What occurs when the center of pressure moves forward?

• A. It causes the aircraft to ascend rapidly
• B. It can result in a nose-up moment, affecting stability
• C. It stabilizes the aircraft for cruising
• D. It decreases drag significantly

Answer: (B)

When the center of pressure moves forward, it alters the aerodynamic forces acting on the aircraft, specifically the lift and drag characteristics. The center of pressure is the point on an airfoil where the total aerodynamic force is considered to act. If this point shifts forward, it generally creates a moment that tends to pitch the nose of the aircraft upwards relative to its flight path. This nose-up moment can affect the aircraft's stability; specifically, it might lead to an increase in the angle of attack, which can enhance lift but also risks a stall if the angle becomes too steep. The repositioning of the center of pressure forward may change how the aircraft responds to control inputs, making it feel different to the pilot. Understanding this dynamic is important for maintaining aircraft control and ensuring stability during flight.
