The International Civil Aviation Organization (ICAO) has commenced a nine-day audit of India's aviation security, focusing on the Bureau of Civil Aviation Security (BCAS) at Delhi and Kolkata airports. This audit, involving a dozen experts from 10 countries, will assess India’s compliance with global security standards, including regulatory frameworks and operational procedures. The ICAO's last audit in 2018 raised concerns about BCAS's autonomy, a point India has since addressed with recent legislative changes.
