Applying Lean To The Ac-130 Maintenance Process For The Royal Saudi Air Force, Fisal A. Alzahrani

Theses and Dissertations

The ideas expressed in this research come from the researchers experiences working in the AC-130 maintenance squadron in the Royal Saudi Air Force. The AC-130 maintenance process is not currently being used as effectively as it could be to make AC-130 fully mission capable. That can be done by improving communication, reducing distances needed to move or transport anything during the maintenance process and by efficient use of the available qualified workforces, tools and equipment. Consideration is given to applying an existing management technique to the Royal Saudi Air Forces AC-130 Maintenance Squadrons. The selected technique is the Lean management …

Seeing The Threat: Pilot Visual Detection Of Small Unmanned Aircraft Systems In Visual Meteorological Conditions, Jon M. Loffi, Ryan J. Wallace, Jamey D. Jacob, Jared C. Dunlap

International Journal of Aviation, Aeronautics, and Aerospace

One key challenge of integrating Unmanned Aircraft Systems (UAS) platforms into the National Airspace System (NAS) is the potential for midair collisions between manned aircraft and the unmanned system. The lack of an established UAS benchmark for Detect, Sense & Avoid Systems put the preponderance of avoidance efforts on manned aircraft pilots to visually see and avoid potential collision threats. The small size, unusual configurations, and diverse operational applications of unmanned systems make UAS platforms difficult to visually identify. This paper sought to determine the mean visibility distance of small UAS systems (sUAS) to an alerted pilot flying a general …

On Safety Assessment Of Novel Approach To Robust Uav Flight Control In Gusty Environments, Vladimir Golubev, Petr Kazarin, William Mackunis, Sherry Borener, Derek Hufty

Publications

In a follow-up to our previous study, the current work examines the gust-induced “cone of uncertainty” in a small unmanned aerial vehicle’s (UAV) flight trajectory addressed in the context of safety assessments of UAV operations. Such analysis is a critical facet of the integration of unmanned aerial systems (UAS) into the National Airspace System (NAS), particularly in terminal airspace. The paper describes a predictive, robust feedback-loop flight control model that is applicable to various classes of UAVs and unsteady flight-path scenarios. The control design presented in this paper extends previous research results by demonstrating asymptotic (zero steady-state error) altitude regulation …

Trust In Automation: A Study Of Helicopter Pilot Perception On Enhanced Flight Vision Systems (Efvs), Nicholas Colby Currie

Theses and Dissertations

Trust in automation is a growing field of research that serves a vital role in understanding how humans interact with modern technology. Though automation is certainly becoming more prevalent in many professions, it has become a mainstay in the modern helicopter cockpit. One particular piece of modern aviation technology that incorporates a significant amount of automation is Enhance Flight Vision Systems (EFVS). EFVS technology provides pilots with a wealth of information that enables them to “see” under low visibility conditions, thereby increasing their situational awareness. Though the benefits of EFVS technology are easily recognizable, it is still an automated system …

Position Paper: Safety Culture: Why The Faa Should Consider Adapting The Wings Pilot Proficiency Program As A Method Of Remote Pilot Recertification, Ryan J. Wallace

International Journal of Aviation, Aeronautics, and Aerospace

The FAA’s release of 14 CFR 107 establishes a new Remote Pilot certification for operation of small unmanned aircraft system (UAS) platforms. Remote Pilot privileges are valid for two years, during which the operator must complete a recurrent aeronautical knowledge test covering the seven topical areas of knowledge identified by 14 CFR 107.73(b). While the existing recertification methods allow for validation of remote pilot knowledge, they fail to engage this new group of aviators in establishing positive safety culture. The author proposes the Federal Aviation Administration (FAA) adapt the existing framework for the WINGS Pilot Proficiency Program to offer regular …

Toward Risk Assessment 2.0: Safety Supervisory Control And Model-Based Hazard Monitoring For Risk-Informed Safety Interventions, Francesca Favaro, Joseph Saleh

Faculty Publications

Probabilistic Risk Assessment (PRA) is a staple in the engineering risk community, and it has become to some extent synonymous with the entire quantitative risk assessment undertaking. Limitations of PRA continue to occupy researchers, and workarounds are often proposed. After a brief review of this literature, we propose to address some of PRA׳s limitations by developing a novel framework and analytical tools for model-based system safety, or safety supervisory control, to guide safety interventions and support a dynamic approach to risk assessment and accident prevention. Our work shifts the emphasis from the pervading probabilistic mindset in risk assessment toward the …
