Where are the leading edge slats located?

They alter the shape of an airplane’s wing to help it produce more lift at low airspeeds. Slats are found on the wing’s leading edge, and they move forward to increase the camber of the wing.

Does a 737 have leading edge flaps?

The LE devices (figure 1.2) on the Boeing 737 consist of the leading edge flaps and slats and are both located on the leading side of the wing and are hydraulically powered by hydraulic system B. The commands for the LE flaps and slats come from the TE flap system.

Does the 737 have slats?

The 737-1/2/3/4/500 aerofoil is made up of four specially designed Boeing aerofoil sections splined into one smooth surface as follows: Short field take-off performance was achieved by Krueger flaps and slats. Short field landing performance came from the triple slotted flaps.

What is a 737 slat track?

Slat tracks are located on the leading edge of a Boeing 737’s wings and are used to guide the movement of panels known as slats. These panels provide additional lift during takeoff and landing.

Where are slats located?

wings
Slats are extendable, high lift devices on the leading edge of the wings of some fixed wing aircraft. Their purpose is to increase lift during low speed operations such as takeoff, initial climb, approach and landing.

What is the difference between leading edge flaps and slats?

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.

What are leading edge flaps?

Leading edge flaps, like trailing edge flaps, are used to increase both the lift coefficient and the camber of the wing. This type of leading edge device is frequently used in conjunction with trailing edge flaps and can reduce the nose-down pitching movement produced by the latter.

What is speed trim on a 737?

boeing-737 trim. The Speed Trim System (STS) is a speed stability augmentation system designed to improve flight characteristics during operations with a low gross weight, aft center of gravity and high thrust when the autopilot is not engaged.

How do Krueger flaps work?

Krueger flaps are mounted on the bottom surface of the wing and are hinged at their leading edges. Actuators extend the flap down and forwards from the under surface of the wing thus increasing the wing camber which, in turn, increases lift.

What leading edge slats do?

Slats are extendable, high lift devices on the leading edge of the wings of some fixed wing aircraft. Their purpose is to increase lift during low speed operations such as takeoff, initial climb, approach and landing.

Why are leading edge slats used?

What is the purpose of a leading edge slot?

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.

What happens if a leading edge slat fails?

Complete failure of a leading edge slat would not result in loss of the plane, according to the FAA, but “a risk remains that a failed part could lead to aircraft damage in flight.” A total of 55 of the potentially affected aircraft are located within the U.S. We were unable to load Disqus.

Are there any issues with the 737 MAX?

Boeing is recommending relevant operators of 179 737 MAX aircraft and 133 737 NG aircraft to check the slat track assemblies before putting them back into the air, though it thinks the number of airplanes fitted with the bad parts is considerably smaller: 20 MAXs and 21 NGs.

How are flaps and slats affect the wing area?

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. In addition, the large aft-projected area of the flap increases the drag of the aircraft.

Where are the flight controls located on a 737?

This will give limited changes to the vertical flight path from the spoilers to assist the approach and landing if the normal elevator system jams. The control panel is located on the Aft Overhead Panel, even if it is switched on it will only be active when the flaps are 1 or greater.
