Is Prayagraj Airport a military base or a civil airport?

Both. It's IAF-owned and hosts Central Air Command headquarters, while AAI operates the civil terminal for scheduled commercial flights under the IATA code IXD.

How far does the height restriction extend from Bamrauli airport?

The AAI civil clearance zone follows the airport's colour-coded zoning map, while the separate defence rule bars construction within 100 meters and restricts taller buildings out to 500 meters.

Do I need an NOC to build near Prayagraj Airport?

Yes, and likely two: an AAI NOC for height clearance under the Aircraft Act, plus a defence NOC from local military authority under the Works of Defence Act.

What is Central Air Command and why does it matter for land near Bamrauli?

It's the IAF command headquartered at Bamrauli, which means the base carries full military installation status alongside its civil airport role, triggering defence-specific construction rules.

Is land near Prayagraj Airport safe to buy for construction?

Yes, outside the restricted bands, provided both the AAI height clearance and the defence distance rule are checked separately before any building plan.

Which distance rule applies, 20 km or 56 km, for Prayagraj Airport?

That depends on the airport's instrument rating and CCZM classification; check the specific permissible top elevation for your coordinates directly on AAI's NOCAS portal.

Does the Kumbh Mela expansion affect height restrictions near Bamrauli?

No. Terminal expansion for Kumbh 2025 raised passenger capacity but didn't change the underlying AAI or defence height restriction rules around the Bamrauli air funnel zone Prayagraj.

What happens if construction near Bamrauli lacks a defence NOC?

It risks legal action from the military authority controlling the base, independent of any AAI clearance already obtained for the same structure.

IAF Air Funnel Zones - Prayagraj

Overview

The Bamrauli air funnel zone Prayagraj sits on a dual-use footprint few buyers fully register: Prayagraj Airport (IXD) is a joint civil-military installation, owned by the Indian Air Force and operated for scheduled flights by AAI, and it also serves as headquarters for Central Air Command. It's one of India's oldest aerodromes, dating to 1931, sitting in the Bamrauli suburb about 12 km from the city center. Because it holds both an active civil terminal and a functioning IAF base, land nearby answers to two overlapping legal systems at once. This page covers both and where the recent Kumbh-driven expansion changes the picture.

Regulatory Red Flags Near Bamrauli

Because Prayagraj Airport runs scheduled commercial flights under an IATA code, standard AAI height clearance rules apply the same way they would at any civil airport: no structure can go up without a No Objection Certificate from AAI's NOCAS system, with the permissible top elevation set by the airport's colour-coded zoning map. But because the same site is also an active IAF base and Central Air Command headquarters, the Works of Defence Act, 1903 layers on top of that. Current Ministry of Defence guidance under this Act bars construction outright within 100 meters of the defence installation, and requires a separate NOC from local military authority for any building over four floors out to 500 meters.

Buyers near Bamrauli often clear the civil NOC and assume they're done. They aren't. The defence-side clearance is a separate approval, issued by a different authority, and skipping it has triggered real litigation elsewhere in India when construction proceeded on AAI clearance alone.

The table below lays out both approval tracks.

Confirm both clearances before treating a plot near the airport as buildable, and don't accept a broker's word that "the airport NOC covers it."

Growth Areas Around Prayagraj Airport

Prayagraj Airport just went through its biggest capacity jump in decades. A new terminal completed in January 2025 ahead of Kumbh 2025 pushed the airport past one million annual passengers for the first time, on top of the 2018 civil terminal extension built for Kumbh 2019. That kind of sustained infrastructure investment tends to pull residential and commercial interest toward the surrounding corridor, but it doesn't loosen the height restriction bands in any way.

The table below shows where that growth pressure sits against the restriction zones.
