AIR5372A
This SAE Aerospace Information Report (AIR) describes the design approaches used for current applications of aircraft Brake-by-Wire (BBW) control systems. The document also discusses the experience gained during service, and covers system, ergonomic, hardware, and development aspects. The document includes the lessons that have been learned during application of the technology. Although there are a variety of approaches that have been used in the design of BBW systems, the main focus of this document is on the current state of the art systems.

J2382_201407
Scope—Traditional methods of photometry rely on the use of a goniometer to rotate the test item around two axes at right angles. This method is satisfactory for most situations but has certain disadvantages: a. Point-by-point measurements with a goniometer may be slow. With more advanced requirements, particularly for headlamps, where the entire beam pattern is of concern, isocandela measurements are becoming increasingly needed. Such testing can be very time consuming. b. For production quality assurance, the speed of a goniometer may not allow testing to keep pace with the production line if a large quantity of lamps must be sampled. c. High Intensity Discharge (HID) lamps are becoming commonly used. Such lamps are orientation sensitive, changing in both lumen output and intensity distribution when tilted. This can introduce significant inaccuracies in test results when testing is performed using a goniometer.

AS6332
A program, which ensures quality with the relevant standards shall be introduced for all on-line Stations where de-icing/anti-icing of aircraft on the ground is either normally carried out, or where local conditions may periodically lead to a requirement for airplcraft to be de-iced/anti-iced. Deficiencies, in regard to a Station's local de-icing/anti-icing procedures, shall be identified and subsequently actioned through this program, thereby ensuring that the required safety standards are maintained.

AS9968
This AS describes a standard method for viscosity measurements of thickened (AMS1428) anti-icing fluids. Fluid manufacturers may publish alternate methods for their fluids. In case of conflicting results between the two methods, the manufacturer method takes precedence. To compare viscosities, exactly the same measurement elements (including spindle and container size) must have been used to obtain those viscosities.

AS81820D
This SAE Aerospace Standard (AS) covers plain spherical bearings which are self-aligning and self-lubricating by utilizing polytetrafluoroethylene (PTFE) in a fabric composite or molded material that is bonded to the inner diameter surface of the race and when specified, to the bore diameter surface of the ball. These bearings are for use in the temperature range -65 to +325 °F (-54 to +163 °C).

This document specifies the procedure to be used for a manufacturer to certify the net power and torque rating of a production engine according to J1349 (Rev. 8/04) or the gross engine power of a production engine according to SAE J1995. Manufacturers who advertise their engine power and torque ratings as Certified to SAE J1349 or SAE J1995 shall follow this procedure. Certification of engine power and torque to J1349 or J1995 is voluntary, however, this power certification process is mandatory for those advertising power ratings as "Certified to SAE J1349".

ARP60495
This method is currently under development in the E-34C Lubricating Characteristics subcommittee as a technique to predict the micropitting performance of 5 cSt turbine oils. The PCS Instruments Micro pitting rig (MPR) is currently used by the Industry to look at both macro and micro pitting resistance of lubricating oils on gears and bearings. Using the test methods and profile developed from testing performed by Powertrib, and then further discussions between PCS Instruments (the instrument manufacturer) and the E-34C committee, a set of proposed test conditions have been agreed. Once the specimens have been manufactured, a small round robin is planned to look at repeatability and reproducibility.

J1674
The purpose of this SAE Standard is to offer simplified and prioritized guidelines for collecting and preserving on-scene data related to motor vehicle accidents. It is intended that these guidelines improve the effectiveness of data collection, which will assist subsequent analysis and reconstruction of a particular incident. The document is to guide early data collectors whose objectives include documenting information related to the incident. it may be used by law enforcement personnel, safety officials, insurance adjusters and other interested parties. The document identifies categories of scene physical features that deteriorate relatively quickly and recomends documentation task priorities. Detailed methods of collecting data are not part of this document. However, some widely used methods are described in the references in Seciton 2.
