Trends Of Non-Fatal Hems Accident-Related Injuries, Richard J. Simonson, Joseph R. Keebler, Alex Chaparro

Publications

We conducted an investigation into non-fatal helicopter emergency medical service accidents from January 26, 1991 to April 26, 2018 via the National Transportation Safety Board aviation accident database. Over this 28-year timeframe 247 accidents results in 251 fatalities and 179 non-fatal injuries. Exploratory analysis of the data indicate that more non-fatal injuries occurred in September compared to any other month during the study timeframe. Exploratory correlational analysis via elastic net logistic regression concluded that no linear relationship of NTSB accident database data provide insights into what factors are correlated with an increased likelihood of non-fatal injuries. Further, no linear relationships ...


Riyadh Neighborhood Residents’ Use And Satisfaction With Urban Green Spaces, Tahar Ledraa, Majed Hallawani, Awad Al-Qahtani 2021 King Saud University, Riyadh

Riyadh Neighborhood Residents’ Use And Satisfaction With Urban Green Spaces, Tahar Ledraa, Majed Hallawani, Awad Al-Qahtani

Emirates Journal for Engineering Research

Neighborhood urban green spaces are indispensable elements for residents’ rest and recreation. They are also of paramount importance to enhance quality of life within neighborhoods. However, these urban green spaces did not receive much research interest, particularly in cities of the developing world. Larger city parks seem to have been the focus of studies. The present study is undertaken under the contention that dissatisfaction with a service is the difference between what is expected from that service and what is really experienced out of it. The gap between expectancy and what is experienced in reality would lead to how satisfied ...


Helipad Detection From Satellite Imagery Using Convolutional Neural Networks, David Specht 2021 Rowan University

Helipad Detection From Satellite Imagery Using Convolutional Neural Networks, David Specht

Theses and Dissertations

Location data about U.S. heliports is often inaccurate or nonexistent in the FAA's databases, which leaves pilots and air ambulance operators with inaccurate information about where to find safe landing zones. In the 2018 FAA Reauthorization Act, Congress required the FAA to collect better information from the helicopter industry under part 157, which covers the construction, alteration, activation and deactivation of airports and heliports. At the same time, there is no requirement to report private helipads to the FAA when constructed or removed, and some public heliports do not have up to date records. This thesis proposes an ...

Fatigue And Its Management In The Aviation Industry, With Special Reference To Pilots, Rajee Olaganathan, Timothy B. Holt, Jackie Luedtke, Brent D. Bowen 2021 Embry-Riddle Aeronautical University

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 ...

Soarnet, Deep Learning Thermal Detection For Free Flight, Jake T. Tallman 2021 California Polytechnic State University, San Luis Obispo

Soarnet, Deep Learning Thermal Detection For Free Flight, Jake T. Tallman

Master's Theses

Thermals are regions of rising hot air formed on the ground through the warming of the surface by the sun. Thermals are commonly used by birds and glider pilots to extend flight duration, increase cross-country distance, and conserve energy. This kind of powerless flight using natural sources of lift is called soaring. Once a thermal is encountered, the pilot flies in circles to keep within the thermal, so gaining altitude before flying off to the next thermal and towards the destination. A single thermal can net a pilot thousands of feet of elevation gain, however estimating thermal locations is not ...


Comparison Of Airline Co-Branded Credit Card Programs Via Frequent Flyer Money Saver Analysis For Full-Service U.S. Carriers, Bora Suavi Unsal 2021 Embry-Riddle Aeronautical University

Comparison Of Airline Co-Branded Credit Card Programs Via Frequent Flyer Money Saver Analysis For Full-Service U.S. Carriers, Bora Suavi Unsal

PhD Dissertations and Master's Theses

Although airline alliances work fairly effectively for paid flight segments, passengers who want to redeem frequent flyer miles often encounter difficulties. Sometimes airlines demand an extensive amount of air miles to book requests for award seats to not only their partner airline customers but also their own customers. Furthermore, while the airline co-branded credit card award mile earnings and redemption rates fluctuate significantly between different airlines, passengers are not well informed about which airline co-branded credit card requires the minimum amount of credit card expenditure to fly with an award ticket to their desired travel destination.

A more useful and ...


Mindfulness Workshop For Airline Pilots, Eric Miller 2021 Lesley University

Mindfulness Workshop For Airline Pilots, Eric Miller

Mindfulness Studies Theses

The science on mindfulness as it relates specifically to aviation is sparse. It has only been in recent years that mindfulness has been examined as it relates to aviation. That being the case, this paper draws connections from areas that are already well studied with mindfulness; stress, anxiety, attention, and communication. Evidence exists that even short duration mindfulness interventions can have positive effects on mindfulness. The one-day workshop created with this thesis gives pilots a cursory overview of mindfulness as it relates to various areas of commercial aviation. Furthermore, the workshop will teach pilots how these different mindfulness techniques can ...
