The purpose of this document is to evaluate Communication, Navigation, and Surveillance (CNS) Distributed Radio architectures and the feasibility of distributing the RF and systems processing sections to ensure the following: Reduce cost of equipment Reduce Size, Weight, and Power (SWaP) Ease of aircraft integration Growth capability built into the design Maintain or improve system availability, reliability, and maintainability It provides a framework to determine whether it is feasible to develop ARINC Standards that support CNS distributed radio architectures.

ARINC 800 is the first industry standard intended for characterization of aviation-grade high-speed (Gbps) Ethernet links. The test methods are based on realistic representation of cabin networks. The notional cabling architecture is based on IFE seat distribution using multiple intermediate disconnects. Sequential testing is supported by building up number of connectors in the link. Test guidelines for mixed intermediate cable lengths are provided.

The increase in molarity (M) of the acidic solution beyond 3M resulted a higher dispersion rate and a lower crystallinity. In the case of using a high-reflux temperature, helical CNTs which were processed with a 3M or 16M acids displayed a substantial increase in the solubility compared to the ones which were refluxed at a low temperature. ...In the case of using a high-reflux temperature, helical CNTs which were processed with a 3M or 16M acids displayed a substantial increase in the solubility compared to the ones which were refluxed at a low temperature.

A series of standard double-cantilever-beam (DCB) specimens have been bonded by three structural 3M epoxy adhesives selected from different applications. The specimens were tested under monotonic and cyclic opening loads (mode-I) in order to evaluate the quasi-static and fatigue performances of selected adhesives at room temperature, 80°C and -40°C.

Due to modern trends in the automotive industry, such as vehicle electrification, light-weighting, reduced NVH (Noise, Vibration and Harshness) packaging space, etc., it is desirable to have a low profile and light-weight acoustic material with multi-functionality. If one single layer of a thin acoustic material can provide comparable absorption and transmission loss to a multilayer treatment, it will benefit the industry by saving weight, packaging space and system cost. Acoustic absorption and sound transmission loss performance of a new dissipative material at reduced weight and thickness is introduced in this paper. The acoustic performance of the material was evaluated by using random incidence absorption and transmission loss as well as in-vehicle experiment. Further potential applications for this material have been identified using the Statistical Energy Analysis (SEA) method with panel leakage considered.

This specification prescribes general requirements for marking of aircraft ground support equipment and other vehicles (i.e., runway sweepers, firetrucks, refuelers, etc.), used on or near the flight line area with retro-reflective materials.

This SAE Aerospace Standard (AS) covers laboratory test methods required to evaluate nonflammable hydraulic fluids. The methods of testing and description of the equipment have been used typically for evaluating chlorotrifluoroethylene (CTFE) base hydraulic fluids.

ARINC 429 defines the most-widely used data transfer method used within and among avionics systems. It specifies the physical data bus, the electrical characteristics, and the data word formats. Supplement is 18 is a routine update that assigns new ARINC 429 labels, equipment IDs, and System Address Labels (SAL). The document is a re-mastering to bring it up-to-date with the latest ARINC Standard formats and styles.

For decades, ceramic fiber mats have been used to mechanically support substrates in catalytic converters. Intumescent mats, those that expand with heat, are composed primarily of ceramic fibers, vermiculite, and organic binder. The binder is required for manufacturing, handling, and installation. Unfortunately, under cool operating conditions, its effects on mat performance are often negative. While residual binder is not an automatic precursor to premature failure, it can amplify the effects of other factors such as gap control and vibration. As the mat mount material is heated, sections can become soft and pliable. In the absence of sufficient heat for complete binder removal, regions of the mat may become rigid during the cooling cycle. This results in a decrease in mat resiliency. Several tests can be used to show the relationship between binder level and material performance. These tests typically characterize expansion properties and pressure performance.

Also included were measurements taken on a 3m diameter tire noise dynamometer with surfaces replicating test track pavements. Variation between facilities appears to be a function of both design/construction and pavement age.

This document is limited to units meeting the definitions of para. 1.3 and covers the following general class of synchros: 26 volt, 400 cycle synchros 115 volt, 400 cycle synchros 115 volt, 60 cycle synchros

The primary goal of this standard is to describe the nature of Electrostatic Discharge (ESD) and its effects on digital avionics equipment. It provides information concerning methods to protect against ESD damage which could originate in many different ways.

This information report is being issued to cover conversions from inch-pound units to those in the System International (SI) approach. Since all conversions cannot possibly be covered, the list contained in Section 4 is composed of the lighting oriented items which are found in SAE or Motor Vehicle Safety Standard (MVSS) in North America. This reference is to FMVSS in the United States and to CMVSS in Canada. The purpose of this report is to give guidance for uniformity particularly to those organizations, governmental or otherwise, who may in the future have occasion to express present inch-pound units in metric or SI terms.

This standard sets forth the desired characteristics of a second-generation aviation Ku-band and Ka-band satellite communication (satcom) system intended for installation in all types of aircraft.
