The Hush Post: The national capital got the taste of the worst fog of the season as it reduced visibility to 50 metres at the Indira Gandhi International Airport on New Year’s Eve. Travellers had a difficult time as around 350 flights were delayed, diverted or cancelled. No flights could take off from Delhi for nearly four hours between 7.30 am and 11.05 am. Weathermen predict the skies to be clear during the day with shallow fog in the mornings. RK Jenamani, director of IMD (Delhi area) and IGI airport, said, “This is so far the worst fog we have experienced this year.” Takeoffs from the IGI Airport require a minimum visibility of 125 metres. Although, the Delhi airport has advanced technology for low-visibility landings, only the aircraft qualified to land in visibility of 25-50 m could make a landing. There were around 50 diversions to nearby airports as many pilots deployed by airlines were not CAT IIIB compliant.
While visibility improved later and operations were restored to normal, there were consequential delays throughout the day and a waiting time of up to six hours was being considered normal.
