FAQ

Frequently Asked Questions

Get answers to common questions about Airport NOC process

Airport NOC (No Objection Certificate) is a mandatory clearance from the Airport Authority of India (AAI) required for all buildings and structures within 56 km radius of an airport. As per AAI and DGCA norms, any construction within this zone must obtain height clearance to ensure it does not interfere with flight operations, radar systems, or approach/departure paths.
Any individual, builder, developer, or organization planning to construct or modify a building within 56 km of an airport requires an Airport NOC. This includes residential complexes, commercial buildings, industrial facilities, telecom towers, transmission lines, and any structure exceeding certain height limits as defined by AAI guidelines.
Key documents include: land ownership documents, approved building plans, site location map, DGPS survey report, topographic survey with contour maps, OLS (Obstacle Limitation Surface) study, structural elevation drawings, and a formal application to the regional AAI office. Our team handles the complete documentation process.
The timeline varies depending on the complexity of the project and the specific AAI regional office. Typically, it takes 30-90 days from submission of complete documentation. Our experienced team ensures faster processing by maintaining accuracy and compliance from the start, minimizing revision requests.
DGPS (Differential Global Positioning System) Survey is a high-precision surveying method used to accurately determine the elevation and coordinates of a site. For Airport NOC, DGPS surveys provide the exact height of the proposed structure above mean sea level, which is critical for AAI to assess impact on flight paths.
The 56 km radius is the zone within which AAI has authority over construction heights. This zone was established based on radar coverage, approach paths, and safety considerations. Any construction within this zone must comply with height restrictions and obtain clearance from the nearest AAI regional office.
Yes, we operate Pan India across 25+ states. Our network of certified surveyors and consultants covers all major cities and airport regions. We have successfully completed projects near airports in Delhi, Mumbai, Bangalore, Hyderabad, Chennai, Kolkata, and many other locations.
In case of rejection, we analyze the reasons, recommend modifications to the building plan if feasible, and reapply with updated documentation. Our success rate is 98% because we conduct pre-assessments and compliance checks before submission to minimize the risk of rejection.
