Delhi International Airport Ltd (DIAL) officials said standard procedures linked to low visibility were put into force early Friday morning as the visibility dropped. Passengers were asked to check with airlines for information regarding flight operations.

“Airlines that complied with the CAT III landing and takeoff protocol were not impacted,” an official said. CAT III protocol is put in place as visibility dips so that flights can operate in low-visibility conditions. Pilots have to be specifically trained for it.

Where else have flights been impacted?

Besides Delhi, Srinagar, Chandigarh, Agra, Lucknow, Amritsar, Hindon and Gwalior airports also reported zero visibility.

A thick layer of fog engulfed Kashmir in the morning. Poor visibility due to the fog affected operations at the airport and all morning flights were delayed, officials said.

They added: “Due poor visibility at Srinagar airport, no flight operations have taken place so far. All airlines have rescheduled their morning operations till the visibility improves.” This is the second consecutive day that fog has affected flights at Srinagar airport.
