Fatigue And Its Management In The Aviation Industry, With Special Reference To Pilots, Rajee Olaganathan, Timothy B. Holt, Jackie Luedtke, Brent D. Bowen

Journal of Aviation Technology and Engineering

Abstract Fatigue is a significant contributing factor that reduces human ability and leads to accidents and threatens the safety of aircraft and human lives. Approximately 70% of fatal accidents that occur in commercial aviation operations are due to human factors. More specifically, crew fatigue contributes to nearly 15 to 20% of the accidents (Akerstedt, 2000). These accidents and incidents are associated with pilot fatigue because of the long duty periods, disruption of circadian rhythms, and inadequate sleep that are common among both commercial and military pilots. Though fatigue is seen in all the disciplines associated with the aviation industry, this ...

This study was designed to determine if pilot school check instructors can be calibrated against a gold standard to perform reliable and accurate evaluations. Calibration followed the principles and theories of andragogy and adult learning and teaching, including emphasis on the cognitive domain of ...

Efficiency Of The United States Navy's Mid-Air Refueling System: Do The Best Pilots In The World Use The Best Equipment?, Austin Westfield

Honors College

The United States Navy has used the Drogue refueling system since the 1950’s. This system, while incredibly effective, has design elements that, if improved upon, could save the Navy millions of dollars per year. For my thesis project within the University of Maine Honors College, I studied the drag characteristics of two models of a refueling apparatus. One model mirrored the current Navy design and the other was based on my sensor array design implemented within my Mechanical Engineering Capstone team project, which was to design, build, and fly a remote-controlled (RC) aircraft that deployed and retracted a towed ...

Air Navigation And Covid-19: Atm Efficiency In Pandemic Crisis, Fabio Lourenco Carneiro Barbosa
