Due to the plethora of digital devices, ubiquity of the Internet and other networks, and the rapid growth in the adoption of technology, everyone is an information system security manager. Every professional in the aviation and aeronautics industry use computers, mobile devices, tablets, GPS devices, and/or other hardware on a daily basis, as well as go online for a variety of reasons.

Attacks on information have been ongoing since the inception of the industry a hundred years ago, in such forms as intellectual property theft …

A Study Of Human-Machine Interface (Hmi) Learnability For Unmanned Aircraft Systems Command And Control, Tom Haritos Ph.D.

National Training Aircraft Symposium (NTAS)

The operation of sophisticated unmanned aircraft systems (UAS) involves complex interactions between human and machine. Unlike other areas of aviation where technological advancement has flourished to accommodate the modernization of the National Airspace System (NAS), the scientific paradigm of UAS user interface design has received little research attention. This study examined system learnability of an industry standard UAS HMI as minimal usability data exists to support the state-of-the art for innovative command and control user interface designs. Data collected pertained to the three classes of objective usability measures as prescribed by the ISO 9241-11. The three classes included: (1) effectiveness, …

An Alternative Method Of Identification Of A Failed Engine In Twin-Engine Propeller Aircraft, Andrey Babin, Andrew R. Dattel Ph.D.

National Training Aircraft Symposium (NTAS)

Previous research revealed that wrong identification of a failed engine during flight is not an uncommon event in twin-engine propeller aircraft. Most accidents of this type have happened on takeoff when pilot workload was at its highest level. This study was based on the assumption that the “dead leg – dead engine” method was not efficient enough. An alternative method of identification of a failed engine, which involved a visual indicator inside a cockpit, was introduced and tested. Method: Student pilots from Embry-Riddle Aeronautical University who had not obtained multi-engine (MEL) rating were sampled and assigned to two groups – …

Gender Difference In Situation Awareness When Receiving Wayfinding Direction By Landmarks And Headings, Ziyi Dong

National Training Aircraft Symposium (NTAS)

This paper explores how gender differences affect wayfinding strategies and how gender differences and wayfinding preferences can explain variances with situation awareness (SA) in dynamic environments. Four hypotheses were tested: H1: women navigate better from landmarks cues. H2: men navigate better from cardinal directions (i.e., south and northeast). H3: women have better SA than men when given landmarks directions. H4: men show better SA when given cardinal directions. In this study, 38 participants drove a driving simulator twice — once with landmarks and once with headings instructions. These two types of instructions were presented in a random counterbalanced order. Participants …

A Method Of Identification Of A Failed Engine In Twin-Engine Turboprop Aircraft: A Survey, Andrey Babin, Andrew R. Dattel Ph.D.

National Training Aircraft Symposium (NTAS)

Previous research identified that wrong identification of a failed engine during a flight is not an uncommon event in an aircraft cockpit. A number of fatal accidents in the past, including the recent TransAsia Flight 235 accident, resulted from failed engine mis-identification. Most accidents of this type happened on takeoff when pilot workload was at its highest level. A short survey was created and distributed among airline pilots who operate twin-engine turboprop aircraft to gather their opinions regarding the issue. Forty-nine pilots responded to the survey. The average flight experience was more than 6,000 flight hours and almost nine years. …

National Training Aircraft Symposium (NTAS)

Safety culture has been a subject of research for over three decades and is now widely accepted as a critical component of organizational safety programs both domestically and internationally. Through the development of a healthy safety culture, aviation organizations can improve safety processes, reduce mishaps, and mitigate risk more effectively. This is done through the holistic team efforts of an organization’s members and the organization’s leadership. How about aviators who are not part of an organization? Is it possible to identify a personal safety culture defined outside of the traditional organization? And, is it possible to create an instrument allowing …

Effects Of Lighting And Noise On Performance And Situation Awareness In An Air Traffic Control Task, Saralee Pruksaritanon, Andrew Dattel Ph.D., Steven Hampton Ed.D.

