What can impurities in fuel lead to in aircraft operation?

Impurities in fuel can significantly affect the operation of an aircraft's engine, leading to engine performance issues. Contaminants such as water, dirt, or other foreign substances can cause a variety of problems, including reduced fuel flow, improper combustion, and potential damage to sensitive components within the engine.

When impurities disrupt the fuel system, pilots may experience issues such as decreased power output, rough engine performance, or even engine malfunction. In severe cases, contaminated fuel can lead to engine failure, putting the aircraft at risk during flight. This highlights the importance of using clean, high-quality fuel in aviation to ensure optimal engine operation and overall safety.
