The fairings that cover the flap tracks are sometimes called "canoes"
due to their general appearance.

I saw a display of the Airbus A-380 "canoes" once, they were *massive*.

Right. The flap actuating mechanism is very complex, and large. It allows
the flaps to actuate back, and at a downward angle, with slots between each
section of the flaps. This allows the wing to grow in size (with the flaps
extended), and increase the lift coefficient of the wing with the flap
extended, more than just a plain pivoting flap like general aviation planes
usually have.
