Flight operations at Delhi airport were affected today as dense fog brought down visibility in some parts of the national capital to zero. Passengers have been advised to contact their respective airlines for updates on their flights.

“While landings and take-offs continue at Delhi Airport, flights that are not CAT III compliant may get affected. Passengers are requested to contact the airline concerned for updated flight information. Any inconvenience caused is deeply regretted,” reads the advisory issued by Delhi Airport.

The airport authorities initiated the anti-fog landing system, technically called the CAT-lll Instrument Landing System (ILS). The CAT III system helps with a precision approach and landing when the runway visibility level is low.

The mercury dipped to 9.4 degrees Celsius, as reported by the India Meteorological Department (IMD) in Delhi. The visibility in various parts of the capital plummeted to a mere 125 meters, causing widespread disruptions to daily life. The National Capital Region (NCR) also bore the brunt of the thick fog, resulting in low visibility across most areas.
