There has been a recent upsurge in interest from the media concerning the quality of the environment within aircraft cabins and cockpits especially in the commercial world1-4. This has included (although by no means been limited to) the air quality, with particular reference to the alleged effects of contamination from the aircraft turbine lubricant. Possible exposure to ‘organophosphates’ (OPs) from the oil has raised special concerns from cabin crew. Such is the concern that government organisations around the world, including Australia, USA and UK, have set up committees to investigate the cabin air quality issue. Concern was also voiced in the aviation lubricants world at the way in which OP additives in turbine lubricants were being blamed in some reports for the symptoms being experienced by air crew and passengers. SAE Committee E-34 therefore decided that it should gather as much available information on the subject as possible.

This specification covers a one-part fluorosilicone (FVMQ) adhesive/ sealant, supplied in cartridges, suitable for extrusion and curing to an elastomeric material upon exposure to air. It also covers a compatible primer.

This SAE Aerospace Recommended Practice (ARP) describes a procedure for determining the insoluble contamination level of the downstream side of filter elements. Results of this procedure represent the particulate released from the tested filter element under the prevailing conditions of the test. The results may be used for comparative evaluation of the effectiveness of various cleaning methods or the cleanliness of elements after cleaning or as received from manufacturers.

The scope of this Aerospace Recommended Practice (ARP) covers where, when, and how often to sample hydraulic system fluid on aerospace vehicles for particulate contamination measurements. The measurement of hydraulic fluid particulate contamination is of concern to the aerospace community because of the critical importance of hydraulic equipment reliability. Contamination is always present in the system fluid, even in new unused fluid. Contamination must be below a level that will not adversely affect system operation. This ARP draws from aerospace industry experience and practice to establish criteria for fluid contamination sampling recommendations in aerospace vehicle hydraulic systems. Fluid samples can then be subjected to measurement of particulate contamination and of other harmful contaminants such as chlorinated solvents and water.

This SAE Aerospace Standard defines cleanliness levels for particulate contamination of hydraulic fluids and includes methods of reporting data relating to the contamination levels. The contamination levels selected are an extension and simplification of the widely accepted NAS 1638.

This Aerospace Information Report (AIR) describes a mathematical model that can be used to analyze particle count data. Particle counts that fit the model can be graphically displayed, converted from one counting size-frequency range to another, and extrapolated to estimate counts beyond the measured range. Derivation, applications and calculations are described.

These recommendations are written to cover the general requirements of helicopter air conditioning and are sub-divided as follows: (1) Air Conditioning System - Dealing with the general design aspects. (2) Air Conditioning Equipment - Design requirements for satisfactory system function and performance. (3) Air Conditioning System Design Requirements -General information for use of those concerned in meeting requirements contained herein.

This document is reissued for application to helicopters. It is primarily intended to apply to the engine or engines, but it shall also apply to fire protection of lines, tanks, combustion heaters, and auxiliary powerplants (APU). Post-crash fire protection is also discussed.

The purpose of this Aerospace Recommended Practice is to standardize test equipment and procedures for the measurement of smoke emission from aircraft gas turbine engines. The procedures included are for determining and reporting the amount of smoke emission. This document is divided into the following sections: 1 Definitions and Terminology 2 Equipment 3 Test Procedures 4 Information and Data to be Recorded 5 Data Reduction and Analysis 6 Presentation of Results

This Aerospace Recommended Practice (ARP) standardizes test equipment and procedures for the measurement of smoke emission from aircraft gas turbine engines. The procedures included are for determining and reporting the amount of smoke emission. Tests have indicated that the practically achieveable precision of the smoke number is within ±3 when the system is properly used as outlined herein. This procedure is not intended for in-flight testing, nor does it apply to afterburning engines.

The environmental factors of prime importance in the transport of animals in aircraft are air temperature, humidity and carbon dioxide concentration, and of course space (or volume) limitations. Secondary factors are air velocity, noise, lighting, etc. Pressure is not addressed herein as pressure levels and rates of change are totally dictated by human occupancy requirements. Some basic governmental documents, such as References 1, 2 and 3, define overall requirements for animal transportation, but with very limited data on environmental requirements. Reference 4 gives some airplane characteristics measured during animal transportation from the USA to foreign destinations. Temperature and humidity profiles are indicative of airplane characteristics. This report presents information on the temperature, humidity, ventilation, and carbon dioxide limitations and the metabolic heat release rates for animals which will allow the determination of the environment required by the animals.

This specification covers reinforced rubber and reinforced thermoplastic hose, or hose assemblies, intended for conducting liquid and gaseous dichlorodifluoromethane (refrigerant 12) in automotive air conditioning systems. The hose shall be designed to minimize permeation of refrigerant 12 and contamination of the system and to be serviceable over a temperature range of -30 to 120°C (-22 to 248°F). Specific construction details are to be agreed upon between user and supplier.
