What is the speed of the plane taking off?

Airplane take-off speed

Take-off speed varies from aircraft to aircraft; Each type of aircraft needs an appropriate speed to lift the wings, and it depends on the weight of the aircraft. As speed overcomes weight by generating enough force to lift it, for example: the aircraft “A Boeing 747” flies at a speed of 184 kilometers per hour (296 miles per hour), and various weather factors affect the speed of the plane, because it reduces the movement of the headwind due to the speed of the plane.^[١]

The process of taking off the plane

Use the air to take off from the plane

An airplane needs air to be able to fly; Birds fly by pulling and pushing air towards them, and this also happens to airplanes. Air is a substance that has weight, as Torricelli discovered in 1640 AD, and it consists of a group of gases, the largest of which are oxygen, nitrogen, and carbon dioxide, and air also contains molecules that are constantly moving, and this movement causes pressure to build up of air, resulting in the appearance of a force that lifts the plane, an upward movement, and another downward movement.^[٢]

How to lift the wings of an airplane

Airplane wings are characterized by their upward flexing, which helps to accelerate the movement of the air over the wings of the plane, while it moves in slow motion under the wing, which which means slow air moves from the bottom, and fast air from the top, and so it lifts the wing of the plane.^[٢]

Newton’s laws of motion

Isaac Newton postulated three laws of motion that help to understand how an airplane flies:^[٢]

• The object will not move on its own, and if it moves, it will not stop unless there is a reason to stop it.
• Objects move faster and farther when pushed hard.
• For every action, there is an equal and opposite reaction.

airplane power

The plane has four powers:^[٢][٣]

• upward lifting force.
• Pulling force down and back.
• Weight force down.
• Forward thrust force.

Main aircraft parts

The aircraft contains the following parts:^[٣]

• Wing system to maintain the balance of the aircraft during flight.
• Tail surfaces for aircraft balance and stability.
• Movable surfaces to control aircraft orientation during flight.
• The power plant will provide the power needed to propel the aircraft through the air.
• The wings of the aircraft to provide support during takeoff and landing.
• Most aircraft have an enclosed fuselage to accommodate cabin crew, passengers, and cargo.
• Cockpit: This is the area used by the pilot to pilot and control the flight of the aircraft.
