What is the role of flaps in the Cessna 172?

Flaps play a significant role in the performance of the Cessna 172, particularly during critical phases of flight such as takeoff and landing. When deployed, flaps increase the wing's camber, which enhances lift at lower airspeeds. This increase in lift allows the aircraft to take off and land at slower speeds, effectively decreasing the stall speed. This capability is crucial for ensuring safe operations, especially in shorter runways or when flying in conditions requiring slower speeds.

The use of flaps can be seen during approach when pilots extend them to maintain lift while reducing airspeed, enabling a stable descent. Similarly, they assist in lowering landing speeds, enhancing control and safety as the aircraft prepares to touch down.

While there are other functions and aerodynamic effects at play, particularly related to drag, the primary function of flaps in this context is focused on their ability to increase lift and reduce stall speed.
