Airships In U.N. Humanitarian And Peace Operations: Ready For Service?, Walter Dorn, Nic Baird, Robert Owen Jan 2018

Airships In U.N. Humanitarian And Peace Operations: Ready For Service?, Walter Dorn, Nic Baird, Robert Owen

Journal of Aviation/Aerospace Education & Research

This study examines whether the United Nations should take steps in the near future to exploit the operational characteristics of lighter-than-air (LTA) and hybrid aircraft in support of its peace and humanitarian operations. Continued progress in the development of LTA transport system makes this a timely issue. At the same time, this progress highlights persistent challenges to the conduct of reliable and safe LTA operations, particularly in the face of bad weather and threats from groups hostile to the UN mission. The report examines this issue in four sections: (1) the potential advantages of LTA operations; (2) their disadvantages; (3) …


Called To Safety? Individual And Combined Effects Of Safety Climate And Occupational Callings On Aviator Safety Performance, Michele W. Gazica, Erin E. Bowen, Michael A. Mccarson, Kristen A-M. Chadwell Jan 2018

Called To Safety? Individual And Combined Effects Of Safety Climate And Occupational Callings On Aviator Safety Performance, Michele W. Gazica, Erin E. Bowen, Michael A. Mccarson, Kristen A-M. Chadwell

Journal of Aviation/Aerospace Education & Research

This study examined the individual and combined effects of two potential antecedents to aviation-related safety performance: safety climate and occupational callings. Research exploring the importance of occupational callings to the safety domain is in its nascent stages. The extent that someone is living a calling may explain variance in actual safety performance above that which can be explained by safety climate alone. Survey data from aviators in a flight training program were analyzed to evaluate the ability of occupational calling assessments to inform the potential for safety mishaps within the aviation industry. Results indicate that both safety climate and occupational …


Human Error Analysis Of Helicopter Emergency Medical Services (Hems) Accidents Using The Human Factors Analysis And Classification System (Hfacs), Paul E. Cline Ph.D. Jan 2018

Human Error Analysis Of Helicopter Emergency Medical Services (Hems) Accidents Using The Human Factors Analysis And Classification System (Hfacs), Paul E. Cline Ph.D.

Journal of Aviation/Aerospace Education & Research

Helicopter Emergency Medical Services (HEMS) is among the most dangerous type of flying in commercial aviation. This research utilized the Human Factors Analysis and Classification System (HFACS) to understand the errors, preconditions and violations that contribute to these accidents. Drawing upon source data from the National Transportation Safety Board’s Aviation Accident Database, HEMS accidents from 2000-2016 were analyzed according to the HFACS framework.


Using 3 Dimension Health Vegetation Index Point Clouds To Determine Hlb Infected Citrus Trees, Joseph Cerreta, Ashley Hanson, Julianna E. Martorella, Stacy Martorella Jan 2018

Using 3 Dimension Health Vegetation Index Point Clouds To Determine Hlb Infected Citrus Trees, Joseph Cerreta, Ashley Hanson, Julianna E. Martorella, Stacy Martorella

Journal of Aviation/Aerospace Education & Research

Three-dimensional NDVI point clouds can be an innovative method for detecting Huanglongbing (HLB) disease in citrus trees. In February 2018, an Unmanned Aircraft System (UAS) captured narrow-band multispectral images to detect healthiness variations of infected citrus trees. A 30-acre section of a citrus grove in Florida with a known HLB infection was examined to determine if three-dimensional Normalized Difference Vegetation Index (NDVI) point clouds can indicate healthiness variations in HLB-infected citrus trees and how three-dimensional NDVI point clouds compared to two-dimensional NDVI reflectance maps for detecting healthiness variations in HLB-infected citrus trees. Wilcoxon Sign Rank testing compared Whole-Tree Vegetation Indices …
