For an “end-to-end passenger experience that is secure, seamless and efficient” the International Air Transport Association (IATA) proposes Near Field Communication (NFC) and a single token concept to be enablers for future digital travel. NFC is a wireless technology commonly utilized in Portable Electronic Devices (PEDs) and contactless smart cards. It is characterized by the following two attributes: a tangible user interface and secured short range communication. While manufacturers are currently adapting PED settings to enable NFC in the flight mode, the integration and use of this technology in aircraft cabins still remains a challenge. There are no explicit qualification guidelines for electromagnetic compatibility (EMC) testing in an aircraft environment available and there is a lack of a detailed characterization of NFC equipped PEDs.

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. The architecture of the components (cold plates, etc) used for extracting the heat from the electronics component must be optimized to perform consistently and reliably while maintaining the smallest footprint possible in the already crowded instrument panel.

Certification of a mono or multicore processor is going to request to demonstrate that we are capable of mastering the determinism of the execution of 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, in a mono-core processor: • 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. In this condition the computation of a WCET on a multi-core, like it is done currently, will be realized by introducing constraints at the level of the internal functioning of the multi-core processor.

AS4111A
This SAE Aerospace Standard (AS) contains a sample test plan for AS 15531 or MIL-STD-1553B Remote Terminals (RT) that may serve several different purposes. This document is intended to be contractually binding when specifically called out in a specification, Statement of Work (SOW), or when required by a Data Item Description (DID). Any and all contractor changes, alterations, or testing deviations to this section shall be separately listed for easy review. The purpose of these tests is to verify that the Unit Under Test (UUT) responds properly in accordance with the requirements of the governing standard. The tests are not intended to verify the mission aspects stated in the equipment specification. The pass criteria is defined in each test paragraph. If any test fails, record the UUT response to that test. This general test plan is intended for design verification of remote terminals designed to meet the requirements of AS 15531 and MIL-STD-1553B with Notice 2.

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.

AS15531A
This SAE Aerospace Standard (AS) contains requirements for a digital time division command/response multiplex data bus, for use in systems integration, that is functionally equivalent to MIL-STD-1553B with Notice 2. Even with the use of this document, differences may exist between multiplex data buses in different system applications due to particular application requirements and the options allowed in this document. The system designer must recognize this fact and design the multiplex bus controller (BC) hardware and software to accommodate such differences. These designer selected options must exist to allow the necessary flexibility in the design of specific multiplex systems in order to provide for the control mechanism, architectural redundancy, degradation concept, and traffic patterns peculiar to the specific application requirements.
