Balance Your Fuel

Gemini Sparkle

Key Takeaways:

  • Fuel imbalance is a critical safety concern, potentially affecting aircraft handling and causing damage, even if sufficient fuel is onboard.
  • Pilots must regularly monitor fuel gauges (e.g., every 30 minutes) and utilize alerts to maintain an even fuel distribution across tanks.
  • Actively manage fuel by switching tanks every 30 minutes, or by burning from individual tanks to correct imbalances, even in aircraft with a "both" selector, while understanding specific fuel system limitations.

Ensuring that you are carrying enough fuel to complete your planned flight is not the only fuel-related concern that you should keep in mind as you fly. While a fuel imbalance may not cause you to make an emergency landing, it could mean the difference between having a nice smooth touchdown and potentially causing some damage to the airplane.

Check your fuel gauges every 30 minutes or so to make sure the amount of fuel in each tank is relatively even. If you are fortunate enough to fly with technologically advanced avionics, you likely have the option to set an alert or message that will remind you to glance at your fuel gauges. If your avionics don’t have alert capabilities, you may want to set some other type of alarm as a reminder.
