A panel of the SAE A-5A Committee prepared this SAE Aerospace Information Report (AIR). The document describes the design approaches used for current applications of Brake-by-Wire (BBW) control systems that are used on commercial and military airplanes. The document also discusses the experience gained during service in the commercial and military environments, and covers system, ergonomic, hardware, and development aspects. The treatment 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 systems that use the electro-hydraulic method of control. The overall range of implementations is briefly described in 2.3. Sections 3, 4, and 5 describe the electro-hydraulic method in detail.

This standard covers minimum requirements for skid control equipment for use on all types and models of civil aircraft. It shall be the responsibility of the applicant to determine the compatibility of these requirements with the application aircraft and to specify requirements in excess of these minimums as necessary.

This SAE Aerospace Recommended Practice (ARP) provides recommendations for the function, design, construction, and testing of an on-aircraft Brake Temperature Monitoring System (BTMS), sometimes referred to as a Brake Temperature Indication System (BTIS). NOTE: This ARP does not address: Cockpit ergonomics and Aircraft operating procedures. Various handheld methods of temperature sensing or readouts, as these are not associated with transport aircraft during normal operation. Temperature sensitive paints as a means to indicate exceedance of a landing gear axle temperature threshold due to brake temperature.

This SAE Aerospace Recommended Practice (ARP) is intended to provide guidance on verifying the integrity of inflation pressure sealing systems of aircraft wheel/tire assemblies.

The aircraft landing gear is a complex multi-degree of freedom dynamic system, and may encounter vibration or dynamic response problems induced by braking action. The vibratory modes can be induced by brake and tire-ground frictional characteristics, antiskid operation, brake design features, landing gear design features, and tire characteristics. The impact of this vibration can range from catastrophic failure of critical system components or entire landing gears, to fatigue of small components, to passenger annoyance. It is therefore important that the vibration is assessed during the design concept phase, and verified during the development and testing phases of the system hardware. This SAE Aerospace Information Report (AIR) has been prepared by a panel of the A-5A Subcommittee to present an overview of the landing gear problems associated with aircraft braking system dynamics, and the approaches to the identification, diagnosis, and solution of these problems.

This technical report documents three surveys to determine realistic vibration requirements for skid control systems specifications and obtain updated vibration information for locations in aircraft where skid control system components are mounted.

This SAE Aerospace Standard (AS) defines the configuration of aircraft wheel inflation valve assemblies, including required tolerances, materials, and appropriate finishes.

This SAE Aerospace Information Report (AIR) documents general technical data associated with many of the wheels used in the Air Force.

This SAE Aerospace Information Report (AIR) is intended to provide general background on aircraft wheel service lives on military aircraft and wheel laboratory test requirements as specified by military procurement agencies or aircraft manufacturers. Wheel service life in this document refers to the lowest life wheel half or flange in a wheel assembly measured in years (excluding bearing, bolt, and other removals). This information is intended as a reference guide for those responsible for specifying original equipment (OE) wheel laboratory test requirements.
