How does a forward centre of gravity affect aircraft stability?

• A. Increases longitudinal stability.
• B. Decreases longitudinal stability.
• C. No effect on stability.
• D. Only becomes evident at low speeds.

Answer: (A)

A forward center of gravity significantly influences an aircraft's longitudinal stability by increasing it. When the center of gravity is located forward, it causes the aircraft to be more stable in pitch. This stability stems from the fact that if the aircraft experiences a pitch disturbance, a forward center of gravity creates a moment that tends to return the nose of the aircraft back to its original attitude, promoting a self-correcting behavior. In practical terms, a forward center of gravity means that the aircraft tends to resist changes to its pitch attitude, making it easier for pilots to control during flight. This enhanced stability is particularly beneficial during certain phases of flight, like takeoff and landing, where consistent control is critical. Understanding the concepts of aircraft stability is vital for flight safety and performance, as they directly impact the handling characteristics and ease with which pilots can manage the aircraft.
