IAF Air Funnel Zones - Gorakhpur

Start with the fact most brokers skip. Gorakhpur's airfield is an Air Force base. AAI merely runs the passenger terminal on it. That single distinction changes your paperwork and your permitted height.

Below is how the height restrictions near military airfield surfaces translate into real limits around the base.

The runway here runs close to 9,000 feet on the 11/29 alignment, so the funnel stretches well past the terminal along that axis. Anything you build inside the restricted radius needs a No Objection Certificate first. Because this is a defence-owned field, defence authorities issue NOC decisions, not the civil airports side alone, and the base is currently being upgraded for MQ-9B drone operations, which keeps scrutiny high. The surface maths follows standard NOC obstacle limitation surfaces rules, but the file runs through the military desk. When a project promises you a tower "minutes from the airport," it is describing the tightest part of the funnel. Pull the survey number and check it against the line before any money moves.

Gorakhpur is booming for real reasons: the Purvanchal Expressway, AIIMS, GIDA industrial zones, and the revived fertilizer plant. That growth is genuine. Whether a given plot can carry height is a separate question, and it depends on where it falls against the runway.

This table lines up the active corridors with their likely funnel exposure.

The corridor buyers read most optimistically is the airport-and-AIIMS cluster, where listings openly advertise "airport 2 km, AIIMS 3 km" as pure upside. For a home, that proximity is fine and often worth paying for. The catch is vertical. These plots fall within the inner horizontal surface, so a house clears while an apartment block runs into the defence NOC. Around Kunraghat and Gorakhnath, where colonies press against the sprawling Air Force area near Kushmi, the funnel is tighter still. Buy to live, and you are usually clear. Buy betting on a high rental tower beside the runway, and the Air Force, not the market, decides your top floor.
