Urban Encroachment Puts Pressure on Airfield Safety
Patna’s airport is boxed in. Not metaphorically — physically. As of September 2025, the urban expansion around the airstrip has pushed right up to its perimeter, leaving almost no breathing space for safe flight operations. On all sides, concrete and crowding are closing in.
Surrounded on All Sides
The airport sits in a densely built-up area with minimal runway extension possibilities. To the south is the bustling Ashok Rajpath. To the north: residential neighborhoods and a railway line. East and west? Packed housing, schools, commercial properties. Expansion or emergency diversions are logistically constrained.
For modern aviation standards, this proximity is a problem. Runway End Safety Areas (RESAs) are barely compliant. Most global benchmarks suggest a minimum RESA of 240 meters; Patna manages just about 90 meters in key directions. With no flat land to build outwards, the risk multiplies for takeoffs and landings under sub-optimal conditions.
Topographical Headaches Amplify Risk
Adding to the problem: the Ganges River. The wide, meandering water body lies just 2.5 km north of the airport, creating low-lying fog traps during winter and strong crosswinds during summer monsoons. This is not a side note — it’s a major issue. Fog events in January 2024 alone forced over 30 diversions and cancellations.
Visibility drops fast. Flight crews often contend with shifting wind shear caused by thermal differences between the river basin and the tarmac. Even the most experienced pilots can find approaches tricky, particularly during the November to February season, when fog persists past mid-morning hours.
Bird Activity from Nearby Wetlands
Wildlife strikes are another threat. The proximity of wetlands and open garbage dumps makes the airport an unintended hotspot for bird activity. According to local aviation authority reports from June 2024, there were 17 bird strike incidents in the prior twelve months. That’s significantly above the acceptable global average.
These events are more than inconvenient; they’re dangerous. Jet engines ingesting birds mid-air often lead to emergency landings and costly aircraft inspections. Ground staff have limited mitigation tools beyond periodic scaring and loudspeaker deterrents.

Proposals and Partial Fixes
Authorities are not sitting idle. In 2024, plans were submitted to extend the runway by 300 meters. But land acquisition is stalled by a cocktail of legal disputes and local opposition. Even if green-lit, construction would take years and may only marginally improve the operating margin for larger jets.
There’s also a proposal to shift commercial operations to Bihta, where the Indian Air Force already runs a functional runway. While technically feasible, the challenge lies in logistics: distance from the city center, lack of public transit, and no current passenger infrastructure. Meanwhile, the existing airport remains the city’s only civil aviation gateway.
Technology-Based Safety Buffers
New Instrument Landing Systems (ILS) were installed in December 2023, improving landing precision during low visibility. However, these are band-aids, not root solutions. Pilots still need sharp reflexes and contingency readiness when facing poor weather, bird flocks, or runway overrun scenarios.
Growth Meets Gridlock
Patna is one of the fastest-growing Tier-II cities in India, with increasing air traffic demand. In FY 2024–2025, total passenger footfall exceeded 3.5 million, a 14% jump from the prior year. But the airport’s core infrastructure — built in another era — is bursting at the seams. Crowded apron space, limited taxiway maneuverability, and a single runway mean delays compound quickly.
The need for a parallel facility or significant upgrades is not optional anymore — it’s essential. Each day of delay tightens the operational noose, while urban sprawl adds layers of complexity to any potential resolution.
Stakeholder Stalemate
Any safety overhaul requires coordination between civil aviation bodies, local government, defense stakeholders, and private developers. So far, that hasn’t happened at the pace needed. Meetings have taken place — resolutions haven’t. In June 2025, a multi-agency roundtable ended without concrete progress. Everyone agrees on the problem; no one agrees on the path forward.
The cost of inaction will not just be measured in statistics — it may come at the expense of safety. And for a city of Patna’s scale and ambition, that’s a risk it can’t afford to ignore.
