Final answer:
Fowler flaps increase both camber and wing area in aircraft.
Step-by-step explanation:
The flaps that increase both camber and wing area are called fowler flaps. These flaps are commonly used in aviation to increase the lift and maneuverability of the aircraft during takeoff and landing. Fowler flaps extend both downwards and backwards, increasing the wing's surface area and changing the shape of the wing to generate more lift.
