Introduction
Before beginning any construction near an airport, it’s important to ensure your project follows the guidelines set by the Airport Authority of India (AAI). Any structure — residential, commercial, or industrial Buildings that falls within a 20 km radius of an airport must obtain an AAI Height Clearance NOC (No Objection Certificate).
This certificate ensures that your proposed building does not interfere with aircraft flight paths or air navigation safety. To make the approval process smooth, you must prepare a few essential details and documents before applying online.
Here’s a simple checklist that every applicant should go through before submitting the AAI NOC form.
Type of Structure
The first step is to define your Type of Structure clearly.
AAI requires this information to determine what kind of construction is being proposed and how it might impact aviation operations.
Common structure types include:
- Residential Building
- Commercial or Office Building
- Industrial Building
- Communication Tower or Mast
- Chimney or Windmill
You’ll also need to mention the purpose or usage of your structure with height.
Providing accurate details ensures the height clearance evaluation is done correctly
Site Details needed for AAI height clearance NOC
Accurate site details are the foundation of your AAI NOC application. They help identify your property location precisely and link it with the nearby airport’s safety zone.
Make sure to include:
- Site Description: Provide your project name, plot number, and a short description of the site (up to 500 characters).
- Size of Plot: Enter the total plot area in square meters.
- Location Details: Select your state, city, and local area (village, taluk, or town) exactly as per official records.
This information allows AAI to verify your site’s position and analyze whether the proposed height complies with local aviation limits.
Site Coordinates and Elevation for AAI height clearance NOC
AAI depends on accurate geographical coordinates to analyse whether your building will interfere with any flight paths. You’ll need to provide:
- Latitude (N) and Longitude (E) in (degrees, minutes, seconds).
- Site Elevation (AMSL): The ground level height of your site in meters above Mean Sea Level.
- Building Height (AGL): The proposed structure height in meters above Ground Level.
You can use Google Earth Pro or a licensed land surveyor’s report to obtain accurate coordinates. Always double-check your coordinates before submission — even small errors can lead to rejection or re-verification requests.
Key documents you must upload:
Having the correct supporting documents ready before applying is crucial. Missing or incorrect files are one of the main reasons applications are delayed or rejected.
1. Site Elevation Document
A certified site elevation certificate from a licensed surveyor showing the exact elevation of your land above Mean Sea Level (AMSL).
This document helps AAI calculate the total permissible height for your structure.
2. Authorization Letter
If you’re not the property owner (for example, a builder, developer, or consultant), you’ll need an authorization letter from the owner giving you permission to apply on their behalf.
Include:
- Owner’s name and property details
- Applicant’s name and contact details
- Signature, date, and owner’s ID proof
Why This Checklist Matter
Following this Airport NOC checklist ensures that your AAI application is complete, accurate, and ready for approval. A single missing detail or mismatched coordinate can cause unnecessary delays.
By preparing all the above information and documents in advance, you can move quickly through the AAI’s online portal without interruptions.
This checklist not only saves time but also ensures your project remains compliant with both the Aircraft Act and Ministry of Civil Aviation regulations.
Whether you’re constructing a new building, tower, or industrial structure getting your AAI Height Clearance NOC early is a smart, legally required step toward smooth project execution.
Conclusion : Secure your AAI height clearance NOC Early
Securing your Airport Authority of India (AAI) NOC is an essential part of any project near an airport. By preparing your structure details, verifying your site coordinates, and keeping all necessary documents ready, you can make the entire process faster and hassle-free.
This checklist acts as your pre-application guide — ensuring every developer, builder, or property owner is fully prepared before starting the AAI online NOC application. Once all details are ready, you can apply for the NOC through the AAI online portal.
Note:
- AMSL-Above Mean Sea Level
- AGL-Above Ground Level
