Airport height clearance in India is a No Objection Certificate (NOC) confirming that a planned building or structure will not obstruct aircraft flight paths near an airport. Depending on the site, you apply for an Aviation NOC and AAI NOC (Airport Authority of India), or an Air Force NOC, Army NOC or MOD NOC when the site lies near a defence airfield or establishment. Skytech Aviation, a Pune-based consultancy, prepares the DGPS elevation survey, files the application and follows the case through to the airport height clearance NOC.

• What it is: Airport height clearance is an NOC that limits how tall your building, tower or structure can be near an airport or airfield.

What Is Airport Height Clearance in India?

Airport height clearance in India is an official permission, issued as a No Objection Certificate (NOC), stating the maximum permitted height of a structure so it stays clear of an airport's obstacle limitation surfaces (OLS), approach paths and radar or navigation aids. Without this Aviation NOC, a building near an airport can face stop-work orders, redesign or demolition under aviation obstruction rules.
