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
This SAE Aerospace Standard (AS) covers the requirements for a flexible, lightweight, low pressure, self-extinguishing, integrally heated silicone hose assembly. The hose has a fully fluorinated fluoropolymer inner liner and is primarily intended for use in aircraft potable water systems with an environmental operating temperature range of -65 °F (-54 °C) to +160 °F (+71 °C).
This specification covers the general requirements for integrally illuminated information panels.
This SAE Aerospace Standard (AS) establishes the minimum performance standards for equipment used as secondary alternating current (AC) electrical power sources in aerospace electric power systems.
This specification covers a silicone rubber in the form of a two-component liquid.
This SAE Aerospace Recommended Practice (ARP) provides guidance for substantiating the airworthiness of aircraft engine components. Generally these components are associated with the engine control system, the system or systems that allow the engine to provide thrust or power as demanded by the pilot of the aircraft while also ensuring the engine operates within acceptable operating limits. But these components may also include hardware and systems associated with engine lubrication, engine or aircraft hydraulic or electrical systems, aircraft environmental control systems, thrust reverser control, or similar aircraft or engine propulsion system functions. This paper develops the concept of using a 26 item matrix of environmental conditions for evaluating aircraft engine component airworthiness. This approach is compatible with current practices used in the industry and has been accepted by engine certification authorities as part of engine certification programs.
This Recommended Practice is intended to outline the design, installation, testing, and field maintenance criteria for a high temperature metal pneumatic duct system, for use as a guide in the aircraft industry. These recommendations are to be considered as currently applicable and necessarily subject to revision from time to time, as a result of the rapid development of the industry.

This specification covers an optical-quality, transparent, polycarbonate plastic, to which a hard protective surface coating has been applied, supplied in the form of flat sheet or formed parts made from flat sheet.
This Aerospace Standard (AS) covers the general minimum performance standards for generators/starter-generators and associated voltage regulators for use in direct current (DC) electric systems for civil aircraft.
This publication is applicable to liquid cooling systems of the closed loop type and the expendable coolant type in which the primary function is transporting of heat from its source to a heat sink. Most liquid cooling system applications are oriented toward the cooling of electronics. Liquid cooling techniques, heat sinks, design features, selection of coolants, corrosion control, and servicing requirements for these systems are presented. Information on vapor compression refrigeration systems, which are a type of cooling system, is found in Reference 1.
This standard covers oronasal type masks which use a continuous flow oxygen supply. Each such mask comprises a facepiece with valves as required, a mask suspension device, a reservoir, or rebreather bag (when used), a length of tubing for connection to the oxygen supply source, and a means for allowing the crew to determine if oxygen is being delivered to the mask. The assembly shall be capable of being stowed suitably to meet the requirements of its intended use.
This SAE Aerospace Standard (AS) establishes the general requirements for a miniature probe type self-sealing, self-aligning, non-locking coupling intended for aerospace liquid cooling systems. The AS5072/slash sheets define the specific performance and dimensional requirements.
This specification covers electrical connections made with single, solid, round copper or copper alloy wire wrapped around copper alloy terminals without the use of solder.
This document defines the minimum performance standards for personnel parachute assemblies to be carried in aircraft or worn by passengers, crew, or parachutists for emergency use. This document covers three types of personnel carrying parachute assemblies and the operating limitations for each:
This SAE Recommended Practice provides guidance for defining the requirements for evaluating hydraulic pumps and motors and for preparing detailed specifications for these components. The user can follow this document to set forth the pump and motor environmental and performance considerations, establish service life and reliability goals, and define specific evaluation tests for marine vehicle applications.
The purpose of this recommended practice is to provide recommendations concerning the procedure for wave soldering.
This specification covers a room-temperature-vulcanizing, elastomeric silicone compound.
This document covers resolvers which are used to perform coordinate transformations as well as sine and cosine computations, It includes both the categories of compensated and uncompensated resolvers which perform these functions. Linear resolvers are also included because of their similarity to resolvers.
