Final answer:
An aircraft with the Center of Gravity at the most aft limit may experience reduced stability, leading to increased pitch sensitivity and potential control difficulties.
Step-by-step explanation:
When the Center of Gravity (C of G) of an aircraft is at the most aft (rearward) limit, the stability of the airplane may be negatively affected. Aft C of G positions tend to make an airplane more sensitive to pitch, which can lead to difficulty in control, as the aircraft may become more prone to pitching moment changes caused by turbulence or control inputs. Should the C of G move even further aft, beyond the limits, the airplane could become dynamically unstable, which is a hazardous condition that can lead to a loss of control.
In summary, an aft C of G may decrease pitch stability; this affects how the aircraft responds to disturbances in flight. For safe operation, aircraft designers and operators establish C of G limits to ensure a suitable balance between stability and controllability.
