New Delhi: Operations at IGI airport here were once again affected today due to dense fog which hit the schedules of over 100 flights causing inconvenience to the passengers.
After a day of respite, fog returned at the airport this morning and reduced the visibility to below 50 metres at one end of the third runway, virtually shutting the operations on this runway.
This brought take-offs from the third runway to a halt but landings were taking place using CAT-III B instrument landing system.
A total of 11 flights landed using CAT-III B, nine with CAT-III A, 10 CAT-II and 30 using CAT-I ILS. The runway visibility kept fluctuating between 125 to 175 metres during the early hours, due to which take-offs were delayed as airport authorities faced problem in maintaining the schedule of the flights.
Three flights—one freighter aircraft, a Jet Airways flight from Abu Dhabi and a Turkish Airlines flight from Istanbul—had to be diverted as the pilots were not trained to land aircraft when the visibility is less than 200 metres, airport sources said.
