What type of ailerons does the Arrow feature?

The Arrow features differential ailerons, which are designed to improve the roll response of the aircraft while minimizing adverse yaw. In a typical setup with differential ailerons, one aileron moves up more than the corresponding aileron moves down. This design helps to counteract the yawing motion that can occur when an aileron is deflected. As the aileron on one wing moves up, it reduces lift on that wing, while the aileron on the opposite wing moves down, increasing lift there. This differential movement leads to a more efficient roll response and helps keep the aircraft coordinated during maneuvers, enhancing overall handling characteristics.

In contrast, conventional ailerons typically operate in a one-to-one relationship without this differential movement, potentially leading to more pronounced adverse yaw. Frise ailerons have a similar function but incorporate a design that increases drag on the wing that is being raised, further reducing adverse yaw. Flaperons serve as both flaps and ailerons, aiding in roll control and increasing lift at lower speeds, which is not applicable to the Arrow's design. The use of differential ailerons in the Arrow exemplifies modern airplane design priorities focusing on control and safety.
