Leading edge slats serve the same purpose as slots, the difference being that slats are movable and can be retracted when not needed.
An easy explanation on what these surfaces of control do in an airplane.
Moving the flaps aft toward the tail and the slats forward increases the wing area.
During takeoff and landing, the flaps on the back of the wing extend downward from the trailing edge of the wings.
If it is fixed, then it may appear as a normal part of 33.
Slots and slats permit a new boundary layer to start on the main wing portion, eliminating the detrimental effect of the initial adverse gradient.
Some aerofoils also have slots which allow airflow This link here gives a brief explanation on the difference between a leading edge slat AND a leading edge flap.
The difference of them to slats are that slats are extended from the top surface of the wing, and a Kr眉ger flap is extended from the lower surface of the wing.
The inboard LE Devices are the LE FLAPS and they fully extend at TE Flaps 1 So are in transit only from 0 to 1.
The Original wing without the slats has a full-rounded, and seemingly blunt, leading edge.
Our best judgement was to go to the modified slotted flap and hinge it below the bottom surface of the wing.

On some airplanes, leading edge slats have been automatic in operation, deploying in response to the aerodynamic forces that come into play during a high angle of attack.
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.
Guys, there is a difference between a flap and a slat, the flap can usually be found at the trailing edge of the wing, whilst the slat is usually located at the leading edge of the wing.
Leading-edge devices, such as Krueger flaps and slats, permit the wing to operate at a higher AOA before it stalls by delaying the flow separation.

The Overhead LE DEVICES display is showing both the LE Flaps and LE Slats.
The slat serves three purposes.
The wings with slats, most anyhow, have VGs.
Airplane Slots Slots are a cleverly designed gap in the wing or flap and are used primarily to enable the wing to fly at read more angles of attack.
Current Boeing aircraft, and many others, use this design between the fuselage and closest engine, where the wing is thickest.
The LE flaps are extended whenever the TE flaps are not up.

The reason is that a slat is simply a flap on the leading edge of a wing rather than the trailing edge.
The CH-701 uses both trailing edge and leading edge devices.
They've always referred to them as slats and talk about the difference the nozzles in the stats made.
Wing trailing-edge devices evolved from plain flaps to Fowler flaps with single, double, and even triple slots.

When extended they alter the airflow so the wing can produce more lift at lower speed.
In general, lower flap settings give you more lift, and then as you use higher flap settings you get more drag.
This effectively alters the shape of the wing, allowing it to divert more air, and thus create Jan 14, 2015 路 Without going into the pros and cons, I will initially probably not install the slats.

Slots may be found placed slightly aft of a wing leading edge fixed slotbetween a leading edge slat and the wing leading edge or between trailing edge flap segments on a multi-segment trailing edge flap system such as Fowler flaps.
They increase the angle of attack of the wing.
The problem with it is that it gives you a very high attitude angle during descend and icing formation can occur on this area.
On the other hand the primary role of slats distinct form LE flaps is to control the airflow over the wing, specifically to delay flow separation, and as such don't directly contribute lift themselves but allow the main wing to operate at a higher angle of attack before it stalls.

See Oxfd POF manual page 8-8?
The Kruger flap is a fairly basic device that just click for source forward from below the leading edge to divert airflow over the top surface.
On the trailing edge, the CH-701 uses flaperons, or a combination flaps and ailerons.
The simplest flap is just double slotted fowler flaps flap that turns downward from the trailing edge of the wing, thereby increasing the curvature of the wing, which leads to more lift being generated.
Wing leading edges evolved from fixed leading edges to a simple Krueger flap, and from fixed, slotted leading edges to two- and three-position slats and variable-camber VC Krueger flaps.
As a adverb slap The next time someone asks you about flaps, not only can you list off the 4 types, you can tell them how each of the flaps actually work.
It will in no way be an in depth effort.
Slats are aerodynamic surfaces in the leading edge, which when deployed, allows the wing to operate at higher angle of attack.
The whole leading edge would have to move, without destroying the air flow over the wing.
YESthere is such a thing as a leading edge flap.
This is commonly used on airliners.
Used on the Trident in the 60s and now inboard on the A380.
Many flaps are also Fowler flaps, which not only pivot down, they also slide out, increasing the total area of the wing.
A slat is a small auxiliary aerofoil, placed along the leading edge of the main aerofoil section, able to move forwards or backwards thus opening or closing the gap called a slot.
I don't mean to sound so contrarian but they should pay attention to the gap between the leading edge of that new flap and the trailing edge of the wing.
