forecasts of TC genesis within two and five days in their Tropical Weather Outlook product. There are several guidance products available to the forecasters, many of which rely at least in part on global forecast models. It is important to understand how accurate these guidance products and the global models are at forecasting TC genesis.
This project seeks to create a standard framework for verifying TC genesis forecasts from various sources. This will allow a straightforward comparison between official forecasts, the experimental guidance products, and global model forecasts. These verification capabilities are developed within the existing Model Evaluation Tools (MET) software package from the National Center for Atmospheric Research (NCAR). As such, the user will have considerable flexibility when setting up a verification task. They will also be provided numerous output statistics for deterministic and probabilistic forecasts.

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.
A total of 46 contextual factors were identified and examined from the reviewed research literature. The study examined and determined the presence of the 46 contextual factors, frequencies, and manifestations in the GA VFR-into-IMC Aviation Accident Reports (AARs) archived in the National Transportation Safety Board (NTSB) online safety database. Significant relationships were identified among the contextual factors and pilot age, flight experience, weather, flight conditions, time of day, and certification level using point biserial and phi correlations. Contextual factor significant effects on the crash distance from departure and crash distance from the planned destination were revealed using multiple regression. A qualitative methodology was used on secondary data. Three subject matter experts (SMEs) for the main study analyzed a sample of 85 accidents for the presence of the 46 contextual factors. Raters then reported the presence of the contextual factors and provided opinions on how the contextual factors were manifested. Qualitative analysis revealed the presence of 37 out of 46 contextual factors. Highest frequency factors included number of passengers on board (CF29), accident time of day (CF1), crash distance from the planned destination (CF15), not filing of a flight plan (CF21), and underestimating risk (CF43). Raters described numerous manifestations of the contextual factors including 62% of the accident flights had passengers on board the aircraft (CF29). Quantitative analysis discovered several significantly weak to moderate relationships among pilot age, flight experience, weather, flight conditions, time of day, certification level, and the contextual factors. Several contextual factors had significant effects on the crash distance from departure and crash distance from the planned destination. Findings indicated the contextual factors were extensive in GA accidents. Additional research should focus on all flight domains, including further study of GA Part 91 VFR-into-IMC accidents. It is recommended the GA Part 91 pilot community be trained on the contextual factors assessed.
