The passengers had driven through fog-covered roads to the airport but the operations at the airport were severely affected for around five hours in the morning, as the runway visibility dropped below 50 metres.
On Saturday, Delhi recorded a minimum temperature of 7.2 degree Celsius; the maximum temperature was recorded at 22.6 degree Celsius. This is also an improvement, as RVR was in the range of 50-100 metres in the last two days. "Day temperature will fall significantly", Mahesh Palawat, Vice President at Skymet Weather, said, adding the minimum temperature of 5.7 degrees was "lowest minimum of the season". The three-hour suspension of flight operations meant that it took hours for the backlog to clear.
Departures require a visibility of at least 125 metres, while planes can land in visibility below 50 metres if the pilots are trained in CAT IIIB technology for low-visibility landings that allows qualified aircraft to land in visibility of 25-50 metres. 15 have been cancelled, the Northern Railways said.More news: Diego Costa reflects on his time at Chelsea
