Dholera Air Funnel Zones
AAI
Overview
Every plot within 20 km of the Dholera International Airport's Aerodrome Reference Point falls under an AAI-regulated airspace layer. This is the Dholera Airport height restriction zone land buying check that almost no broker explains upfront. The airport, currently under construction near Navagam village in Dholera taluka, Ahmedabad district, is being developed by Dholera International Airport Company Limited (DIACL) across a 1,426-hectare site. Under the Ministry of Civil Aviation (Height Restrictions for Safeguarding of Aircraft Operations) Rules, 2015, every structure in the zone requires a verified height clearance.

The critical trap: AAI's rules apply from the date the airport is technically cleared, not from the date operations begin. Dholera received site clearance in July 2014 and environmental ministry approval in December 2015. The CCZM obligation has therefore been active for years, covering plots that sellers routinely market as unrestricted. If a developer cannot show you a NOCAS-generated height clearance letter alongside the DSIRDA NOC, the project has not completed its full legal stack.
Frequently Asked Questions
What is the height restriction zone around Dholera airport?
Covers all land within 20 km of the ARP at Navagam. AAI's CCZM assigns each grid a permissible top elevation in AMSL minus your plot's verified site elevation.
Do I need an AAI NOC to buy or build near Dholera International Airport?
No NOC needed to purchase land. But construction requires an AAI NOC via NOCAS before DSIRDA issues building permission, regardless of your TP scheme approval status.
What is the CCZM for Dholera Airport, and how do I access it?
Published by AAI and accessible at nocas2.aai.aero. Enter your WGS-84 plot coordinates to find your zone color and permissible top elevation. Applies from the technical clearance date, not the airport opening.
How do I check if my Dholera plot falls inside the air funnel zone?
Log on to NOCAS, enter WGS-84 coordinates, and input the licensed surveyor-certified site elevation. Plots above 300 sq m need all four corners. The system returns your zone color and NOC requirement.
What documents do I need to buy a plot in Dholera SIR near the airport?
DSIRDA layer: NA order, NOC, TP approval, title deed, and 7/12 extract. Airport layer: NOCAS height clearance letter. Both stacks are independent; missing either means an incomplete legal transaction.
Can I build a house near Dholera airport in an approved TP zone?
Yes, but two approvals are mandatory: DSIRDA construction permission under GDCR and an AAI NOC confirming your height doesn't breach the CCZM permissible top elevation. Proceeding with only one is a violation.
What is NOCAS, and how do I apply for height clearance near Dholera Airport?
AAI's online NOC portal at nocas2.aai.aero. Submit WGS-84 coordinates, surveyor-certified site elevation, and building plans. Processing takes three weeks. An approved NOC is valid for eight years.
What is the difference between the Dholera SIR TP zone and the AAI airport funnel zone?
TP zones regulate land use, FAR, and setbacks under the Gujarat SIR Act. AAI funnel zones regulate absolute building height in AMSL under central aviation law. Both must be satisfied independently before construction.
