Impact of Changes in Test Dust Contaminants and Particle Counter Calibration on Laboratory Filter Element Performance and Fluid Cleanliness Classes

2003-07-03
HISTORICAL
AIR5455
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.

GRAVITY REFUELING NOZZLES AND PORTS INTERFACE STANDARD FOR CIVIL AIRCRAFT

1984-12-01
HISTORICAL
AS1852
This Aerospace Standard (AS) defines maximum free opening dimensions for airframe refueling ports on civil aircraft that require the exclusive use of aviation gasolines, and minimum free opening dimensions for airframe refueling ports on civil aircraft that operate with turbine fuels as a primary fuel type. In addition, this document defines the minimum refueling nozzle tip dimensions for turbine fuels ground service equipment, and the maximum refueling nozzle tip diameter dimension for aviation gasolines ground service equipment.

Fuel Level Point Sensing

2020-11-30
CURRENT
AIR6325
This report is intended to identify the various existing technologies used for a fuel level sensing system. In addition to sensing technologies, it describes the basic architecture of fuel level sensing systems and their association with fuel gauging system to increase integrity of fuel measurement and management. As the fuel level sensing system is generally based on electrical components within fuel tanks, a specific focus is made on fuel tank explosion safety protection. An overview of the capacitive fuel gauging operation can be found in AIR5691.

HISTORICAL
AIR1660B
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.
