Yes, aviation fuel can freeze, particularly when the temperature drops below its freezing point, which varies depending on the type of fuel. Jet fuel, for example, can start to solidify or wax at temperatures as high as -40°C or lower, which can cause issues with the fuel flow and engine performance.
To prevent aviation fuel from freezing, a number of measures are taken, such as adding anti-freeze additives or blending different types of fuel. Fuel suppliers also often use insulated tanks to store the fuel and employ various heating methods to keep the fuel from getting too cold.
In addition, aircraft systems are designed to prevent fuel freezing, with measures such as fuel heaters, fuel filters, and fuel circulation systems. Pilots are also trained to monitor fuel temperature and adjust their flight plans accordingly to avoid flying at altitudes or in temperatures that could cause fuel freezing.
Overall, while aviation fuel can freeze, precautions are taken to prevent this from happening, and pilots and fuel handlers are trained to recognize and respond to any issues that may arise.
