Safety Versus Security in Aviation [PDF]

open access: yes, 2020
Abstract The two domains safety and security have traditionally been kept separated in aviation. While the first treats risks associated with aviation activities, the latter safeguards civil aviation against acts of unlawful interference. While national and international guidelines exist in addressing the installation of risk management for ...

Position Paper: Safety Culture: Why the FAA Should Consider Adapting the WINGS Pilot Proficiency Program as a Method of Remote Pilot Recertification

open access: yesInternational Journal of Aviation, Aeronautics, and Aerospace, 2016
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 ...

Manned Versus Unmanned Aircraft Accidents, Including Causation and Rates

open access: yesInternational Journal of Aviation, Aeronautics, and Aerospace, 2018
Many consider aircraft reliability a primary deterrent to the further integration of unmanned aircraft into civil airspace. Discussions of unmanned aircraft reliability often include comparisons of accident rates of medium and large unmanned aircraft ...

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Sustainable Carbon Fibers Enable Stable Long‐Term Lithium Metal Deposition for Prospective Zero‐Excess Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work presents lightweight, lignin‐derived carbon fiber current collectors that enable controlled lithium deposition. Structural defects and intermediate‐sized pores stabilize pre‐nucleation quasi‐metallic lithium clusters, promoting uniform lithium plating and stripping.
