Final answer:
The forces acting on an aircraft include the center of gravity (CG) and flight characteristics. The center of gravity is the point where the weight of the aircraft is concentrated, while flight characteristics refer to the aerodynamic forces affecting the aircraft's performance. The center of gravity plays a crucial role in aircraft stability and balance.
Step-by-step explanation:
It determines the stability and balance of the aircraft. Flight characteristics refer to the aerodynamic forces that affect the aircraft's performance, such as lift, drag, and thrust.
The center of gravity is an important factor in aircraft design and operation. It is typically located near the wings to ensure stability and control. If the center of gravity is too far forward or backward, it can affect the aircraft's maneuverability and stability. Pilots need to be aware of the center of gravity limits to maintain safe and efficient flight.
