Why the flaps and slats are extended during take off and landing?

Answer: The slats on the leading edge of the wing allow the airplane to take off and land at lower speeds. When extended they alter the airflow so the wing can produce more lift at lower speed. For high-speed flight, they are retracted to reduce drag.

What is the difference between slats and flaps?

The part on the leading edge is called a slat, while the part on the trailing edge is called a flap. The flaps and slats move along metal tracks built into the wings. In addition, the large aft-projected area of the flap increases the drag of the aircraft. This helps the airplane slow down for landing.

Can you takeoff without flaps?

Yes take-off without flaps is possible. The Airbus A300 and Boeing 767 are approved for such take-offs and it is being done regularly. It results in a better climb gradient, especially with one engine out.

How does slot work in aircraft wing?

A leading-edge slot is a spanwise gap in each wing, allowing air to flow from below the wing to its upper surface. In this manner they allow flight at higher angles of attack and thus reduce the stall speed.

How do flaps work on an airplane?

Wing flaps change the shape of the airplane wing. They divert the air around the wing as necessary. The setting of the flap determines whether they are used to increase lift (as on takeoff) or increase drag (used on landing.) This allows the pilot to take a steeper angle of attack to the landing field.

How do the flaps on a plane work?

The flaps and slats move along metal tracks built into the wings. Moving the flaps aft (toward the tail) and the slats forward increases the wing area. Pivoting the leading edge of the slat and the trailing edge of the flap downward increases the effective camber of the airfoil, which increases the lift.

What is the purpose of a slat on a plane?

Pivoting the leading edge of the slat and the trailing edge of the flap downward increases the effective camber of the airfoil, which increases the lift. In addition, the large aft-projected area of the flap increases the drag of the aircraft. This helps the airplane slow down for landing.

What is the difference between a flap and a slat?

The part on the leading edge is called a slat , while the part on the trailing edge is called a flap. The flaps and slats move along metal tracks built into the wings. Moving the flaps aft (toward the tail) and the slats forward increases the wing area.

Why do aircraft have different flap angles?

Large flap deployment angles also make the aircraft more susceptible to gusts. On windy days it is common in a light aircraft to fly the approach and landing at a reduced flap angle to improve control authority in these conditions. There are many variations of trailing edge flap in use on modern aircraft today.
