Abstract The organization’s role in establishing a culture fertile for safety development, risk management and mitigation is paramount. Barriers to the effectiveness of aviation safety systems may emerge when human biases interfere with the basic processes of safety management systems. Biases come in many forms and can serve as unconscious discriminatory behaviors against a...

Speech Interfaces and Pilot Performance: A Meta-Analysis

As the aviation industry modernizes, new technology and interfaces must support growing aircraft complexity without increasing pilot workload. Natural language processing presents just such a simple and intuitive interface, yet the performance implications for use by pilots remain unknown. A meta-analysis was conducted to understand performance effects of using speech and voice...

Over the last decades, the development of 3D textile composites has been driven the structures developed to overcome disadvantages of 2D laminates such as the needs of reducing fabrication cost, increasing through-thickness mechanical properties, and improving impact damage tolerance. 3D woven, stitched, knitted and braided preforms have been used as composites reinforcement for...

Low Level Turbulence Detection For Airports

Abstract—— Low level wind shear and turbulence present a serious safety risk to aircraft during the approach, landing and take-off phases. Despite many advances in on-board and ground based warning systems. Wind shear remains a formidable force that coupled with a microburst can overpower any aircraft. Aviation reports have concluded that pilots need to have improved information...
