The Bureau of Civil Aviation Security (BCAS) was established in 1978 as a cell within the Directorate General of Civil Aviation to coordinate aviation security matters. It was reorganized as an independent department in 1987 following the Kanishka tragedy. BCAS is the regulatory authority for civil aviation security in India, headed by a Director General of Police. Its key responsibilities include laying down aviation security standards, monitoring implementation of security rules and regulations, and ensuring security staff are properly trained. BCAS conducts surprise checks and mock exercises to test security preparedness.
