Recreational aviation refers to flying airplanes for fun, rather than for business or military purposes. In Australia, there is an organization called Recreational Aviation Australia (RA-Aus) that helps people learn how to fly and enjoy recreational aviation safely.
So imagine you have a toy airplane and you love playing with it. Now, some grown-ups love flying real airplanes for fun too! They have special places where they can practice and learn how to fly safely without bothering anyone else. RA-Aus is like a group of grown-ups who help other grown-ups learn how to do this and have fun while being safe.
They also have rules and guidelines to make sure everyone is safe. These rules are like a set of instructions that everyone needs to follow. When the grown-ups who love flying follow these rules, they can have a great time flying their airplanes and enjoying the beautiful views from up high.
In summary, Recreational Aviation Australia is a group of grown-ups who help other grown-ups learn how to fly airplanes for fun safely by following some rules.
