ARP6316
This SAE Aerospace Recommended Practice (ARP) documents a common understanding of terms, compliance issues, and occupant injury criteria to facilitate the design and certification of oblique facing passenger seat installations specific to Part 25 aircraft. The applicability of the criteria listed in this current release is limited to seats with an occupant facing direction greater than 18 and no greater than 30 degrees relative to the aircraft longitudinal axis. Later revisions are intended to provide criteria for other facing directions. Performance criteria for side facing seats installed with the occupant facing direction at 90 degrees relative to the aircraft longitudinal axis are provided in AS8049/1. Seats installed at angles greater than 30 degrees relative to the aircraft longitudinal axis must have an energy absorbing rest or shoulder harness. However, this document does not provide the criteria for oblique facing seats incorporating such rests.

This document provides information and guidance material to assist in assessing the need for and feasibility of developing deicing facilities, the planning (size and location) and design of deicing facilities, and assessing environmental considerations and operational considerations associated with de-icing facilities. The document presents relevant information necessary to define the need for a deicing facility and factors influencing its size, location and operation. The determination of the need for deicing facilities rests with Airports. Although this document intends to provide information to airport operator and deicing facility planner/designer, all stakeholders, including deicing service providers, should be involved in the development process.

New dawn at Honda R&D President Yoshiyuki Matsumoto aims to invigorate Honda's technology and product-development organization with 'full soul.' Automated driving meets regulation: NHTSA and the next 50 years The challenges and opportunities on the road to 'zero deaths' demand a new level of federal automotive safety technical standards, and a new safety-defect reporting and recall system. NHTSA and the U.S. Congress must act boldly and quickly to make it happen. Autonomous driving meets regulation: Hands off, eyes off, brain off Euro NCAP'S president warns that without coherent policies, the growing availability of automated technologies may result in piecemeal technology development-and unintentional consequences. Designer yin meets engineer yang Efficient and effective vehicle development means even closer collaboration between the two former sparring partners.

This document will provide methodologies and procedures to validate active safety test targets and correlate them to the objects they are intended to represent. The Correlation procedure will document a means of measuring representative object characteristics and specifying acceptability criteria for a test target using that objective characteristic measurement. The Validation procedure will be utilized to determine if the test target meets the acceptability criteria. A Confirmation procedure will identify unacceptable characteristic deviations of the targets during use in the field. Test targets may include cars, pedestrians, motorcycles, bicycles, or any other object that may be encountered by a vehicle.

The objective of this document is to enhance the test procedure that is used for ejection mitigation testing per the NHTSA guidelines as mentioned in the FMVSS226 Final Rule document (NHTSA Docket No. NHTSA-2011-0004). The countermeasure for occupant ejection testing is to be tested with an 18kg mass on a guided linear impactor using the featureless headform specifically designed for ejection mitigation testing. SAE does not endorse any particular countermeasure for ejection mitigation testing. However, the document reflects guidelines that should be followed to maintain consistency in the test results. Examples of currently used countermeasures include the Inflatable Curtain airbags and Laminated Glass.

In order to realize the benefits of Integrated Vehicle Health Management (IVHM) within the aerospace and defense industry there is a need to address five critical elements of data interoperability within and across the aircraft maintenance ecosystem, namely • Approach • Trust • Context • Value • Security In Integrated Vehicle Health Management (IVHM) data interoperability is the ability of different authorized components, systems, IT, software, applications and organizations to securely communicate, exchange data, interpret data, use the information and derive consistent insight from the data that has been exchanged to derive value.

This SAE Aerospace Standard (AS) defines Minimum Performance Standards (MPS), qualification requirements, and minimum documentation requirements for side-facing seats in civil rotorcraft, transport aircraft, and general aviation aircraft. The goal is to achieve comfort, durability, and occupant protection under normal operational loads and to define test and evaluation criteria to demonstrate occupant protection when a side-facing seat/occupant/restraint system is subjected to statically applied ultimate loads and to dynamic test conditions set forth in Title 14, Code of Federal Regulations (CFR) Part 23, 25, 27, or 29. While this document addresses system performance, responsibility for the seating system is divided between the seat supplier and the installation applicant. The seat supplier’s responsibility consists of meeting all the seat system performance requirements and obtaining and supplying to the installation applicant all the data prescribed by this document.

Abstract Studies have shown that the number of road accidents caused by rollover both in Europe and in Turkey is increasing [1]. Therefore, rollover related accidents became the new target of the studies in the field of vehicle dynamics research aiming for both active and passive safety systems. This paper presents a method for optimizing the rear suspension geometry using design of experiment and multibody simulation in order to reduce the risk of rollover. One of the major differences of this study from previous work is that it includes statistical Taguchi method in order to increase the safety margin. Other difference of this study from literature is that it includes all design tools such as model validation, optimization and full vehicle handling and ride comfort tests. Rollover angle of the vehicle was selected as the cost function in the optimization algorithm that also contains roll stiffness and height of the roll center.

In 1966, Congress boldly reshaped the American approach to road safety and thereby established the United States as the worldwide leader in vehicle safety. Congressional action led to the establishment of the Department of Transportation, the National Highway Traffic Safety Administration (NHTSA), Federal Motor Vehicle Safety Standards, and the motor-vehicle safety defects and recall system. However, the safety environment that gave rise to these responses has evolved substantially. Fifty years later, the United States is unable to properly regulate rapidly advancing safety technologies, and the recall system is wholly unsuited to ensuring the safety of software-driven systems. Congress must act to update the road safety system in order to enable the United States to meet the challenges and seize the opportunities of the new transportation era.
