What is the bulk fuel freezing point temperature?

The correct answer is -40°C, which serves as the bulk fuel freezing point for the CRJ 200. This temperature indicates the point at which the fuel can start to experience formation of solid particulates, which can lead to potential fuel system blockages and malfunctions. Understanding this limitation is crucial for flight operations, especially in cold weather conditions, as it ensures that fuel remains suitable for engine operation and does not cause failures or hazardous situations during flight.

The specification of -40°C as the freezing point is aligned with industry standards for Jet A and Jet A-1 fuels, which are commonly used in commercial aviation. Ensuring that the fuel temperature does not drop below this point is vital for maintaining aircraft performance and safety. This knowledge assists pilots and ground operations in making informed decisions regarding fuel management during pre-flight and during operations in low-temperature environments.
