As the aerospace industry continues on its quest for ever-increased efficiency, so goes the quest for ever-more composite content on aircraft. And with it, more opportunities to repair it. Typical composite panel fiber reinforcements are carbon, aramid, and fiberglass. The machining techniques for these typical composite materials are similar, but minor differences exist, such as the style of cutting tool or drill bit. Automated drilling methods that may be used during original manufacture are rarely used in typical composite repair situations.

This SAE Aerospace Recommended Practice (ARP) document covers the requirements for a Snowcompressor with carrier vehicle used to clear snow from airport operational areas by compressing the volume of collected snow into smaller volumes for loading into a hauling/dump truck or for depositing reduced-volume windrows for snow banking. The term carrier vehicle represents the various self-propelled prime movers that provide the power necessary to move snow and ice control equipment during winter operations. For two-stage rotary plows that primarily are used to cast heavy concentrations of snow away from airport operational areas such as runways and taxiways, see ARP5539.

This document defines key terms and concepts for relating effects of driver distraction on driving performance, physiological indicators, subjective assessments, or combinations thereof to effects of driver distraction on crash involvement. These concepts are intended to contribute to methodologies for assessing driver distraction metrics in terms of their reliability, repeatability, bias, and predictive or descriptive validity and distraction evaluation procedures in terms of their real-world representativeness. The actual specification of such a methodology is outside the scope of the present document. While the focus is on driver distraction evaluation for technology evaluations and driver activities, the concepts described herein may be applicable also to other forms of driving performance evaluation. The intended users of the document are practitioners in the industry, academia and other organizations with an interest in driving performance assessment and road safety.

Abstract Digital human models (DHM) have greatly enhanced design for the automotive environment. The major advantage of the DHMs today is their ability to quickly test a broad range of the population within specific design parameters. The need to create expensive prototypes and run time consuming clinics can be significantly reduced. However, while the anthropometric databases within these models are comprehensive, the ability to position the manikin’s posture is limited and needs lot of optimization. This study enhances the occupant postures and their seating positions, in all instances the occupant was instructed to adjust to the vehicle parameters so they were in their most comfortable position. While all the Occupants are accommodated to their respective positions which finally can be stacked up for space assessments. This paper aims at simulating those scenarios for different percentiles / population which will further aid in decision making for critical parameters.

Abstract Traffic awareness of the driver is one of the prime focus in terms of pedestrian and road safety. Driver experience plays a significant role and driving requires careful attention to changing environments both within and outside the vehicle. Any lapse in driver attention from the primary task of driving could potentially lead to an accident. It is observed that, lack of attention on the ongoing traffic and ignorant about the traffic information such as traffic lights, road signs, traffic rules and regulations are major cause for the vehicle crash. Traffic signals & signage are the most appropriate choice of traffic control for the intersection, it is important to ensure that driver can see the information far away from the intersection so that he/she can stop safely upon viewing the yellow and red display. Then, upon viewing the signal operations and conditions the motorist can stop his/her vehicle successfully before entering the intersection.
