Question 1

Do I need an NOC to build near Darbhanga Airport?

Accepted Answer

Yes. Any structure inside the restricted radius around the airfield needs height clearance before construction, whatever its height. The requirement applies across the airport-adjacent localities, not just the closest plots.

Question 2

Who issues the NOC for a civil enclave on an Air Force base?

Accepted Answer

For Darbhanga, defence authorities issue it, not the civil airports authority alone. The airfield is IAF-owned, so height clearances run through the military channel even though AAI operates the flights.

Question 3

What is the air funnel zone and how does it limit building height?

Accepted Answer

The funnel is the runway approach corridor. Permitted height rises with distance, roughly 2 percent of the distance from the runway edge, so plots near the runway ends face a low ceiling.

Question 4

How far from Darbhanga Airport does the height restriction apply?

Accepted Answer

Limits are tightest within about 4 km, where structures cap near 45 metres. A No Objection Certificate is required within roughly 20 km of the airfield for any structure.

Question 5

Are plots near Darbhanga Airport a safe investment?

Accepted Answer

For a low home on clear title, generally yes. For tall construction, treat it as risky, since the funnel and defence NOC can block the height that the airport-proximity price assumes.

Question 6

How do I verify land ownership before buying in Darbhanga?

Accepted Answer

Check the title on Bihar's land records before paying, confirm any project carries valid RERA Bihar registration, and match the survey number to the funnel map so height is settled before purchase.
