Aviation safety is how airplanes stay safe when they fly. It is really important to keep airplanes safe because if they crash, people can get hurt.
To help keep airplanes safe, pilots who fly the plane have to learn a lot about how to fly, and they also have to know all of the rules for flying safely, like paying attention to the weather. Also, airplanes need to be checked regularly to make sure that everything works correctly. When they are in the air, all of the people who are working in the plane (like the pilot, the co-pilot and people who help the passengers) need to communicate with each other and be very careful. If something looks wrong or they are not sure what to do, they need to ask for help.
These safety precautions and rules help to make sure that all airplanes are as safe as they can be while they fly and that they only fly when it is safe to do so.
