Dense Fog Disrupts Delhi‑NCR Air Traffic as IGI Airport Switches to CAT III Operations

Dense fog conditions across Delhi‑NCR have significantly disrupted air traffic, leading airlines to warn passengers of potential delays and schedule changes as visibility levels dropped sharply in the region.

In response to the reduced visibility, Indira Gandhi International (IGI) Airport implemented CAT III instrument landing system (ILS) procedures, allowing aircraft equipped with compatible systems and trained crews to operate safely in low‑visibility conditions. CAT III operations are a critical measure during North India’s winter fog season to maintain airport functionality.

Despite the advanced landing procedures, several flights experienced delays as airlines adjusted operations to ensure safety. Passengers were advised to check flight statuses before heading to the airport, as ground operations and departure sequences were also impacted by the weather conditions.

Dense fog is a recurring winter challenge for aviation in northern India, often affecting not only Delhi but also connecting flights across the domestic network. Airlines and airport authorities typically activate contingency plans during such periods to minimise disruption while prioritising operational safety.

Aviation authorities continue to monitor weather conditions closely, with further delays possible if visibility remains poor in the coming hours.
