What occurs during the inspection of the flight control system of an airplane equipped with differential-type aileron control?

In a differential-type aileron control system, the design allows for each aileron to have a greater up travel than down travel. This is intentional and serves a critical aerodynamic purpose. When the pilot initiates a roll by deflecting the ailerons, the aileron on the rising wing (the up aileron) deflects more and creates a greater angle, which increases lift on that wing. Conversely, the aileron on the descending wing (the down aileron) deflects less, which helps to reduce drag and adverse yaw.

This differential movement contributes to a more balanced and controlled roll response, ensuring that the aircraft does not yaw excessively in the opposite direction of the roll, which can occur with equal aileron travels. In essence, having greater up travel enhances the efficiency and effectiveness of the aileron system during flight maneuvers, making it a vital aspect of flight control.

The other options describe scenarios that do not accurately represent the characteristics of differential aileron control systems. Option indicating that both ailerons move in unison lacks the distinctiveness of roll control provided by differential movement, while stating that the ailerons are fixed implies a complete lack of mobility, contradicting
