After some respite, a fresh spell of fog delayed many flights on Friday. Fog might return on Saturday to trouble air passengers.

Around 2.31 a.m., Delhi’s Indira Gandhi International Airport was enveloped by a blanket of fog, which thickened by 7.26 a.m. While flights were delayed in the morning, the situation worsened in the evening when many more flights were delayed by a longer duration.

Low visibility procedures were implemented in the morning after the runway visual range went below 1,200 metres and lifted at 9.50 a.m. after visibility improved. The dense fog period remained for almost two and a half hours. A total of 51 flights (45 domestic and 6 international flights) operated in this period.

While there were no major flight delays in the morning, almost all domestic departure and arrival flights were delayed by half an hour to one hour in the afternoon and early evening. Visibility again started dropping at the airport from 2.07 p.m. and improved after 6 p.m.

“The visibility was not too bad and both the runways were operational. Still, we witnessed air traffic congestion,” said a senior airport official. “Though there were no delays in landings or take-offs, aircraft movement on ground had slowed down because of the safeguard procedures implemented after poor visibility,” he reasoned.

“The fresh spell of fog is due to local features like falling of night temperature and calm wind conditions,” said R.K. Jenamani, director-in-charge, IGI Met unit. “Dense fog was seen for a small period between 2.30 a.m. and 3.30 a.m.,” he said.

“The fog condition might intensify on Friday,” he said.
