Soar to New Heights with the 2025 Commercial Pilot License (CPL) Practice Exam – Ready for Takeoff!

Flaps significantly enhance the aerodynamic performance of an aircraft during critical phases of flight, particularly during takeoff and landing. When deployed, flaps increase the surface area of the wing and alter its camber, which leads to a substantial increase in lift, especially at lower airspeeds. This capability allows an aircraft to take off and land at slower speeds, which in turn shortens both takeoff and landing distances.

For takeoff, flaps provide additional lift at lower speeds, permitting the airplane to become airborne sooner and require less runway length. During landing, flaps allow the aircraft to approach at slower speeds while maintaining control, resulting in a shorter landing distance required before safely coming to a stop.

The other factors mentioned do not apply correctly to the effects of flaps on aircraft performance. For instance, flaps do not increase stall speed; rather, they enable the aircraft to fly at lower speeds without stalling for takeoff and landing. They also do not significantly improve climb rates; in fact, while flaps can assist with lift at slower speeds, their deployment during climbing may actually reduce climb performance due to increased drag. Additionally, flaps do not reduce lift during cruise; they are typically retracted during this phase to minimize drag
