New Delhi:
Dense fog continued to hit flight operations at the IGI airport for the second consecutive day on Thursday, disrupting the schedules of around 80 domestic and international flights.
"Since last night 27 domestic and international flights were diverted, 18 were cancelled and around 20 have been rescheduled as thick fog blanketed the airport reducing the runway visibility to 150 metres or less," an airport official said.
Some of the morning flights were delayed by over two to three hours while a few operated using the CAT-III B instrument landing system.
Five flights of Air India took off using Category Instrument Landing System. These included a flight to Kabul as well as to Mumbai, Nagpur and Chennai.
Fog started to descend over the airport last night around 8 pm reducing the general visibility to around 50 metres and within half an hour the general visibility dropped to zero while runway visibility to a low of 100 metres, forcing the airport authorities to divert some domestic and international flights.
The runway visibility remained around 150 metres throughout the night due to which international flights, which were scheduled to depart on Wednesday night and early on Thursday morning, were worst hit, the official said.
