Which device is used to make steeper landing approaches?

• A. Flaps
• B. Slats
• C. Spoilers
• D. Ailerons

Answer: (A)

Flaps are high‑lift devices that increase wing camber and effectively the wing’s lift at lower speeds. When extended, they raise the lift coefficient, allowing the airplane to fly slower without stalling. That means you can descend toward the runway on a steeper glide path while still keeping enough lift to maintain safe control. The added drag from flaps also helps control the descent rate during the approach. Slats can also increase lift but are not the primary tool for steepening an approach in normal operations. Spoilers reduce lift to help descent and braking, which doesn’t achieve a steeper approach in the sense of maintaining safe lift at lower speeds. Ailerons control roll, not the approach angle.
