Definition

Aviation is the science and practice of flying. It includes the design, construction, operation, and maintenance of aircraft. Aviation also includes the study of the atmosphere and the forces that affect flight.

Aviation has a long and rich history. The first recorded flight was made by the Wright brothers in 1903. Since then, aviation has become an essential part of modern life. It is used for transportation, communication, and recreation.

There are many different types of aircraft, including aeroplanes, helicopters, and gliders. Aircraft are powered by a variety of sources, including propellers, jets, and rockets.

Aviation is a complex and challenging field. It requires a deep understanding of physics, engineering, and meteorology. However, it is also a very rewarding field. Aviation has the potential to change the world, and it offers many opportunities for innovation and discovery.

How can the word be used?

Etymology

The word "aviation" comes from the French word "aviation", which was coined in 1863 by the French engineer and aviation pioneer, Jean-Marie Le Bris. The French word "aviation" is derived from the Latin word "avis", which means "bird", and the verb "avitare", which means "to fly like a bird".

AQA Science Exam Question and Answer

Question:

Define "aviation" and explain the underlying principles that enable flight in aviation. Discuss one significant advancement in aviation technology that has revolutionized air travel.

Answer:

  • Aviation is the field of science and technology related to the design, development, and operation of aircraft, including aeroplanes and helicopters. The underlying principle enabling flight in aviation is Bernoulli's principle, which states that as the speed of air increases, its pressure decreases. This principle allows aircraft wings to generate lift, allowing planes to rise and stay aloft in the air.
  • One significant advancement in aviation technology is the development of jet engines. Jet engines, first used in commercial aviation in the 1950s, replaced propeller-driven engines and brought about a dramatic improvement in speed, efficiency, and range for aeroplanes. The introduction of jet engines revolutionised air travel, making it faster, more reliable, and accessible to a larger number of people worldwide.
