This SAE Aerospace Information Report (AIR) provides general information on the developing subject of synthetic jet fuels derived from non-petroleum feed stocks. It addresses synthetic jet fuel properties and other topics associated with their use and is intended as a guide to assist aviation fuel system designers in considering important information on fuel properties when designing aircraft fuel systems and components. The AIR is limited to “drop-in” fuels that meet the requirements of the respective fuel specifications and are compatible with typical aircraft and ground refueling systems. While some key properties are included in this AIR for discussion, the reader should utilize documents such as MIL-HDBK-510 or the ASTM International research reports for a more-detailed review of fuel properties. AIR7484 also gives more details on fuel properties, specifically as they relate to airframe fuel system design.

To describe general guidelines for achieving selected levels of cleanliness in gas turbine engine fuel system components and to describe laboratory methods for measuring and reporting the contamination level of the wetted portion of fuel system components. As in SAE J1227 (covering hydraulic components) this practice includes guidelines for levels of acceptance but does not attempt to set those levels.

This SAE Aerospace Information Report (AIR) discusses the impact of the ISO Test Dusts, chosen as replacement contaminants for the Arizona Test Dusts (AC Test Dusts), and the ISO calibration procedure ISO 11171 for automatic particle counters, which replaces the calibration procedure ISO 4402 (1991), on laboratory performance of filter elements utilized in aerospace lubrication, hydraulic and fuel systems, and fluid cleanliness levels determined with automatic particle counters.

A fuel level control valve/system controls the quantity of fuel in a tank being filled or emptied. This document provides a general familiarization with these mechanisms (e.g. forms they take, functions, system design considerations). This document provides the aircraft fuel system designer with information about these mechanisms/devices, so that he can prescribe the types of level control valves/systems which are best suited for his particular fuel system configuration.

Ice formation in aircraft fuel systems results from the presence of dissolved and undissolved water in the fuel. Dissolved water or water in solution with hydrocarbon fuels constitutes a relatively small part of the total water potential in a particular system with the quantity dissolved being primarily dependent on the fuel temperature and the water solubility characteristics of the fuel. One condition of undissolved water is entrained water such as water particles suspended in the fuel as a result of mechanical agitation of free water or conversion of dissolved water through temperature reduction. Another condition of undissolved water is free water which may be introduced as a result of refueling or the settling of entrained water which collects at the bottom of a fuel tank in easily detectable quantities separated by a continuous interface from the fuel above. Water may also be introduced as a result of condensation from air entering a fuel tank through the vent system.

This document establishes requirements, test procedures, and acceptance criteria for the fire testing of fluid handling components and materials used in aircraft fluid systems. It is applicable to fluid handling components other than those prescribed by AS1055 (e.g., hoses, tube assemblies, coils, fittings). It also is applicable to materials, wiring, and components such as reservoirs, valves, gearboxes, pumps, filter assemblies, accumulators, fluid-cooled electrical/electronic components, in-flight fluid system instrumentation, hydromechanical controls, actuators, heat exchangers, and manifolds. These components may be used in fuel, lubrication, hydraulic, or pneumatic systems.

This SAE Aerospace Information Report (AIR) reviews performance testing parameters for noncleanable, often referred to as disposable, aircraft gas turbine engine lubricant filter elements.

This report lists military and industry specifications and standards which are commonly used in aerospace gas turbine fuel systems. It is intended as a supplement to specifications MIL-F-3863, MIL-F-17874 and MIL-F-8615. Revisions and amendments which are current for these specifications and standards are not listed.
