NOC from AAI for Height Clearance Approval

When planning the construction of high-rise buildings, towers, chimneys, or any tall structures near airports, obtaining the No Objection Certificate (NOC) from the Airports Authority of India (AAI) for Height Clearance is a mandatory regulatory requirement. This ensures that the proposed structure does not interfere with aircraft operations and adheres to aviation safety norms.

This NOC is essential for:

• Residential and commercial high-rise buildings

• Telecommunication towers and transmission lines

• Industrial chimneys and windmills

• Construction cranes or hoardings

• Any structure exceeding height thresholds near airports or air routes

When Is It Required?

An AAI NOC is required when a structure is:

• Located within a 20 km radius of a civil or defense airport

• Positioned along aircraft landing/takeoff routes
