Planes are made of light materials because of the four basic elements of flight. Weight, drag, thrust and lift.
Because it takes some sort of power to produce thrust, which intern helps to make lift. Weight and drag are the negative feedback to this reaction. In order to overcome this negative feedback you need more thrust and more lift.
The lighter the plane is, and the smoother the surface is, the more easily it can produce lift. Since we know that in level flight:
lift= weight and thrust = drag
In order for a plane to climb, or begin flight, thrust is needed to produce the airflow over the AIRFOILS (wing, or blades, in other words surfaces for flight) as the velocity of the air increases, the pressure decreases. High pressure systems seek Low pressure systems.
Essentially, a wing is a device that separates air. Because of the shape of it:
Flat bottom and curved top.
The air has further to travel over the top of the wing, and air is a fluid, and fluids don't like to be compressed. This phenomenon causes the air to travel faster over the top.
According to Bernoulli's principle, Higher velocity=lower pressure and higher pressure= lower velocity.
Airplanes are designed to be a more time efficient way of travel.

What materials are light bulbs made of?
Light bulbs are typically made of glass, metal, and a filament made of tungsten.
What materials are light bulbs made out of?
Light bulbs are typically made out of glass, metal, and a filament material such as tungsten.
What material are planes made of?
Most of the frame or body of the airplane is made of aluminum. Aircraft grade aluminum is strong and light - even lighter than titanium. It is interesting to note that early Russian MIG fighter jets had a chassis - called an "airframe" - made entirely of steel. Some other aircraft parts such as engine pistons are made of materials such as steel and the electrical wiring is copper. Some aircraft engines are made of magnesium for very light weight. The drawback to magnesium is its flammability and difficulty in putting out a magnesium fed fire. Of course other parts such as windows may be Lucite or Plexiglas, and some interior parts are other common materials such as leather, glass and various plastics.
Three types of materials that interact with light?
transparent, translucent, and opaque. All 'materials' (i.e. made of matter) interact with em wave energy (which includes light). Humans can detect some but not all of those interactions.
What are materials that transmit and scatter light called?
Materials that transmit light are called transparent materials, while materials that scatter light in various directions are called translucent materials. Materials that do not allow light to pass through are called opaque materials.
What are planes made off?
Planes are usually made of pretty much aluminum as well as other lightweight composite materials. They are built to be strong and lightweight.
What are the two nonflammable materials that airplanes are made from?
The steel in the screws and the polycarbonate in the windshields? All the other materials planes are made from are at least combustible, including aluminum and composites.
Is making a plane with metal possible?
Yes it is possible. All planes are made out of a light plastic or light metal.
What material are used for plane body?
Aluminum for most jet commericial planes. New planes like the Boeing 787 and Airbus A350 are made of composite materials.
What materials are light bulbs made of?
Light bulbs are typically made of glass, metal, and a filament made of tungsten.
What material are sarongs made of?
The materials that sarongs are made of are Rayon, Chiffon, and cotton. These materials used are all light weight .
What materials are light bulbs made out of?
Light bulbs are typically made out of glass, metal, and a filament material such as tungsten.
What materials is the Austin Mini made from?
steel light sheets that's why they rust but are light weight
Why are planes not made from copper alone?
Planes are not made from copper alone because copper is heavy, can be prone to corrosion, and lacks the necessary strength and stiffness required for structural components of an aircraft. Instead, airplanes are made from lighter and stronger materials such as aluminum, titanium, and composite materials to ensure optimal performance and safety.
What is the name of a Parisian airplane?
Airplanes made in France include EADS Airbuses and EADS Socata light planes.
Why are hoods of car usually made of light materials?
They aren't always made of light materials. For example a 57 Desota, very heavy hood. Depends on the manufacturer, the hood is usually made out of the same material as the rest of the car.
