Fog returned to haunt the Indira Gandhi International Airport after five days on Thursday and flight operations were hit badly.
More than 50 flights were cancelled and 35 were diverted — some of them international — due to heavy fog in Delhi.
According to airport officials, flights were delayed by up to four hours as thick fog made landing and taking off
Though there was shallow fog during the day on Wednesday, the visibility was manageable and flights were operating normally.
Visibility started dropping in the evening forcing the airport authorities to implement low visibility procedure (LVP) at 8.36 in the evening.
The procedure was lifted after almost 16 hours on Thursday at 11.35 am.
“Thick fog started descending on the airport at around 11 pm last night reducing the general visibility to zero and runway visibility to less than 100 metres. While 35 flights operated using the CAT IIIB instrument landing system and another 67 using the CAT IIIA system, some flights were affected and had to be cancelled or diverted,” a senior airport official said.
The delay caused lot of inconvenience to the passengers who were to take their flights after midnight.
“There was lot of chaos at the departure terminal. Information of flights being rescheduled or being cancelled was not
easily available,” said Chittaranjan Basu, who had to take an early morning flight to Kolkata.
The passengers landing at the airport were also hassled.
“There was chaos on road outside the departure terminal. Thick fog made it difficult for private cars and taxis to move. The entire stretch of the road from the international airport to the national highway was chaotic,” said Vaibhav Arora, who came from Kuala Lumpur.
