Aviation authorities are government agencies responsible for regulating and overseeing civil aviation within a country. They ensure the safety, security, and efficiency of air travel by setting standards for aircraft operations, maintenance, and pilot training. These authorities also manage air traffic control and enforce compliance with international aviation regulations. In many countries, aviation authorities work closely with organizations like the International Civil Aviation Organization (ICAO) to promote global aviation safety and efficiency. They conduct inspections, issue licenses, and investigate accidents to improve aviation practices and protect passengers and crew.
