Final answer:
A rearward center of gravity on an aircraft decreases stability and increases maneuverability.
Step-by-step explanation:
A rearward center of gravity on an aircraft can have a significant effect on its flight characteristics. Specifically, it decreases stability and increases maneuverability.
When an aircraft has a rearward center of gravity, it becomes more prone to pitching and yawing motions. This can make the aircraft less stable, as it may have a tendency to pitch up or down unexpectedly.
On the other hand, a rearward center of gravity can also make the aircraft more maneuverable. It allows for quicker and more agile movements, which can be desirable in certain flight maneuvers.
