The UCS technical governance comprises a set of policies, processes, and standard definitions to establish consistency and quality in the development of architecture artifacts and documents. It provides guidance for the use of adopted industry standards and modeling conventions in the use of Unified Modeling Language (UML) and Service Oriented Architecture Modeling Language (SoaML), including where the UCS Architecture deviates from normal UML conventions. This document identifies the defining policies, guidelines, and standards of technical governance in the following subjects: - Industry standards adopted by the AS-4UCS Technical Committee: These are the industry standards and specifications adopted by AS-4UCS in the generation and documentation of the architecture. - UCS Architecture Development: UCS specific policies on the development of the UCS Architecture. The AS-4UCS Technical Committee governance policies are intentionally minimal.

This document defines a set of standard application layer interfaces called JAUS Mobility Services. JAUS Services provide the means for software entities in an unmanned system or system of unmanned systems to communicate and coordinate their activities. The Mobility Services represent the vehicle platform-independent capabilities commonly found across all domains and types of unmanned systems (referred to as UxVs). At present, over 15 services are defined in this document many of which were updated in this revision to support Unmanned Underwater Vehicles (UUVs). Some examples include:

General criteria are presented as guidelines for: control device location, resistance, and actuation of hand and foot controls by the machine's operator. The criteria are based upon physical limitations as defined by human factors engineering principles. This SAE Recommended Practice applies to upright seated operators of Road Building and Maintenance, and Specialized Mining Machinery categories of off-road, self-propelled work machines as identified in SAE J1116. The criteria presented should apply to most situations. Each situation, however, must be evaluated as to its own function and its relationship to other functions to achieve the desired operation action in normal and emergency situations with high probability. The values for control displacement and resistance apply only to what is required to achieve the desired performance of the function being controlled for the 5th through the 95th percentile person as defined in ISO 3411.

This document was prepared by the SAE AS-1A2 Committee to establish techniques for validating the Network Controller (NC) complies with the NC requirements specified in AS5653, Revision B. Note that this verification document only verifies the specific requirements from AS5653 and does not verify all of the requirements invoked by documents that are referenced by AS5653. The procuring authority may require further testing to verify the requirements not explicitly defined in AS5653 and in this verification document.

This document defines a set of standard application layer interfaces called JAUS Mission Spooling Services. JAUS Services provide the means for software entities in an unmanned system or system of unmanned systems to communicate and coordinate their activities. The Mission Spooling Services represent the platform-independent capabilities commonly found across all domains and types of unmanned systems. At present, 1 service is defined in this document (more services are planned for future versions of this document): • Mission Spooler: Stores mission plans, coordinates mission plans, and parcels out elements of the mission plan for execution The Mission Spooler service is described by a JAUS Service Definition (JSD) which specifies the message set and protocol required for compliance. The JSD is fully compliant with the JAUS Service Interface Definition Language [JSIDL].

Abstract Modern military aircraft platforms are using more and more power which results in an ever increasing power density (SWaP). This in turn, generates more heat that has to be dissipated from the instrument panel and cockpit of the aircraft. Complicating this further is that the use of structural composites which are not efficient conductors of heat and the mission requirements of small heat signatures. Therefore alternative means of extracting the heat from the avionics systems must be used. Liquid cooled systems have the advantage over air cooled systems of a much higher heat transfer rate and the fact that the heat can be transported a significant distance from the source. Liquid cooled avionics have their own challenges as well.

I Certification of a mono or multicore processor is going to request to demonstrate that we are able to master the determinism of the execution for all the applications which are going to be executed. Regarding the multicore we introduce a level of complexity to be managed regarding the execution of the application in parallel on each of the cores of the multicore processor whatever is the internal architecture of the processor. In an IMA context: This determinism is insured by the control of the WCET allowing defining a maximal boundary for all the accesses to all the services offered by the Operating System. The Platform Provider has no information about the applications which are going to be executed by his platform. In this condition the computation of a WCET on a multi-core, like it is done currently on a mono-core, will be realized by introducing constraints at the level of the internal functioning of the multi-core processor.

Abstract Avionics industry is moving towards more electric & lightweight aircrafts. Electromagnetic effects becomes significantly challenging as materials starts moving towards composite type. Traditional methods for controlling EMC will not be sufficient. This shift increases the complexity of in-flight hardware elements for EMI/EMC control. This paper discusses the need for EMI/EMC Control and brings out the analysis & applicability of various EMI/EMC standards in aerospace, commercial and industrial electronic products, provides comparative study with respect to levels. The study include various sections of DO-160 and applicable guidelines for controlling EMI/EMC with respect to LRU (Line Replaceable Unit) & wire/cable harnesses. Also presents guidelines with respect to shielding of components, selection of components, grounding schemes, filter topologies and layout considerations.

Abstract Of all aircraft power and thermal loads, flight controls can be the most challenging to quantify because they are highly variable. Unlike constant or impulsive loads, actuator power demands more closely resemble random processes. Some inherent nonlinearities complicate this even further. Actuation power consumption and waste heat generation are both sensitive to input history. But control activity varies considerably with mission segment, turbulence and vehicle state. Flight control is a major power consumer at times, so quantifying power demand and waste heat is important for sizing power and thermal management system components. However, many designers sidestep the stochastic aspects of the problem initially, leading to overly conservative system sizing. The overdesign becomes apparent only after detailed flight simulations become available. These considerations are particularly relevant in trade studies comparing electric versus hydraulic actuation.

This Aerospace Standard (AS) 5659/4 Physical Layer Specification provides guidance for the physical layer of optical networks which use Wavelength Division Multiplexing (WDM), within the AS5659 WDM LAN specification document family. The physical layer consists of the optical interconnections between the functional components of the network. Performance requirements for general interconnections are described. For guidance, standards are identified, corresponding to each of several environments, which describe physical layer design, installation, maintenance, and training.

The Loran-C Radionavigation System, managed by the U.S. Coast Guard, is the federally provided radionavigation system for civil marine use in the U.S. coastal waters. It is also designated by the Federal Aviation Administration (FAA) as a supplementary system in the National Airspace System (NAS). This system provides accurate radionavigation and timing services to users in the United States of America and Canada. Loran-C is also being used and developed by several other countries in Europe and Asia. Estimates of Loran-C system accuracy must take into consideration the transmitted signal, signal propagation, signal reception, interference or errors from outside sources such as natural and man-made electromagnetic noise, skywave contamination, geometric dilution of precision, other Loran-C signals, communication information superimposed on the navigation signal, and coordinate conversion.
