Flight operations at Indira Gandhi International Airport (IGIA) were severely affected on Thursday as visibility dropped sharply due to dense fog in the morning. As many as 250 flights were delayed, six flights diverted and 16 cancelled. Besides, 16 other flights were cancelled for “other reasons”.
“Several airlines, such as IndiGo, Jet Airways and Vistara, warned of delays and diversions due to the sudden drop in visibility,” said an airport official, adding that wind speeds have reduced drastically over the last few days — with the highest wind speed recorded at 6 km per hour on Tuesday.
According to officials, 49 flights that took off from IGIA and an equal number of those that arrived were delayed as adverse conditions persisted. Around 94 flights — approximately 10 per cent of the total aircraft movement — were delayed due to “other reasons”, said officials. Airport authorities, however, could not immediately ascertain the “other reasons” which lead to the delays.
According to the Safdarjung Observatory, visibility was recorded at 50 metres at 5.30 am, which increased to 150 metres at 8.30 am. “It subsequently improved to 800 metres at 11.30 am and to 1,000 metres at 2.30 pm. The Palam weather office recorded no visibility at 8.30 am,” said an official.
The MeT Department has predicted mainly clear skies for Friday, along with the possibility of shallow to moderate fog at some places, and dense to very dense fog at isolated places.
