What is the minimum fuel temperature for takeoff?

The minimum fuel temperature for takeoff is +5°C. This limitation is crucial for the safe operation of the aircraft because fuel can begin to gel or function improperly at lower temperatures, which can lead to engine performance issues or fuel system blockages. Keeping the minimum fuel temperature at +5°C ensures that the fuel remains fluid, maintaining optimal engine performance and reducing the risk of adverse effects on fuel flow.

Setting this threshold is designed to provide a safety margin in various operational conditions, ensuring that pilots are aware of the risks associated with cold fuel temperatures. Proper fuel management is essential, especially when the aircraft is operating in cold weather conditions, to mitigate the potential for fuel system failures during critical phases of flight such as takeoff.
