Why should you switch fuel tanks during flight in the DA20-C1?

• A. To maintain fuel balance and comply with limitations
• B. To achieve better cabin lighting
• C. To reduce the need for air traffic control
• D. To quickly empty a tank for weight transfer

Answer: (A)

Switching fuel tanks during flight is done to keep the airplane within its weight and balance limits as fuel is burned. The DA20-C1 uses two wing tanks, and if you stay on one tank, the remaining fuel becomes unevenly distributed, causing a roll tendency and shifting the center of gravity toward the heavier wing. By alternating tanks, you maintain a more balanced load, which helps keep handling predictable and ensures you stay within the approved CG range. It also helps prevent fuel starvation by using both tanks rather than relying on a single one. Other options don’t fit the situation: switching won’t improve cabin lighting, won’t reduce dependence on air traffic control, and intentionally emptying a tank for weight transfer is not a safe or recommended practice.
