Humidity isn’t just uncomfortable—it can be dangerous for your aviation fuel system. Fuel tanks face increased risks of contamination, corrosion, and costly downtime in areas where the air is heavy with moisture. That’s why consistent monitoring is more than just good practice—it’s essential.
1. Moisture Means Condensation
When warm, humid air surrounds a cooler fuel tank—especially above ground—condensation forms inside the tank. Even small amounts of water can compromise fuel quality, damage components, and encourage microbial growth.
Tip: Monitor tank temperatures and perform water draws regularly, especially after temperature fluctuations or high-humidity days.
2. Microbial Growth Accelerates
Humidity plus water equals a perfect breeding ground for microbes. Bacteria and fungi feed off water and hydrocarbons, creating sludge that clogs filters and corrodes tank walls, leading to serious system failures.
Tip: Schedule frequent inspections during humid months and consider periodic biocide treatments to stay ahead of microbial growth.
3. Corrosion Risks Increase
Even a trace amount of water can lead to internal corrosion. Over time, corrosion can degrade tank integrity and result in fuel leaks or expensive replacements.
Tip: Monitor tank bottoms for rust or residue, and don’t ignore signs of filter clogging—these may be indicators of internal corrosion.
4. Fuel Quality Can Be Compromised
Humidity-related water intrusion can cause fuel to separate or degrade faster, especially in jet fuels and diesel blends. Degraded fuel puts your equipment and compliance at risk.
Tip: Use tank monitoring systems that alert you to water levels, temperature changes, and product separation in real time.
5. Monitoring Protects More Than Fuel
Consistent tank monitoring doesn’t just protect fuel—it protects your entire operation. Early detection of water buildup, microbial activity, or changes in pressure can prevent larger issues and reduce long-term costs.
Tip: Pair digital tank monitoring with routine manual inspections to ensure nothing slips through the cracks.
