What type of flaps does the aircraft have?

Single slotted flaps are designed to enhance an aircraft's lift and improve its stall characteristics during low-speed flight. They work by creating a slot between the wing and the flap, which allows high-energy air from the lower surface of the wing to flow over the upper surface of the flap. This airflow helps maintain lift at higher angles of attack, delaying stall and providing better control during critical phases of flight, such as takeoff and landing.

In contrast, plain flaps are simpler in design and don't feature any slots, which limits their effectiveness in delaying stall. Split flaps are characterized by a part of the flap that extends downward while another part remains on the wing, also affecting airflow but lacking the benefits of the additional slot. Double slotted flaps, meanwhile, offer even more lift augmentation by featuring two slots. Although each type has its unique characteristics, single slotted flaps balance complexity with performance enhancement effectively for many general aviation airplanes. Understanding these specific functionalities aids in recognizing why single slotted flaps are applicable to the question.
