Aviacao
In short
Aviation involves the design, development, production, operation, and use of aircraft. It covers everything from small private planes to massive commercial jetliners.
In plain words
It is the science and business of flying through the air. This includes pilots, engineers, air traffic controllers, and the machines they use to travel.
A simple example
A passenger boarding a Boeing 747 for a holiday in London is part of the aviation industry. A pilot navigating a small propeller plane through clouds is also practicing aviation.
Why it matters
It allows people and goods to move across the globe much faster than by sea or land. It is vital for international trade, emergency rescues, and global tourism.
Easy to mix up
Do not confuse aviation with aerospace, which also includes travel and technology used in outer space.
