Unsettled Domains Concerning Autonomous System Validation and Verification Processes

EllectroCrafts Aerospace-Fabio Alonso da Silva
  • Research Report
  • EPR2019012
To be published on 2019-12-20 by SAE International in United States
The Federal Aviation Administration (FAA) and the Department of Transportations' (DOT's) National Highway Traffic Safety Administration (NHTSA) face similar challenges regarding the regulation of autonomous systems powered by artificial intelligence (AI) algorithms that replace the human factor in the decision-making process. The validation and verification (V&V) processes contribute to the implementation of the correct system requirements. The V&V process is one of the steps of a development lifecycle starting with the definition of regulatory, marketing, operational, performance, and safety requirements. They define what a product is, and they flow down into lower level requirements defining control architectures, hardware, and software. The industry is attempting to define regulatory requirements and a framework to gain safety clearance of such products. This report suggests a regulatory text and a safety and V&V approach from an aerospace engineering perspective assessing the replacement of the human driver from the decision-making role by a computational system. This article suggests an approach where aerospace guidelines can be used alongside ISO 26262 in order to define a viable and valuable framework for autonomous…

Lighting Applications for Unmanned Aircraft Systems (UAS)

A-20B Exterior Lighting Committee
  • Aerospace Standard
  • ARP6336
  • Current
Published 2019-12-05 by SAE International in United States

This SAE Aerospace Recommended Practice (ARP) provides technical recommendations for the lighting applications for Unmanned Aircraft Systems (UAS). The technical content of this ARP discusses the unique trade-offs that are necessary to maintain commonality to the U.S. Federal Aviation Regulations (FARs) for aerospace lighting. The recommendations set forth in this document are to aid in the design of Unmanned Aircraft (UA) lighting for the size of aircraft and operation for which the aircraft is intended. In addition, certain concepts of operation for which UASs are suited will require unique lighting solutions.

Inspection and Maintenance of In-Use Motor Vehicles – Mitigating Environmental impact

International Centre for Automotive Technology-Vijayanta Ahuja, Aditya Gautam
  • Technical Paper
  • 2019-28-2427
Published 2019-11-21 by SAE International in United States
The existing rule no. 62 of CMVR, 1989 applies to various commercial vehicles and yet is unable to provide a promising template to have a concise format which will cover all the motor vehicles and their different components with more precise equipment plus virtual testing along with proper management of time during the bulk inspection of all the vehicles. This paper will include all the technicalities and the different course of actions which must be taken into account for the proper implementation of the desired regulations on the designated concern. The idea behind this paper is to have a compact procedural document for the periodical inspection and maintenance of all the motor vehicles running on the Indian Roads that adhere to the basic safety concerns of other on-road vehicles, the pedestrians and the surroundings. Concluding the fact that there are various aspects of environmental degradation henceforth we start by picking one of the hazards trying to execute a method to resolve every respective issue on a micro level, thus eliminating maximum threats onto the environment.…

Reducing Risk with Geometric Transition Extrusion

  • Magazine Article
  • TBMG-35498
Published 2019-11-01 by Tech Briefs Media Group in United States

In an effort to design smaller, more intricate and complicated medical devices without running afoul of increasingly stringent national and international regulations, many designers are looking to geometric transition extrusions manufactured of high consistency rubber (HCR) silicone. This process reduces total cost of ownership for the original equipment manufacturer while improving part quality and greatly enhancing the types of devices being sought by healthcare providers.

The Challenge of Replacing Hard Chrome

Aerospace & Defense Technology: October 2019

  • Magazine Article
  • 19AERP10_03
Published 2019-10-01 by SAE International in United States

The search for a suitable replacement for hard chrome on aerospace components has been a key supply chain priority for aircraft manufacturers. This is because of the documented health risks to workers and the impact on the environment from exposure to hexavalent chromium, a carcinogen that occurs during the chrome plating process and is the most toxic form of chromium.

Halogen Light Source Performance Requirements for Motor Vehicle Forward Lighting

Lighting Standard Practices Committee
  • Ground Vehicle Standard
  • J2560_201909
  • Current
Published 2019-09-04 by SAE International in United States
This document establishes performance, material, and design requirements and design guidelines for halogen replaceable light sources used in road illumination devices for forward lighting. Non-halogen filament light sources suitable for forward lighting are specified in SAE J573. The terms “high beam filament” and “low beam filament” used throughout this document refer only to typical use, not to a mandatory, exclusive, or universal function of the filaments. This SAE Recommended Practice is periodically updated to keep pace with experience and technical advances.

Published 2019-09-03 by SAE International in United States
This SAE Aerospace Information Report (AIR) contains regulatory and guidance information related to transport airplane hydraulic systems. It contains certain Civil Air Regulations (CAR) and Federal Aviation Regulations (formerly referred to as FARs) from Title 14 Code of Federal Regulations (CFR) in their current version as well as the historical versions. This gives the reader an ability to assemble certain CAR/CFR parts as they existed at any date in the past (referred to as a Regulatory Basis). A certain amount of preamble explanatory material is included, which led to the regulatory rule changes (Amendments to the CFR).
