'''Jet fuel''' is a clear to straw-colored fuel, based on either an [[unleaded]] [[kerosene]] (Jet A-1), or a [[naphtha]]-[[kerosene]] blend (Jet B). Similar to [[diesel fuel]], it can be used in either [[Diesel engine|compression ignition engine]]s or [[Gas turbine|turbine engine]]s.<ref name=chevron/>
Jet-A powers modern commercial airliners and is a mix of extremely refined kerosene and burns at temperatures at or above {{convert|49|C}}. Kerosene-based fuel has a much higher flash point than gasoline-based fuel, meaning that it requires significantly higher temperature to ignite. It is a high-quality fuel; if it fails the purity and other quality tests for use on jet aircraft, it is sold to ground-based users with less demanding requirements, such as railroads.<ref>{{cite web |last=U.S. Centennial of Flight Commission |title=Aviation Fuel |url=http://www.centennialofflight.gov/essay/Evolution_of_Technology/fuel/Tech21.htm |access-date=10 May 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120420064213/http://www.centennialofflight.gov/essay/Evolution_of_Technology/fuel/Tech21.htm |archive-date=20 April 2012 }}</ref>

==Production of aviation fuel==
The production of aviation fuel falls into two categories: fuel suitable for [[Gas turbine|turbine engine]]s and fuel suitable for spark-ignition piston engines. There are international specifications for each.
[[Jet fuel]] is a gas turbine fuel used in propeller and jet aircraft and helicopters. It has a low [[viscosity]] at low temperature, has limited ranges of density and [[calorific value]], burns cleanly, and remains chemically stable when heated to high temperature.<ref>{{cite web|author=Air BP |title=Avgas vs Jet Fuel |url=http://www.bp.com/sectiongenericarticle.do?categoryId=4503818&contentId=57639 |access-date=10 May 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120425054146/http://www.bp.com/sectiongenericarticle.do?categoryId=4503818&contentId=57639 |archive-date=25 April 2012 }}</ref>
