Aviation safety is a term encompassing the theory, investigation, and categorization of flight failures, and the prevention of such failures through regulation, education, and training. It can also be applied in the context of campaigns that inform the public as to the safety of air travel. While flying can be lots of fun, it's important to remember that professional and amateur aviators work in a high-risk environment. It's often possible to avoid many common accidents by following the right safety procedures; however, it can be difficult to plan for all contingencies. Because of this, pilots, crew and passenger should always have access to the right aviation safety devices.
