The presence of human factors in aviation remains a critical area of research given the safety implications of human error. Understanding what specific factors contribute to human error allows managers and operators to take steps to mitigate these hazards. Several methods have been tested in the cockpit and cabin crew environments, but less attention has been given to the aviation maintenance sector, despite the prevalence of accidents resulting from human error. With the introduction of AC-172A, the FAA validated the need for additional research and training on the role of human factors in aviation maintenance errors. However, a key component …

Gender Differences And Cockpit Design, Susan Archer, Heidi Brewer, Stacie Fain, Stephanie Smith

Student Works

The design project reported in this paper examined female pilots’ experiences with how well or poorly cockpit design allowed them to safely accomplish their flying missions. The general aviation aircraft cockpit is not designed for female pilots, often causing them to find ways to adapt to the cockpit in order to operate the aircraft safely. Two primary focal areas for adaptations address issues with accessibility of controls and “viewability” inside and outside the cockpit. The design team used a Situation Awareness-Oriented Interface Design (SAOD) approach in preparing cockpit design recommendations for general aviation aircraft that would accommodate female pilots.

General Aviation Hypoxia And Reporting Statistics, Timothy B. Holt, Jacqueline Luedtke, Claire Schindler

Publications

“All too often, pilots tell me they don't need physiological training because they don't fly that high. The statement points out the general feelings of a large majority of the aviation population. I suppose then the burning question is ‘why do we still have aircraft accidents?’” (Boshers, 2015). To this day there are no statistics on how often general aviation pilots experience hypoxia during everyday operations. General aviation pilots (i.e. non-commercial operations) were chosen for this study because:

• Little regulation regarding flight physiology training
• General attitude of invulnerability towards hypoxia
• No requirement to report hypoxia or similar events

Cirrus Cloud Microphysics Over Darwin, Australia, Dorothea Ivanova, Matthew Johnson

Publications

Ice clouds, crucial to the understanding of both short - and long - term climate trends, are poorly represented in global climate models (GCMs). Cirrus clouds, one of the largest uncertainties in the global radiation budget, have been inadequately studied at low latitudes. Parameterizations exist for mid - latitude and tropical cirrus ( Ivanova et al. 2001; McFarquhar et al. 1997). Due to climate sensitivity in the GCM with respect to cloud input, without robust parameterizations of cirrus clouds, the GCM is inaccurate over most output fields, including radiative forcing, temperature, albedo, and heat flux (Yao and Del Genio 1999). …
