Airplanes use a combination of slats and flaps in order to increase lift and increase drag. The slats are located on the leading edge of the wing and the flaps on the trailing edge. Flaps and slats when extended forward and aft increase the wing area which increases lift. When the flaps and slats are further extended they curve downwards increasing the camber of the wing which also increases lift. The greater the lift, the greater the drag. Deploy the flaps a little and lift overcomes the drag, fully extend them and the drag overcomes the lift. For takeoff the flaps and slats may be extended just a few degrees to increase lift. When flaps and slats are fully deployed in landing configuration, the lift is great but so is the drag and this in turn helps to slow down the airplane on decent to land.

Why Is it important to reduce drag?
Reducing drag is important because it increases efficiency, saves energy, and improves performance in various applications such as vehicles, aircraft, and sports equipment. Drag reduction helps to decrease fuel consumption, increase speed, and enhance overall aerodynamic stability.
What are some factors that can cause a rivers speed and discharge to decrease?
Factors that can cause a river's speed and discharge to decrease include reduced precipitation leading to lower water input, increased evaporation, and human activities such as damming that restrict flow. Additionally, changes in land use like deforestation can decrease runoff and thus reduce the speed and discharge of a river.
What are the ways to reduce drag?
To reduce drag, you can streamline the shape of the object, minimize surface roughness, and reduce the frontal area exposed to the flow of air or water. Additionally, reducing speed can also help decrease drag forces.
What is bernoulli's princeiple?
Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. This principle explains how an aircraft's wings generate lift and how a carburetor works in a car engine. It is important in fluid dynamics and aerodynamics.
How is the speed of an aircraft measured?
The speed of an aircraft is measured using an airspeed indicator, which measures the speed at which the aircraft is moving through the air. Groundspeed, on the other hand, is the speed at which the aircraft is moving over the ground and is measured using GPS technology.
How can an aircraft reduce the speed in the air?
during flight aircraft reduce speed by spoiler
What is a rumble device designed to?
The rumble device is designed to - encourage you to reduce your speed - alert you of a hazard approaching
How speed calculated in aircraft?
One way to measure airspeed is to use a device called a pitot tube.
How can you slow a plane down?
there are a couple of ways to slow a plane down. the first is to throttle down, this will help decrease speed. the second is pitch, if you increase the pitch, or raise the nose, you can decrease speed too. most aircraft have a pitch control wheel that raises or lowers the pitch (Nose) of the aircraft. By raising the pitch alittle and throttling down, you will slow the aircraft down really quick.
How in fighter aircraft is instant pressure difference created for lift?
Flaps are used on aircraft to increase the wing area of the plane and therefore increase lift and reduce speed.
What are the uses of a gear train?
Either to increase speed and reduce torque or to decrease speed and increase torque while conserving mechanical energy.
What is an anemoeter?
An anemometer is a device used to measure the speed of wind. It typically consists of a set of cups that spin in the wind, and the speed of rotation is used to calculate the wind speed. It is commonly used in weather stations and on aircraft.
Why Is it important to reduce drag?
Reducing drag is important because it increases efficiency, saves energy, and improves performance in various applications such as vehicles, aircraft, and sports equipment. Drag reduction helps to decrease fuel consumption, increase speed, and enhance overall aerodynamic stability.
How does the wing of an aircraft and runway length related. if we reduce the wing size of any Airbus or Boeing and increase the runway length then what will happen?
If you reduce wing size the aircraft will take longer distance and will have to attain higher ground speed before lift-off.
Does reduction in aircraft speed reduce fuel usage?
If the aircraft's engine thrust is reduced, by reducing the power the engines generate, less fuel will be burned. This said, over the course of a journey, there will be an optimum altitude and speed for an aircraft to fly at in order to burn the least fuel. This calculation will be the result of a number of things, including how heavy the aircraft is, and how the surrounding whether will affect it.
An airplane has a takeoff speed of 80ms which it reaches 35s after starting from rest what is the minimum length of the runway?
Assuming it as passenger aircraft and take-off speed = lift off speedwe have minimum runway length required as 80*35 = 2.8kmIf it is a military aircraft the length will reduce further to minimum unstick speed
What are some factors that can cause a rivers speed and discharge to decrease?
Factors that can cause a river's speed and discharge to decrease include reduced precipitation leading to lower water input, increased evaporation, and human activities such as damming that restrict flow. Additionally, changes in land use like deforestation can decrease runoff and thus reduce the speed and discharge of a river.
