Final Answer:
The system associated with differential control is C. aileron.
Step-by-step explanation:
Differential control in aviation is primarily linked to the ailerons, which are control surfaces on the wings of an aircraft responsible for roll control. The ailerons work differentially, meaning that when one aileron is raised, the other is lowered. This asymmetrical movement helps in creating a rolling motion, allowing the aircraft to bank left or right.
The concept of differential control is based on the principle of inducing a greater lift on one wing while reducing lift on the other during a turn. This is achieved by deflecting the ailerons in opposite directions. The increased lift on one side assists in the banking maneuver, providing the necessary control to execute turns smoothly.
Therefore, ailerons are crucial components of the differential control system, allowing pilots to maneuver aircraft effectively.
