What happens to the center of gravity when fuel is burned during flight?

• A. It moves forward
• B. It moves aft
• C. It stays the same
• D. It rotates about the vertical axis

Answer: (B)

When fuel is burned during flight, the center of gravity moves aft. This occurs because, as fuel is consumed, the overall weight of the aircraft decreases, and the remaining fuel typically is located toward the center or toward the tail of the aircraft. As the aircraft gains altitude and the fuel burns off, the distribution of weight shifts to the rear, leading to an aft movement of the center of gravity. Maintaining the correct center of gravity is crucial for safe flight operations. An aft center of gravity can lead to decreased stability and control of the aircraft, potentially making it difficult for the pilot to manage the aircraft's pitch and handling characteristics. It is vital for pilots to monitor fuel levels and understand how the burning of fuel affects the center of gravity to ensure the aircraft remains within safe operating limits throughout the flight.
