What is the maximum fuel temperature for takeoff?

The maximum fuel temperature for takeoff is set at 49°C. This limitation is crucial in ensuring the safety and performance of the aircraft. Higher fuel temperatures can lead to decreased fuel density, which may affect engine performance and fuel flow. Maintaining the fuel within the specified temperature range helps to prevent issues such as vapor lock and ensures optimal combustion efficiency.

In addition, exceeding this maximum fuel temperature can lead to potential damage to the fuel system and engines, as well as a negative impact on overall operational reliability. Therefore, adhering to this limitation is an essential part of preflight checks and ensures compliance with safety regulations.
