Freezing Point: Under Specified conditions, aviation fuel is cooled to form solid hydrocarbon crystals. And then the fuel is heated up. The lowest temperature when the hydrocarbon crystals disappear is the freezing point of aviation fuel.
The meaning and use of freezing point: The freezing point of aviation fuel is to ensure no solid hydrocarbon crystal in the fuel. The temperature in the aircraft fuel tank usually decreases during flight, and the degree of decrease depends on the flight speed, altitude, and flight duration. Therefore, the freezing point of the fuel
