Continual Learning Models in Aviation Systems
Get PDFThis paper explores the vital role of continual lifelong learning in advancing machine learning applications within the aviation industry. Through case studies on predictive maintenance and adaptive flight routing, we demonstrate how human-inspired continual learning enables AI systems to adapt incrementally to evolving conditions while preserving critical prior knowledge. This approach addresses fundamental challenges in dynamic, safety-critical aviation environments, promising improved adaptability, safety, and operational efficiency. The discussion highlights benefits, challenges, current progress, and future directions toward building resilient, intelligent aviation AI systems
The Influence of Daylight Saving Time on US Civil Aviation Operations and Safety
Get PDFDaylight Saving Time (DST) involves biannual clock shifts, impacting various sectors, including transportation. While prior research has linked DST transitions to increased workplace injuries and automobile accidents, its effects on aviation safety remain unexplored. This study examines the relationship between DST transitions and aviation accident rates in the continental United States from 1978 to 2024 using data from the National Transportation Safety Board (NTSB). A statistical analysis was conducted to identify variations in accident frequencies surrounding DST transitions. Results indicate no significant increase in aviation accidents following DST changes, contrasting with findings in other industries. This study highlights DST’s impact on aviation safety, by providing insights into its negligible impact on aviation safety. Future research should explore pilot fatigue and operational disruptions associated with DST through qualitative assessments of flight crew experiences
Development and Validation of a Vertiport Usability Scale
Get PDFIntroduction: Urban Air Mobility (UAM), a distinct subset of Advanced Air Mobility (AAM) research, has begun reaching a critical phase in its establishment, particularly with the development and implementation of vertiports. Few studies have assessed consumer perception of vertiports. One particular study focuses on the ideal usage and applicability of vertiports for medical emergencies; however, this current study aims to broaden that perspective by producing a valid scale that other researchers can use. Method: The Vertiport Usability Scale was developed using a multi-stage approach with 1,243 participants. A consensus methodology was employed, whereby participants generated relevant descriptive items, determined which items were most relevant, and provided construct validity to the final scale. Results: The final scale resulted in a single-factor model comprising seven items (convenient, efficient, functional, good location, high quality, usable, and useful). Factor analysis was used to ensure validity, while Cronbach’s Alpha and Guttman’s split-half tests provided evidence of high consistency and reliability. Conclusion: This scale offers a common language for consumers, designers, engineers, and human factors experts to design future vertiports in line with consumer opinions and needs
Effect of a Safety Event on Perceptions of Safety Culture in Collegiate Flight Training
Get PDFA collegiate aviation flight program experienced a series of engine-related issues, leading to the grounding of the entire single-engine fleet. Students’ perceptions of safety culture were analyzed using data from the program’s annual safety culture perception surveys. Data from before and after the safety event showed that five survey items on the safety culture perception survey indicated a positive statistically significant change, while one item showed a negative statistically significant change. Perceptions of lowerclassmen and upperclassmen were also analyzed to determine if there was any variance between the two groups. Results indicated that only one survey item was statistically significant
Variable and equality sign misconceptions in K-12 algebra
Get PDFAlgebra forms the foundation for higher mathematics and is a key component of K–12 education. Most students struggle to conceptualize and apply algebraic principles, which leads to misconceptions that hinder their mathematical progress. This conceptual study reviews algebraic misconceptions about variables and equality signs and presents potential interventions aimed at supporting students in developing accurate conceptual understanding. This conceptual study underscores the need for continued innovative strategies in mathematics education to support learners in achieving algebraic proficiency
