Aircraft Leading Edge Strakes On Conventional Naca Wings, Anthony Pirone

Discovery Day - Prescott

The prevention of stall on aircraft wings has been a great challenge over the history of airplanes. As the aircraft become more and more complex, it becomes harder to fit high lift devices and leading-edge devices onto high camber, supercritical airfoil aircraft wings. In the fighter jet class of aircraft the obstacle of stall is usually delayed by the implementation of leading-edge root extensions or strakes. Strakes create a tip vortice along the sharp leading edge that transitions over the surface of the wing preventing separation on both the upper and lower surface of the wing allowing the fighter jet …

Evaluating Laanc Compliance And Air Traffic Collision Hazards Posed By Small Unmanned Aircraft Operations In Controlled Airspace, Ryan J. Wallace Ed.D., John M. Robbins Ph.D., James Holliman M.B.A., Jon M. Loffi Edd, Donald S. Metscher D.B.A., Taylor Rogers

National Training Aircraft Symposium (NTAS)

On July 23, 2019, the Federal Aviation Administration (FAA) expanded the Low Altitude Authorization and Notification Capability (LAANC)—the system that processes airspace approvals for sUAS operators in controlled airspace—to include recreational operations. Under LAANC, sUAS operators submit flight request information to one of 14 LAANC Service Suppliers via a mobile or online application. Flight request data is checked against UAS Facility Maps, NOTAMs, and Temporary Flight Restrictions to ensure compliance. Small UAS operators then receive a digital, automated authorization in near-real time. As of May 23, 2019, 591 airports across the United States are included in the LAANC system. Researchers …

Under Pressure: Decision Making In Aircraft Maintenance And The Role Of Gender, Stephanie Douglas Ph.D., Bettina M. Mrusek Ph.D.

National Training Aircraft Symposium (NTAS)

In aircraft maintenance, leaders are under near-constant pressure to maintain airworthiness. Every minute an aircraft cannot fly due to maintenance represents financial waste. Decisions are therefore made in a relatively quick fashion. A leader evaluates the situation, identifies a course of action and then communicates this message to a team of technicians. However, gender influences regarding leaders’ decisions can influence team members’ perceptions of those decisions.

The study will measure decision making methods of leaders in aircraft maintenance and the perceptions of the technicians. It informs how gender influences decision making from both the leader and follower perspective. The expected …

Integrating Aviation Technology, Emergency Services, And Human Resilience: Considerations From Social Scientists, Chelsea A. Lenoble Ph.D., Joel M. Billings Ph.D., Allison A. Kwesell Ph.D., Ray H. Chang Ph.D.

National Training Aircraft Symposium (NTAS)

Unmanned aerial systems (UAS) have a range of applications within the field of disaster response. This presentation offers a novel framework of psychosocial considerations designed to advance UAS and disaster management integration. Social scientists highlight important challenges to the effective integration of three primary entities: UAS, the team of teams that responds to disasters, and populations affected by disasters.

The presentation adopts an emerging theoretical perspective on the intersection between UAS capabilities and disaster phases and extends it by bringing necessary attention to social science issues. Specifically, the framework outlines psychosocial considerations and areas of improvement for preparation (training), response …

Pilot Selection Research Gaps: What We Do And Don't Know About "The Right Stuff", Tomas C. Scott, Meredith Carroll Ph.D.

National Training Aircraft Symposium (NTAS)

Ever since the commencement of high-powered flight, pilot selection has been a crucial process within military, general, and commercial aviation. Through effective pilot selection, individuals with the necessary aptitudes, or "the right stuff" to get through a training program and successfully perform the job, can be chosen. There is a range of different aptitudes that have been shown through research to correlate with effective pilot performance. However, there is currently not a comprehensive understanding of the aptitudes, including both cognitive abilities and psychological attributes, necessary not only for effective pilot performance but also for a successful career as an aviator. …

Exploring Dynamic Delegated Corridors And 4d Required Navigation Performance Trajectory To Enable Uam Aircraft To Integrate Into The Existing Airspace System, Trong Van Nguyen

National Training Aircraft Symposium (NTAS)

Increased traffic congestion on urban road networks has impacted the travel time for commuters in highly populated urban centers. Urban Air Mobility (UAM) is recognized as a system that transports the passenger and air cargo from any location to any destination within a metropolitan area. UAM may offer a solution to the problematic issue of automobile urban surface transportation congestion. However, the predicted significant growth in the demand for integration of UAM operations into the existing airspace system in the next 20 years and beyond may exceed the capacity of current air traffic control (ATC) system resources, particularly the ATC …

Applying And Evaluating A Taxonomy Of Resilient Performance Among Certified Flight Instructors, Kristine M. Kiernan Ph.D., David S. Cross Ph.D., Ed.D., Mark Scharf Ph.D.

National Training Aircraft Symposium (NTAS)

Human error in aviation has been well studied, but the contribution of human performance to system resilience in aviation has not been as well explored. Resilient performance is the ability of a system to make accommodations before, during, and after a disturbance to ensure continued system functioning. Resilient performance is enabled by the ability to anticipate, monitor, learn, and respond. Certified flight instructors will be interviewed using the critical incident debrief method. Interviews will be transcribed and analyzed to explore resilient behavior and evaluate whether the taxonomy of success developed in commercial airline operations is applicable to the flight instruction …

The Effects Of Cultural Factors On Safety In Aviation Focusing On Asian And Western Cultures, Jiyeon Song

National Training Aircraft Symposium (NTAS)

Several aviation accidents from the past, such as the Asiana Flight 214 crash at San Francisco International Airport in 2015, have highlighted possible effects of Korean hierarchy culture on the safety of flight. Previous research conducted primarily with the use of surveys revealed that Asian pilots are less likely to report an unsafe condition out of fear that it will damage their relationships with coworkers and superiors. Western pilots see reporting as dealing with the problem and not a person, thus they feel more open to it. This study looked at student pilots’ ability to recognize and deny an unsafe …

Measuring Fatigue And Sleepiness In Collegiate Aviation Pilots, Julius Keller Ph.D., Flavio A. C. Mendonca Ph.D., Erik Levin, Aaron Teo

National Training Aircraft Symposium (NTAS)

The National Transportation Safety Board has communicated the need to reduce fatigue related accidents through the top ten most wanted list. Additionally, the International Civil Aviation Organization and Federal Aviation Administration have continuously promoted fatigue risk management. Most fatigue related research as well as safety standards in aviation involve air carrier and military operations. However, there has been a recent revival of fatigue related research in collegiate aviation. A recent study found that 85% of collegiate aviation pilots (n = 141) reported fatigue negatively impacted their flight training activities. Results of a qualitative study indicated poor knowledge and behaviors by …
