What effect does exceeding an aircraft's forward CG limit have on its flight characteristics?

• A. Higher stalling speeds and more longitudinal stability
• B. Lower stalling speeds and less controllability
• C. Higher stalling speeds and less longitudinal stability
• D. Lower stalling speeds and increased stability

Answer: (A)

Exceeding an aircraft's forward center of gravity (CG) limit significantly affects its flight characteristics, particularly in terms of stalling speeds and longitudinal stability. When the forward CG limit is exceeded, the aircraft tends to exhibit higher stalling speeds. This is because a forward CG requires the aircraft to have a greater angle of attack to achieve level flight, thereby increasing the angle at which stall occurs.

Additionally, longitudinal stability is enhanced with a forward CG. A more forward CG position allows the aircraft to return to level flight more effectively when disturbed, contributing to a stable flight behavior. This means that the aircraft will be more resistant to pitch changes and easier to control in the nose-up and nose-down scenarios.

Therefore, the correct answer accurately reflects that exceeding the forward CG limit leads to higher stalling speeds and increased longitudinal stability, which is essential for understanding and managing aircraft performance during flight.
