The other difference is the mandatory addition of an antistatic additive to Jet A-1 fuel. Jet A and Jet A-1 fuel trucks and storage tanks, as well as plumbing that carries them, are all marked "Jet A" or "Jet A-1" in white italicized text within a black rectangle background, adjacent to one or two diagonal black stripes.

Flight altitude affects engine efficiency. Jet-engine efficiency increases at altitude up to the tropopause, the temperature minimum of the atmosphere; at lower temperatures, the Carnot efficiency is higher. [111] Jet engine efficiency is also increased at high speeds, but above about Mach 0.85 the airframe aerodynamic losses increase faster.
Jet fuel is a gas turbine fuel used in propeller and jet fixed-wing 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.
The main petroleum component used in blending avgas is alkylate, which is a mixture of various isooctanes. Some refineries also use reformate.All grades of avgas that meet CAN 2–3 [further explanation needed], 25-M82 [further explanation needed] have a density of 6.01 pounds per US gallon (720 g/L) at 15 °C (59 °F).
An aviation biofuel (also known as bio-jet fuel, [89] sustainable aviation fuel (SAF) or bio-aviation fuel (BAF) [90]) is a biofuel used to power aircraft. The International Air Transport Association (IATA) considers it a key element in reducing the environmental impact of aviation. [91]
However, that's still a piddling amount compared to the aviation sector's overall thirst for fuel. (For reference, U.S. airlines used 1.41 billion gallons of fuel in January 2023 alone, according ...
