J3078/4 specifies a uniform test method for measuring the contribution to operator environmental temperature provided by a heating, ventilating and air conditioning system operating in a specific ambient environment. The method might not determine the complete climatic environment of the operator since this is also affected by heat load from sources other than those on the machine, for example solar heating. J3708/6 is to be used in conjunction with J3078/4 to determine more accurately the complete heat loading on the operator enclosure. Minimum performance levels for the machine’s operator enclosure heating, ventilating and air conditioning systems are established in J3708/4.

Abstract Counterfeit items can be viewed as the by-product of a supply chain which has been compromised. While many industries are impacted, certain types of products can mean the difference between life and death. Electronics are of special interest, however, mechanical parts can also have dire consequences. The point is that the counterfeiting community is very diverse. The business model is fluid and unrestricted. Electronics today…hardware tomorrow. All of this leads to the need for an authentication platform that is agnostic to product. Most supply chains would benefit from a technical way to have assurance of authenticity - a benefit that could be shared by all. A comprehensive marking program, such as SigNature DNA, offers value to all supply chain participants as outlined below: Manufacturers will have the ability to effectively monitor their legacy components Authorized distributors will have an absolute way to verify and accept returns Defense contractors and agencies will have forensically authentic and traceable inventory at their disposal End users will have the power to authenticate stock to the component level

Abstract Upon their arrival, Unmanned Autonomous Systems (UAS) brought with them many benefits for those involved in a military campaign. They can use such systems to reconnoiter dangerous areas, provide 24-hr aerial security surveillance for force protection purposes or even attack enemy targets all the while avoiding friendly human losses in the process. Unfortunately, these platforms also carry the inherent risk of being built on innately vulnerable cybernetic systems. From software which can be tampered with to either steal data, damage or even outright steal the aircraft, to the data networks used for communications which can be jammed or even eavesdropped on to gain access to sensible information. All this has the potential to turn the benefits of UAS into liabilities and although the last decade has seen great advances in the development of protection and countermeasures against the described threats and beyond the risk still endures. With this in mind the present work will describe a monitoring system whose purpose is to monitor UAS mission profile implementation at both high level mission execution and at lower level software code operation to tackle the specific threats of malicious code and possible spurious commands received over the vehicle's data links.

Abstract This paper summarizes the Power, Avionics and Software (PAS) 1.0 subsystem integration testing and test results that occurred in August and September of 2013. This paper covers the capabilities of each PAS assembly to meet integration test objectives for non-safety critical, non-flight, non-human-rated hardware and software development. This test report is the outcome of the first integration of the PAS subsystem and is meant to provide data for subsequent designs, development and testing of the future PAS subsystems. The two main objectives were to assess the ability of the PAS assemblies' to exchange messages and to perform audio tests of both inbound and outbound channels. This paper describes each test performed, defines the test, the data, and provides conclusions and recommendations.

This equipment specification covers requirements for Multi-Tasking Equipment (MTE) for airfield snow removal purposes. The unit shall include a combination of a carrier vehicle, snow plow, rotary broom and high velocity air blast system. This vehicle as a unit shall be an integrated snow plow, rotary broom and high velocity air blast. Primary application is for the high-speed plowing, sweeping and cleaning of ice and snow from airfield operational areas such as runways, taxiways and ramp aprons. The term carrier vehicle represents the various self-propelled prime movers that provide the motive power necessary to move snow and ice control equipment during winter operations. The airport operator may require this specified piece of equipment in order to maintain the airfield during large and small snow events. When necessary, the MTE shall be a central and critical element in the winter pavement maintenance fleet in the effort to accomplish the airport’s published snow plan. This ARP defines the minimum functionality for a vehicle to be classified as an MTE, specifically as an integrated snow and ice removal system capable of performing multiple and simultaneous functions requiring no more than one operator.

Over the years, the DARPA Challenges in the United States have galvanized interest in autonomous cars, making them a real possibility in the mind of the public, but autonomous and unmanned vehicles have been increasingly employed in many roles on land, in the water, and in the air. Military applications have received a great deal of attention, with weaponized unmanned aircraft (drones) being the most prominent. However, unmanned vehicles with varying degrees of autonomy already have many civilian applications. Some of these are quite familiar (such as the Roomba autonomous vacuum cleaner), while others remain largely out of the public eye (such as autonomous farm equipment). Additional applications and more capable vehicles are rapidly coming to the markets in the years ahead. This book examines a number of economically important areas in which unmanned and autonomous vehicles, also understood here as autonomous technologies, are already used or soon will be. Co-published by SAE International and AUVSI, Autonomous Technologies: Applications That Matter will assist the reader in identifying profitable opportunities and avoiding costly misconceptions with respect to civilian applications of autonomous vehicle technologies as it brings together chapters on how air, water, and ground vehicles are becoming ever more used and appreciated.

Counterfeit electronic components entering into critical infrastructure and applications through the global supply chain threaten the economy and national security. In response to the growing threat from counterfeits, the Society of Automotive Engineers G-19 Committee is developing AS6171. This aerospace standard is focused on testing facilities with a goal of standardizing the process of counterfeit detection. An integral part of the standard is a semi-quantitative risk assessment method. This method assigns risk scores to electronic components based on a number of relevant criteria, and places the components into one of five risk tier levels corresponding to an appropriate level of laboratory testing to ensure the authenticity of the component. In this way, the methodology aims at standardizing the risk assessment process and bases the identified risk as guidance for commensurate testing protocols. This paper outlines the risk assessment method contained within AS6171 and briefly explores other complementary efforts and research gaps within the G-19 and electronics community.
