What is the minimum fuel temperature allowed for takeoff in the CRJ 900?

The minimum fuel temperature allowed for takeoff in the CRJ 900 is -37°C. This temperature is established to ensure that the fuel remains in a suitable state for proper atomization and combustion during engine operation. At temperatures above this limit, the fuel can exhibit characteristics that maintain optimal performance and prevent issues such as wax formation or fuel filter plugging, which can result from excessively cool fuel.

Adhering to this limitation is crucial for maintaining engine reliability and efficiency, especially during cold-weather operations. Operating outside this temperature range can jeopardize engine performance and safety. Therefore, pilots must carefully monitor fuel temperatures and follow the established limitations to ensure safe operational practices.
