🛡️ Air Defence Clearance (ADC): Critical Guidelines for Operating Within Bangladesh ADIZ

In the interest of national security and controlled airspace management, Bangladesh has officially established an Air Defence Identification Zone (ADIZ) that spans the entirety of its territory, including land borders with India and Myanmar, and extends southward into the Bay of Bengal. This ADIZ functions as the first line of defence against unauthorised aerial incursions.

All foreign and local aircraft, whether civilian or military, must obtain an Air Defence Clearance (ADC) number before operating into, through, or within the Bangladesh ADIZ.
