New Delhi: A thick cover of fog enveloped Delhi’s skyline on Sunday morning resulting in enhanced chill and decline in visibility and in turn affecting flight operations.
The temperature plummeted with minimum recorded at 7 degrees Celsius early morning, and the visibility reduced to about 100 metres according to the weather department.
The dense fog halted flights for an hour and 20 flights were delayed while two were cancelled as the fog enveloped the IGI airport suddenly around 7 am, sources said.
The runway visibility being far less than the required minimum limit of 125 metres (for smaller aircraft) and 150 metres (for bigger aircraft), no flights were taking off, an airline official said, forcing the airlines to hold back the departure of flights.
Situation started to improve after 8.30 am when visibility rose to 300 metres.
As the day wears on, the fog is expected to diffuse away and visibility too is assumed to improve.
According to the Met Department, the sky will be clear and visibility would increase to 600 metres in the shallow fog of the afternoon.
