Flight Operations Disrupted by Smog

Meanwhile, flight operations at Delhi's Indira Gandhi International (IGI) Airport continued under CAT III conditions, airport authorities stated in a post on X, though passengers may experience delays or disruptions. CAT III is a category of Instrument Landing System (ILS) that offers lower minimums for visibility and decision height. CAT III allows for almost zero visibility landings in some cases. Advanced equipment and pilot training are required for CAT III approaches.

"Flight operations continue to be in CAT III. Both arrivals and departures are taking place, though some flights may experience delays or disruptions. Passengers are requested to contact their respective airlines for the latest flight information," DAA said.

Similarly, IndiGo, in a post on X, said fog and low visibility over cities including Delhi, Amritsar, Bhopal, Chandigarh, Guwahati, Varanasi, Ranchi, and Hindon Airport may impact flight schedules. https://x.com/IndiGo6E/status/2008312425293246786?s=20

GRAP Stage-III Revoked

The Sub-Committee on the Graded Response Action Plan (GRAP) of the Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) revoked Stage-III of GRAP on Friday evening, following a significant improvement in air quality due to favourable meteorological conditions.

The government has urged people to strictly adhere to the citizen charter under Stages II and I of the extant schedule of GRAP so that the AQI level does not slip further. (ANI)
