Dense fog at Indira Gandhi International Airport (IGI) in India has affected the movement of nearly 200 flights, leaving hundreds of passengers stranded yesterday.
IGI had to delay the departure of 60 morning flights and divert 18 incoming flights to airports in Ahmedabad, Jaipur, Amritsar, Chandigarh and Lucknow, as runway visibility dropped to 50m.
Flight operations came to a halt between 7am and 10am local time as the runway visibility was below the required minimum range of 125m for low visibility take-offs.
During the period, a total of 120 flights landed using CAT (category) III B instrument landing system (ILS).
The CAT III B ILS enables the aircraft equipped with necessary instruments to rely only on them and land even in blinding fog, according to hindustantimes.com.
