"There was no dense fog last night and this morning as a result runway visibility was more than 1,000 metres, so all the flights are operating as per schedule," an airport official said.
The airport experienced some fog at around 11 pm last night during which general visibility dropped to 150 metres but it did not cause disruptions to the flight movement.
Some flights were cancelled or delayed due to operational reasons or poor visibility at the destination cities, sources said.
The IGI airport has been experiencing dense fog for the last two days, due to which runway visibility dropped to less than 50 metres leading to disruptions of about 250 flights.
Taking into account the large number of flights being disrupted, the civil aviation regulatory body, Directorate General of Civil Aviation (DGCA), has convened an emergency meeting of the airport operator DIAL and other agencies
The DGCA has directed DIAL to inform the Air Traffic Control about availability of parking bays, which in turn will inform pilots of international flights through Air Traffic Information System, an automatic broadcast system.
ATC has been asked to give priority to diverted flights, and the ATC units concerned must take permission from Delhi ATC before clearing an aircraft for departure. Also, DIAL will have to make arrangements to assess the flight delays and accordingly display in the terminal building delay and rescheduling of flights for passenger information.
