What is the type of ailerons used in the aircraft?

The correct answer to the question about the type of ailerons used in the aircraft is actually "Frise ailerons."

Frise ailerons are designed with a specific shape that helps to improve aerodynamics and control. When a Frise aileron deflects downward, the leading edge protrudes into the airflow, increasing lift on that wing and contributing to effective roll control. This design helps counteract adverse yaw, improving the aircraft’s handling and stability during turns.

In contrast, hinged ailerons simply pivot along a hinge point but do not incorporate the aerodynamic advantages provided by the Frise design. Forward spar ailerons and slotted ailerons refer to different mechanisms or designs that are used for controlling airflow and enhancing lift, but they do not share the same functional characteristics as Frise ailerons. Understanding these distinctions is crucial for comprehending aileron functionality and performance in various flight conditions.
