Dense fog once again disrupted flight schedules at Indira Gandhi International (IGI) Airport on Monday. And according to the met department, fog is going to stay for some time.
At least 50 flights were delayed, six cancelled, 19 rescheduled and one had to be diverted to Jaipur after dense fog descended at the airport at 12.50 a.m. on Monday. The dense fog period remained for more than nine hours and low visibility procedures were lifted at 10.05 a.m.
A total of 113 flights operated during this period, including nine flight movements in CAT III-B conditions. Both the runways were operational for most of the time on Monday morning.
An Air India flight from Muscat to Delhi was diverted to Jaipur around 3.15 a.m. when the general visibility was zero and the runway visibility range (RVR) was 100 metres.
“The fog is not going to improve much in the coming days because fresh western disturbances are approaching and fog situation would remain the same,” said R.K. Jenamani, Director-in-charge of the IGI met unit.
“There are no signals of the fog weakening with humidity levels still as high as 80 per cent and IGIA would witness dense fog till at least January 31,” he said. Situation on Tuesday, however, could be slightly better thanks to better wind speed, which helps in blowing away the fog.
“Dense fog would set in late on Tuesday but would remain in the early morning, though the intensity might be lesser,” he said.
On Monday, the airport witnessed the worst fog period between 1.30 a.m. and 9 a.m. at the new runway and between 2.30 a.m. and 5.30 a.m. at the main runway. The lowest the runway visual range touched was 75 metres. “Thanks to strong wind, visibility became better later in the day,” he said.
