The general visibility at Indira Gandhi International Airport in Delhi on Monday was reduced to barely 50 metres, with the temperature hovering around 11 degrees Celsius. This prompted the airport to activate CAT-3 measures. This is a specialized navigation system used when visibility is very low, allowing equipped aircraft and trained pilots to land in thick fog. While CAT III allows for landings, the low visibility often causes a backlog. Passengers should expect delays and potential cancellations, the airport said in a statement.

“Do not head to the airport without confirming your flight status first. Contact your airline directly via their app, website, or customer service helpline,” Delhi IGI airport advised.
