This report is intended to identify the necessary analytical tools to enable making value judgments for minimizing the various errors typically encountered in capacitance systems. Thus, in addition to identification of error sources, it describes the basic factors which cause the errors. When coupled with appraisals of the relative costs of minimizing the errors, this knowledge will furnish a tool with which to optimize gauging system accuracy, and thus, to obtain the optimum overall system within the constraints imposed by both design and budgetary considerations. Since the subject of capacitance accuracy is quite complex, no attempt is made herein to present a fully-comprehensive evaluation of all factors affecting gauging system accuracy. Rather, the major contributors to gauging system inaccuracy are discussed and emphasis is given to simplicity and clarify, somewhat at the expense of completeness. An overview of Capacitive Fuel Gauging operation is provided in the Appendix.

The importance of adequate component procurement specifications to the success of a hardware development program cannot be overemphasized. Specifications which are too stringent can be as detrimental as specifications which are too lax. Performance specifications, for instance, must not only identify all the component requirements, but they must also include sufficient quality assurance provisions so that compliance can be verified. It should be understood that in almost every case specifications for components will ultimately become part of a BINDING, WRITTEN CONTRACT (PO). The purpose of this document is to describe specifications, provide guidance for the preparation of fluid component specifications, and identify documents commonly referenced in fluid component specifications.

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.

The test procedure applies to the refueling manifold system connectingn the receiver aircraft fuel tanks to the refueling source fuel pump(s) for both ground and aerial refueling. The test procedure is intended to verify that the limit value for surge pressure specified for the receiver fuel system is not exceeded when refueling from a refueling source which meets the requirements of AS1284 (reference 2). This recommended practice is not directly applicable to surge pressure developed during operation of an aircraft fuel system, such as initiating or stopping engine fuel feed or fuel transfer within an aircraft, or the pressure surge produced when the fuel pumps are first started to fill an empty fuel manifold.

This report lists documents that aid and govern the design of gas turbine powered aircraft and missile fuel systems. The report lists the military and industry specifications and standards and the most notable design handbooks that are commonly used in fuel system design. The specifications and standards section has been divided into two parts, a master list arranged numerically of all industry and military specifications and standards and a component list that provides a functional breakdown and a cross-reference of these documents. It is intended that this report be a supplement to specifications MIL-F-8615; MIL-F-17874; MIL-F-38363 and MIL-F-87154. Revisions and amendments which are correct for the specifications and standards are not listed. The fuel system design handbooks are listed for fuels and for system and component design.

To describe general guidelines for achieving selected levels of cleanliness in gas turbine engine fuel system components and to describe laboratory type 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) is a compilation of engineering references and data useful to the technical community that can be used to ensure fuel system compatibility with composite structure. This AIR is not a complete detailed design guide and is not intended to satisfy all potential fuel system applications. Extensive research, design, and development are required for each individual application.

This Aerospace Recommended Practice (ARP) covers a brief discussion of the icing problem in aircraft fuel systems and different means that have been used to test for icing. Fuel preparation procedures and icing tests for aircraft fuel systems and components are proposed herein as a recommended practice to be used in the aircraft industry for fixed wing aircraft and their operational environment only. In the context of this ARP, the engine (and APU) is not considered to be a component of the aircraft fuel system, for the engine fuel system is subjected to icing tests by the engine/APU manufacturer for commercial and specific military applications. This ARP is written mostly to address fuel system level testing. It also provides a means to address the requirements of 14 CFR 23.951(c) and 25.951(c). Some of the methods described in this document can be applied to engine and APU level testing or components of those application domains. This revision does not completely address new developments in ice accretion resulting from internal flow in tubing.

This SAE Aerospace Standard (AS) also defines the features and dimensions for airframe refueling ports on civil aircraft that require the exclusive use of turbine fuel as an engine fuel. In addition, this document defines the minimum fuel nozzle spout dimensions for turbine fuel ground service equipment, and the maximum fuel nozzle spout diameter for gasoline ground service equipment.

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. Entrained water will settle out in time under static conditions and may or may not be drained, depending on the rate at which it is converted to free water.
