What is the freezing point of Jet A bulk fuel?

Explanation:
Jet A is a kerosene-based aviation fuel, and the temperature at which it begins to solidify is the freezing point. In aviation fuel specifications, Jet A has a maximum freezing point of -40°C, meaning the fuel should remain liquid above this temperature. If the fuel cools to -40°C or below, wax crystals can form and start to clog filters and restrict flow, which is why the -40°C mark is the critical limit. This is why -40°C is the correct answer for the freezing point of Jet A bulk fuel. Note that Jet A-1 has a lower freezing point (around -47°C), which is why some systems use Jet A-1 in colder regions; the question specifically asks about Jet A bulk fuel.
