What are the IAF Air Funnel Zones for Lucknow and Bakshi Ka Talab?

They are height-restricted corridors under GSR 751(E), aligned with the runway approach and departure paths of Chaudhary Charan Singh International Airport and Bakshi Ka Talab Air Force Station, designed to keep structures from obstructing aircraft operations.

How far apart are CCSIA and Bakshi Ka Talab Air Force Station?

The two aerodromes sit approximately 25 km apart. Since each carries a mandatory 20 km NOC radius, their zones overlap across a meaningful band of territory between central Lucknow and the Bakshi Ka Talab area.

Has Lucknow ever enforced height restriction violations near its airport?

Yes. The Lucknow Development Authority, district administration, and municipal corporation jointly ordered the additional floors of 21 buildings exceeding the funnel area's 9 metre threshold near CCSIA to be demolished.

Is Bakshi Ka Talab Air Force Station open to civilian flights?

No. It is a defence-only base under Central Air Command with no civil enclave, unlike CCSIA. Any construction near it needs clearance through Indian Air Force channels rather than AAI's civilian NOCAS process.

What is the exact height formula used near the runway approach path?

Permitted height equals 2 percent of the distance from the runway edge, a 1:50 slope. A structure 1,000 metres from the edge along the approach path is capped at roughly 20 metres.

Can a plot fall inside funnel zones for both CCSIA and Bakshi Ka Talab at once?

Yes, particularly along the corridor between central Lucknow and Bakshi Ka Talab. Such a plot needs its Permissible Top Elevation checked against both aerodromes' zoning data before construction.

Does the Lucknow Development Authority handle airport height clearance too?

The LDA handles standard local building plan approval, but height clearance itself comes from AAI for CCSIA-related plots or the Indian Air Force for Bakshi Ka Talab-related plots, as a separate requirement.

What happens if a building is constructed without a height NOC in Lucknow?

Lucknow has direct precedent here. Authorities have already ordered demolition of additional floors on buildings that exceeded the funnel area's height threshold near CCSIA without the required clearance.

Zone

IAF Air Funnel Zones - Lucknow

Overview

The Lucknow Bakshi Ka Talab Air Funnel Zone covers the construction height restrictions radiating from two active aerodromes: Chaudhary Charan Singh International Airport at Amausi, a public airport operated by an AAI-Adani Group consortium, and Bakshi Ka Talab Air Force Station, a defence-only Indian Air Force base under Central Air Command roughly 25 km away. Every structure within 20 km of either Aerodrome Reference Point needs a No Objection Certificate under the Ministry of Civil Aviation's GSR 751(E) rules, and Lucknow has already enforced this against real buildings. This page maps which surface zone applies to which locality, what height each one actually permits, and where the two aerodromes' zones can overlap.

Regulatory Red Flags Around the Lucknow Bakshi Ka Talab Air Funnel Zone

Lucknow is not a city where height violations stay theoretical. District authorities, the Lucknow Development Authority, and the Lucknow Municipal Corporation jointly agreed to act against 21 buildings found violating the Airport Act near Chaudhary Charan Singh International Airport, ordering the additional floors of buildings that exceeded 9 metres in the funnel area, some reaching 12 metres, to be demolished. That enforcement history is worth knowing before anyone tells you a height violation here is unlikely to be caught.

Lucknow's dual-aerodrome geography is the detail most brokers skip. CCSIA at Amausi and Bakshi Ka Talab Air Force Station sit only about 25 km apart, and since each aerodrome's mandatory NOC radius extends 20 km, the two zones overlap across a meaningful stretch of territory between them. A plot in that overlap band can fall under both a civilian AAI process tied to CCSIA and a defence-administered process tied to Bakshi Ka Talab at the same time, and clearing one does not automatically clear the other.

Bakshi Ka Talab itself deserves separate attention because, unlike CCSIA, it has no civil enclave and no AAI passenger operations. It is a Central Air Command base hosting No. 35 Squadron, an electronic warfare and air superiority unit, and any construction proposal near it runs entirely through Indian Air Force channels rather than the more familiar civilian NOCAS portal.

Confirm both the applicable Permissible Top Elevation and which aerodrome's clearance process governs a specific survey number with the Lucknow Development Authority and the relevant Air Force or AAI office before signing an agreement.

Growth Corridors and Micro Markets Around the Lucknow Bakshi Ka Talab Air Funnel Zone

Distance from each aerodrome, and position relative to each runway's flight path, together decide what a plot can actually carry. Amausi and the Bakshi Ka Talab corridor behave very differently from each other.

Corridor / Locality

Zone Status

Growth Driver

Known Risk

Amausi, immediate CCSIA vicinity

Inner Horizontal Surface and Funnel overlap

Direct airport-adjacent land, 6.44 million annual passengers, NH-27 and Lucknow Metro Red Line connectivity

The 45 metre inner surface cap already led to real demolition orders here; confirm compliance before assuming height flexibility

Sitapur Road and Jankipuram corridor toward Bakshi Ka Talab

Outer Horizontal Surface, may straddle both aerodromes' zones

Emerging residential corridor connecting central Lucknow to the BKT area

Confirm which aerodrome's funnel actually governs a given plot, since the two bases sit only about 25 km apart

Bakshi Ka Talab town, immediate AFS vicinity

Inner Horizontal Surface and Funnel, defence-only base

Small nagar panchayat town with limited commercial airport pressure

No civil enclave exists here, so clearance runs through Air Force channels rather than a civilian-facing process

Central Lucknow city core, roughly 10 to 15 km from CCSIA

Outer Horizontal Surface

Established urban demand alongside NH-27 and Metro Red Line growth

Still requires an AAI NOC for taller structures; distance alone does not exempt a plot

CCSIA's own growth trajectory, now the 11th-busiest airport in India by passenger traffic and serving as an IndiGo focus city, keeps commercial pressure high around Amausi, which is precisely why height violations kept appearing there in the first place.

The corridor running from central Lucknow out toward Bakshi Ka Talab along Sitapur Road deserves the closest scrutiny of all, since it is the one stretch where a buyer genuinely cannot assume which aerodrome's rules apply without checking both. A plot that looks safely outside CCSIA's funnel on a simple radius map can still sit inside Bakshi Ka Talab's, and the reverse is equally possible.
