Overview
Nagpur airport funnel zone restrictions govern permissible building heights across a 20-km radius around Dr. Babasaheb Ambedkar International Airport. Issued under the Ministry of Civil Aviation's Height Restrictions Rules 2015, these rules are enforced by AAI through its Colour Coded Zoning Map (CCZM). Any structure above 15 meters AGL requires a height NOC via the NOCAS portal before construction. This page covers how to read the CCZM for Nagpur, which corridors face the strictest height caps, and the documents you must verify before signing any land deal near the airport.
Height Restriction Traps That Have Killed Nagpur Real Estate Projects
Funnel zones aligned with runway ends impose the harshest height limits, and they catch buyers off guard because sellers rarely disclose them. In Nagpur's MIHAN SEZ, a developer who planned 18-storey towers inside the SEZ saw AAI curtail the heights because the site sat inside the aircraft landing funnel, floors that were approved by MADC were blocked by AAI.
The CCZM for Nagpur divides the area around the airport into colour-coded grids, each carrying a Permissible Top Elevation (PTE) in metres AMSL. The table below shows how each colour grade translates into construction risk.
CCZM Colour
Meaning
Construction Route
Red Grid
Site falls inside strict restriction zone
File NOC directly with AAI via NOCAS, no local body approval
Non-Red Grid below PTE
Site elevation plus proposed height is under PTE
Local body (NMC/NIT/NMRDA) can approve without AAI referral
Any grid, structure above 150 m AMSL
Above CCZM auto-settle threshold
Must apply to AAI via NOCAS regardless of colour
Funnel Zone (runway axis)
Height = 2% of distance from runway edge
Strictest zone; a plot 1,000 m from runway end has a 20 m height cap

Non-Red Grid below PTE

The formula is simple but deadly: if a broker quotes you the Floor Space Index (FSI) without first checking the CCZM grid and subtracting site elevation from the PTE, you are being sold a number that may be legally unreachable. If your Nagpur airport height restriction NOC check reveals a red grid, the local body cannot issue a construction permit, only AAI can.
MIHAN, Jamtha, Besa and Wardha Road: Which Corridors Have Room and Which Don't
South Nagpur's growth corridors are the most active land investment zones in the city, and they all sit inside AAI's 20-km NOC radius.
The table below maps the four key corridors to their investment profile and height risk.

Jamtha is one of Nagpur's most active plot markets, but buyers regularly ignore that it sits inside the conical surface zone, where heights slope upward at 5% gradient from the airport perimeter. A layout sanctioned by NMRDA for G+3 floors can still be blocked at the construction permit stage if the CCZM PTE for that grid is lower than the proposed top elevation. Wardha Road's outer belt, beyond 10 km from the Aerodrome Reference Point, faces the most relaxed restrictions and is where NMRDA-approved layouts can typically achieve full permitted FSI without AAI referral.

Frequently Asked Questions
Any structure within 20 km of Nagpur airport requires AAI height NOC if it exceeds the CCZM Permissible Top Elevation for its grid. In the runway funnel zone, the permitted height equals 2% of the distance from the runway edge.
Download the AAI CCZM for Nagpur from nocas2.aai.aero. Locate your plot's grid, note its colour, and check the Permissible Top Elevation. Deduct your site's ground elevation (AMSL) to find the maximum permitted construction height above ground.
Buying land does not require an NOC. Construction does. Any structure above 15 m AGL within the NOC zone must obtain height clearance from AAI via the NOCAS online portal before the local body can sanction the building plan.
CCZM is AAI's Colour Coded Zoning Map showing Permissible Top Elevation (AMSL) per grid square. Red grids require direct AAI application. Non-red grids below the PTE can be cleared by NMC, NIT, or NMRDA. Always check the correct Nagpur airport height restriction CCZM before agreeing on a purchase price.
Yes, but with severe height caps. MIHAN core plots fall partly inside the landing funnel zone where AAI curtailed even MADC-sanctioned projects. Any MIHAN land deal must carry the AAI NOC as a pre-condition before construction, not an afterthought.
Verify the CCZM grid colour and PTE for the specific survey number, obtain the NMRDA or NIT layout approval, confirm the title document and encumbrance certificate, and check for any existing AAI NOC on record before signing any agreement.
