Jet Fuel

Jet Fuel Testing

In aviation, safety suffers no compromise. Crews, airframes, engines, oil and fuel must be in perfect condition before getting the ‘’Cleared to takeoff’’ authorisation from Air Traffic Control.

Extreme care must be taken to protect aviation fuel tanks and refuelling trucks from contamination. Just like regular gasoline and diesel fuel, both Avgas (used in small piston aircraft) and Jet Fuel (used in turboprops and jet airliners) are indeed exposed to water, microbiological, rust, dirt and other contaminants.

In addition, aircraft fuel tanks are at risk of water contamination as they go through humid air during climbing and landing operations, causing ice crystals which are likely to block filters and fuel lines, and interrupt the fuel flow to the engine. Fuel System Icing Inhibitor (FSII) is a pure ethylene (or diethylene) glycol monomethylether additive that lowers the freezing point of water thus preventing ice build-up. Its purity must be assessed to ensure maximum effectiveness in absorbing water molecules from ambient humid air.

Jet A fuel has a freezing point of -40 °C. Jet A-1 freezes at -47 °C and the freezing point of Jet B, mainly used in military aircraft, is at -60 °C. At Tribologik, testing FSII and jet fuel contamination and freezing point is our contribution to global aviation safety.
