It's an anti-icing additive for Jet-A. Some places have it pre-mixed, and some places add it into your fuel upon your request.

GauleyPilot

or, marketed by PPG under the brand name Prist is a fuel additive that acts as a anti-icing agent in aircraft fuel systems.
It is added by being blended with fuel as it is pumped into the aircraft. It comes in an aerosol can that has a hose that clips to the fuel nozzle, or it can be blended in at the truck.

It can also be pre-blended at the bulk plant before fuel is delivered to the airport.

It's the feeling you get when your pay is cut 40% and you pension goes away.

It also is an anti-microbial. So when they ask you that in training you can say it does both.

The formulation for Prist Hi-Flash used to be an ethylene glycol compound. Due to a change in EPA regulations in the early 1990's, the additive formulation was changed to diethylene glycol monomethyl ether. This new formulation has no anti-microbial properties.

The most recent data from the IATA fuel microbiology community indicates that under the very best of circumstances, DiEGME (diethylene glycol monomethyl ether) can only slow the growth of microorganisms by about 40%. Again, that's best case scenario.

Regardless of how often you operate, its important to regularly perform fuel system analysis. The test kits we recommend are from Conidia Bioscience. They are by far the most popular, accurate and easy to use. These kits are sold through Satair. Based on what you find, treat with an approved biocide.

There are only 2 biocides approved for use in aviation globally - Biobor JF and Kathon FP 1.5. Biobor JF has been the standard for many years. Its safe and easy to use. Kathon FP 1.5 is an oxidizer and is highly corrosive. I would discourage anyone from putting this product into an aircraft fuel system.
