What is the maximum fuel temperature for the CRJ 200?

The maximum fuel temperature for the CRJ 200 is 49°C. This limitation is essential for ensuring the proper operation of the aircraft's fuel system and engines. Fuel temperature significantly influences fuel viscosity and, in turn, affects fuel flow and the efficiency of the fuel pumps. Keeping the fuel temperature within specified limits prevents issues such as vapor lock and ensures that the fuel quality remains suitable for combustion in the engines.

In ground operations and at altitude, exceeding the maximum fuel temperature can increase the risk of engine performance issues, potentially leading to abnormal engine operation or damage. Adhering to this specification is crucial for safe flight operations and to maintain the integrity of the aircraft's engines.