National Training Aircraft Symposium (NTAS)

Work environment influences an individual’s performance and situation awareness (SA). This study aims to investigate the effects of lighting and noise levels on performance and situation awareness in an air traffic control (ATC) task. These two variables are important in the domain of ATC because the task requires an individual to receive and process information both visually and auditorily. The results are useful for designing air traffic control rooms, which are set differently among different air navigation service providers. The subjects are 16 students majoring in Air Traffic Management (ATM) at Embry-Riddle Aeronautical University (ERAU) – Daytona Beach, FL. The …

Developing A Robotic Simulator And Video Games For Professional And Public Training, Sushil Louis

INSPIRE-UTC Annual Meetings

Civil engineers are not educated with robotics. They need to be trained on the job with effective tools. The most recent simulation trainer that the PI has built is currently being used by the United States Navy to train surface warfare officers in decision making under stress. In a crowded in-port environment, the crew on a ship’s bridge is trained to probe and identify suspicious boat behavior within the port’s traffic pattern. Officers in charge of the simulation training lesson use software for high-level control of dozens of other ships, boats, and aircrafts that quickly react and adapt to the …

INSPIRE-UTC Annual Meetings

Inspection and preservation of existing transportation infrastructure to extend their service life is an effective way of mitigating the pressure of steadily growing transportation demands on the aging infrastructure. Their current practice, though, represents one of the most costly operations in state departments of transportation.

The INSPIRE University Transportation Center will develop a remotely-controlled robotic platform that helps with these labor-intensive tasks and allows engineers to focus on decision-making processes. An important mission of INSPIRE is to leverage users’ capability of implementing, and interacting with, the robotic platform. Therefore, a long-term plan has been made to create a framework of …

Human Factors Evaluation Of Laptops As A Technical Data Repository In Aircraft Maintenance, Sarah Talley, Christopher Groom

National Training Aircraft Symposium (NTAS)

Digital technology is employed more and more in society for both personal and professional use. Specifically, laptops and tablets are used in diverse environments in a variety of capacities. In the aircraft maintenance environment, many instances of technical data repositories exist in paper form. Retrieval and interaction with these documents can be limiting and introduce human factors that are less than ideal for maintenance operations. The deployment of laptops can alleviate some of those strains and offer a more ergonomic solution for technical data repositories. However, despite the many benefits introduced by technology, laptops may also present ergonomic strains not …

Uas Maintenance: A Critical Component In Maintaining Airworthiness, Bettina M. Mrusek Ph.D., Patti J. Clark Ph.D., Kristy W. Kiernan Ph.D.

National Training Aircraft Symposium (NTAS)

Over the last several decades, the notion of traditional aircraft design has significantly changed. While there are many modern aircraft that resemble earlier models, their components, systems, and overall architecture have evolved, including the introduction of small unmanned aircraft systems. Despite the growing consumer attraction to own and operate these aircraft, the subsequent impact on safety is an area of intense concern. The requirement of an established maintenance program for manned aircraft is rooted in ensuring that all aircraft are deemed safe for flight. Preventive maintenance schedules are based on component reliability data, which minimizes unnecessary maintenance while preventing maintenance-related …

Enhancing Aviation Maintenance Training Using Scenario-Based Education, Raymond Thompson

National Training Aircraft Symposium (NTAS)

Aviation maintenance technician training programs primarily utilize general aviation equipment. Most graduates in the current demand-driven environment are taking positions with air carriers and MRO’s. Industry reports that new technicians required between 2 – 5 years of further training and experience to be considered able to work independently on the shop floor which exacerbates the technician shortage.

Scenario-based education provides graduates with an experience that provides a greater understanding of how large aircraft maintenance is developed and delivered in comparison to small general aviation aircraft. This will allow new hires to become capable of independent work in a shorter time …

Autonomous Wall-Climbing Robots For Inspection And Maintenance Of Concrete Bridges, Jizhong Xiao

INSPIRE-UTC Annual Meetings

Since 2002, the PI’s group has developed four generations of wall-climbing robots for NDE inspection of civil infrastructure. These robots combine the advantages of aerodynamic attraction and suction to achieve a desirable balance of strong adhesion and high mobility. They don’t require perfect sealing and can thus move on smooth and rough surfaces, such as brick, concrete, stucco, wood, glass, and metal. For example, Rise-Rover uses two drive modules to carry their middle compartment with payload up to 450 N. Ground penetrating radar (GPR)-Rover and Mini GPR-Rover are custom designed to carry a GSSI’s GPR antenna for subsurface defect detection …
