An Hfacs Analysis Of German F-104 Starfighter Accidents, Steven Esser, Hans-Joachim K. Ruff-Stahl
An Hfacs Analysis Of German F-104 Starfighter Accidents, Steven Esser, Hans-Joachim K. Ruff-Stahl
Journal of Aviation Technology and Engineering
From 1961 onwards, Germany acquired 916 Lockheed F-104 Starfighters, of which 292 aircraft crashed and 116 pilots lost their lives. The purpose of this research project was to find out why these aircraft crashed and whether the Starfighters crashed for reasons different from those for other military aircraft in Germany. Seventy-one German F-104 accidents between 1978 and 1986 were analyzed by reviewing the original accident files. A Human Factors Analysis and Classification System (HFACS) Level-1 analysis was used as methodology. It was found that more than 50% of the reviewed German F-104 accidents occurred due to technology and/or physical environment. …
Human Factors Analysis And Classification System (Hfacs): As Applied To Asiana Airlines Flight 214, Alex Small
Human Factors Analysis And Classification System (Hfacs): As Applied To Asiana Airlines Flight 214, Alex Small
The Journal of Purdue Undergraduate Research
The Human Factors Analysis and Classification System (HFACS) is a safety tool that aids in the identification and analysis of organizational factors that contribute to aircraft accidents. By using the HFACS model, safety investigators can better understand the existing conditions that contribute to accidents, which then allows for the development and implementation of safety programs to prevent these conditions. In this study, the HFACS framework was utilized to identify the human factors that contributed to the Asiana Airlines flight 214 accident that occurred on July 6, 2013. The results of this study indicate that inadequate pilot training, lack of upper-level …
Incidence Of An Astronaut Not Sealing The Pressure Garment Visor On Reentry, Cameron M. Smith, Trent Tresch
Incidence Of An Astronaut Not Sealing The Pressure Garment Visor On Reentry, Cameron M. Smith, Trent Tresch
Journal of Human Performance in Extreme Environments
Audiovisual records of a Project Mercury pilot’s activities during an orbital flight indicate that his visor was left open during reentry and descent to the sea surface, phases of flight during which cabin pressure loss was to be mitigated by suit pressurization; however, the suit could not have been pressurized with the visor open. Thus, for a presently unknown reason, a critical safety step—sealing the visor and making a pressure suit integrity test before reentry—was overlooked in this flight. Later, Space Shuttle flights were carried out with visors unsealed for much of the launch and landing phases, with the false …
Enhancing A Flight Dispatcher Display For Safer Flight Operations, Jeongjoon Boo
Enhancing A Flight Dispatcher Display For Safer Flight Operations, Jeongjoon Boo
Open Access Theses
This study assesses capability of flight dispatchers to adopt enhancements on their display that enables detection of flights in abnormal activities and investigation of the causes. Three approaches were used. First, the expected function for enhancements was designed by collecting information from different places about what technologies are available for consideration. Second, hierarchical task analysis was conducted based on data collected by interviewing a former flight dispatcher in order to assess operational capability to handle the enhancement. Third, based on the results of first two approaches, a display prototype that includes the enhancement was developed and evaluated for usability and …
An Integrated Framework For Fostering Human Factor Sustainability And Increased Safety In Aviation Ramp Operations, Sarah M. Hubbard, Denver Lopp
An Integrated Framework For Fostering Human Factor Sustainability And Increased Safety In Aviation Ramp Operations, Sarah M. Hubbard, Denver Lopp
Journal of Aviation Technology and Engineering
The aviation work environment has one of the highest accident rates of any industry sector in the United States, resulting in significant costs for both employee injuries and equipment damage. In fact, injury rates exceed rates found in areas that are widely recognized as hazardous, such as construction and mining, and it is estimated that aircraft ground damage costs are as high as 5 billion to 10 billion dollars per year. Purdue University’s Aviation Technology Department has conducted numerous safety and human factors studies in the past decade encompassing maintenance and repair operations, corporate flight departments, and over ten major …
Evaluating Intensity As A Controller Function For Nextgen Scenarios With Increased Capacity, Caitlin Anne Surakitbanharn
Evaluating Intensity As A Controller Function For Nextgen Scenarios With Increased Capacity, Caitlin Anne Surakitbanharn
Open Access Theses
Automated separation assurance is the most mature concept to handle increasing airspace traffic and capacity needs, yet the system lacks a way to pre-emptively identify aircraft separation problems. The intensity control measure looks to find situations where if an aircraft pair makes an unplanned change in heading or altitude at the wrong moment, an unrecoverable situation arises. This research analyzes static, open loop air traffic data in an en-route sector to determine how many high intensity aircraft pairs (HIP) exist per minute, and if the intensity measure is a safely manageable function for air traffic controllers. It is found that …
The Effect Of Job Performance Aids On Quality Assurance, Erik David Fosshage
The Effect Of Job Performance Aids On Quality Assurance, Erik David Fosshage
Open Access Theses
Job performance aids (JPAs) have been studied for many decades in a variety of disciplines and for many different types of tasks, yet this is the first known research experiment using JPAs in a quality assurance (QA) context. The objective of this thesis was to assess whether a JPA has an effect on the performance of a QA observer performing the concurrent dual verification technique for a basic assembly task. The JPA used in this study was a simple checklist, and the design borrows heavily from prior research on task analysis and other human factors principles. The assembly task and …
