This SAE Aerospace Information Report (AIR) provides background information, technical data and related technical references for minimization of electrostatic hazards in aircraft fuel systems. Techniques used to minimize the electrostatic hazard include: a Reducing fueling rate into tank bays including use of multiple refueling inlet nozzles. b Reducing refuel plumbing flow velocities. c Introducing fuel into the tank at a low velocity near the bottom and directing it to impinge upon a grounded conducting surface. d Avoiding electrically isolated conductors in the fuel tank. e Using conductivity additives in the fuel.
To describe useful methods for conducting pressure drop tests of fuel system components for MIL-F-8615 or similar requirements and to present general suggestions for improving accuracy of test results.

This document describes a number of jet fuel properties and where applicable gives the specification limits for Jet A and Jet A-1, though the properties are generally applicable to all turbine fuels. Later versions of this document will give more details on specification limits for other similar fuels, such as TS-1, where they differ from Jet A and Jet-A1. It gives details about the possible impact on airframe fuel system design.
The "Scope" section may be a very brief statement describing the coverage of the specification for a simple device, or it may require a long description of limiting parameters for a more complex device or system having a complicated interface definition.
This SAE Aerospace Information Report (AIR) is limited to the subject of aircraft fuel systems and the questions concerning the requirements for electrical bonding of the various components of the system as related to Static Electric Charges, Fault Current, Electromagnetic Interference (EMI) and Lightning Strikes (Direct and Indirect Effects). This AIR contains engineering guidelines for the design, installation, testing (measurement) and inspection of electrical bonds.
