Question 1

Do I need an AAI NOC before building on a plot near Tirupati airport, even if the plot is TUDA-approved?

Accepted Answer

Yes. TUDA approval covers land use zoning under Master Plan 2040. AAI NOC under G.S.R. 751(E) governs building height. Both are mandatory; neither substitutes for the other.

Question 2

What is the maximum height allowed in the airport funnel zone near Tirupati Airport?

Accepted Answer

Height equals 2% of horizontal distance from the runway edge. A plot 1,000 m away is capped at 20 m. Closer plots may be restricted to one story.

Question 3

What is the CCZM, and does Tirupati Airport have one?

Accepted Answer

AAI's color-coded zoning map showing pre-calculated permissible heights. Tirupati's CCZM is downloadable from nocas2.aai.aero. Below the CCZM limit, local bodies can approve; above it, full AAI NOC is required.

Question 4

How far from Tirupati Airport do height restrictions apply?

Accepted Answer

Tirupati is an IFR airport with an ILS. The mandatory NOC radius for IFR airports is 56 km from the Aerodrome Reference Point, not the commonly cited 20 km.

Question 5

What happens if a building violates Tirupati Airport's height restrictions?

Accepted Answer

Demolition orders can be issued under the 1994 Aircraft Rules. Occupancy certificates can be refused, bank loans withdrawn, and no regularisation route exists. Aviation safety violations carry zero exemption.

Question 6

How do I apply for an AAI height NOC for a plot near the Tirupati airport?

Accepted Answer

Apply on NOCAS at aai.aero. Submit WGS84 coordinates, licensed surveyor-certified site elevation, site photographs, and Google Earth plot identification. Processing takes up to three weeks after document verification.

Question 7

Can a broker claim a plot near Renigunta is "free from airport restrictions"?

Accepted Answer

No broker has that authority. Only an AAI NOCAS clearance or CCZM-verified permitted top elevation confirms compliance. Without a NOCAS reference number for the survey number, treat any claim as unverified.

Question 8

Does the Tirupati runway expansion in February 2025 change the height restriction zones?

Accepted Answer

Yes. The runway extended from 2,286 m to 3,810 m in February 2025. The funnel zone shifted. Any pre-2025 height clearance for plots near runway ends must be re-verified on NOCAS.
