What Flaps and Slats Do

During takeoff and landing, parts of the wing move into new positions.

Two of the most important are flaps and slats.

✈️ 1. They Change the Wing for Low-Speed Flight

At cruising speed, the wing is set up for efficiency.

But during takeoff and landing, the plane flies more slowly and needs extra lift.

Flaps and slats help the wing perform better in those low-speed situations.

⬅️ 2. Flaps Extend From the Rear of the Wing

Flaps are usually located along the back edge of the wing.

When extended, they help:

• increase lift
• increase drag
• allow slower, safer approach and departure speeds

They are especially useful during landing.

➡️ 3. Slats Extend From the Front of the Wing

Slats are on the leading edge, or front of the wing.

They help the wing handle higher angles of attack more effectively, especially at lower speed.

This improves airflow behavior when the aircraft needs extra lift.

🛫 4. They Help During Takeoff and Landing

For takeoff, flaps and slats help the aircraft leave the ground at lower speed.

For landing, they help the plane fly slowly and steadily while also creating useful drag.

👉 They make the wing more suitable for the slowest phases of flight.

✨ What It Means

Flaps and slats are part of how one wing can handle very different jobs:

• efficient cruise
• slow takeoff
• controlled landing

Without them, modern airliners would need very different wing compromises.

💡 Simple Way to Think About It

Flaps and slats are like:

temporary wing upgrades... used when the aircraft needs extra help at lower speed.

🟢 Quick Fact

The exact flap setting for takeoff or landing depends on aircraft type, runway conditions, and performance needs.

---

Flaps and slats may move quietly in the background - but they play a major role in making takeoff and landing safer and more manageable.
