Abstract
A fuel freezing point monitoring device to monitor the freezing point of onboard fuel, especially aircraft fuel. The fuel freezing point monitoring device is capable of monitoring the phase transition or fluidity of the fuel to determine the freezing point of the fuel. The fuel freezing point monitoring device eliminates the freezing point assumption of onboard fuel by actually measuring the freezing point of the fuel. The pilot will have knowledge of the approximate freezing point of the composite onboard fuel and will no longer need to assume a conservative fuel freezing point value. Together with the en-route fuel temperature information provided by existing aircraft sensors, the pilot will have the information to ensure a safe flight and to operate the aircraft efficiently.
