How can fuel contamination affect aircraft performance?

Fuel contamination can significantly disrupt engine performance because the presence of impurities or foreign substances in fuel can lead to a variety of operational issues. Contaminants such as water, dirt, or microbial growth can cause problems like clogging fuel filters, disrupting the fuel's ability to ignite, or leading to uneven fuel flow. This can result in reduced power output, engine misfiring, or even engine failure, which directly impacts the aircraft's overall efficiency and safety. Maintaining clean fuel is essential for ensuring that all engine components function optimally, making it critical for safe and reliable aircraft operation.
