Question 1

Do I need an AAI NOC to build near Chennai airport?

Accepted Answer

Yes. Every structure within 20 km of Chennai International Airport's Aerodrome Reference Point requires an AAI height clearance NOC under GSR 751E before construction begins. There are no exemptions based on plot size or building type.

Question 2

What is the maximum building height allowed within 3 km of Chennai airport?

Accepted Answer

Within the inner horizontal surface (up to 4 km from the ARP), the ceiling is 45 m AGL. Inside the airport funnel zone, the limit equals 2% of your plot's distance from the runway edge. Your AGL headroom depends on your AMSL site elevation.

Question 3

Does Chennai airport have an official CCZM from AAI?

Accepted Answer

Yes. AAI has published a Colour Coded Zoning Map for Chennai (Drawing No. AAI/14-A, Version 1.0, 2015), available on the NOCAS portal. The Chennai airport ARP elevation is 10.363 m AMSL, and all PTE figures in the map are AMSL values.

Question 4

How is permitted building height calculated for a Chennai plot near the airport?

Accepted Answer

AAI uses AMSL. Subtract your plot's ground elevation from the CCZM Permissible Top Elevation to get the AGL ceiling. Chennai's low-lying terrain means this calculation often produces a tighter AGL figure than buyers expect.

Question 5

What happens if a building near Chennai airport violates the AAI height restriction?

Accepted Answer

Violation of GSR 751E can result in denial of Occupancy Certificate, AAI show-cause notices, and in serious cases, court-ordered demolition of non-compliant floors. The buyer inherits the legal liability after registry.

Question 6

What is the airport funnel zone and why does it affect Pallavaram and Chromepet plots?

Accepted Answer

The funnel zone runs along both runway approach and departure paths. Pallavaram and Chromepet sit directly along the runway 07/25 approach corridor, so their funnel zone ceiling is strictly distance-dependent: 2% of distance from the runway edge, calculated in metres AGL.

Question 7

Will the Parandur greenfield airport create new height restriction zones near Kanchipuram?

Accepted Answer

Yes. Once notified as an operational civil aerodrome, Parandur airport will trigger a fresh 20 km NOC radius under GSR 751E. Plots in Parandur, Ekanapuram, and Sriperumbudur will fall within its OLS surfaces. Check zone status before buying in that belt.

Question 8

How do I apply for the AAI height clearance NOC for a Chennai plot?

Accepted Answer

Apply through NOCAS at nocas2.aai.aero. Submit your plot's WGS84 coordinates and surveyed site elevation in AMSL. AAI's Chennai NOC office processes applications; the NOC is valid for eight years once issued.
