Heavy fog disrupted flight operations at the Indira Gandhi International Airport here on Friday. With the runway visibility dropping below the required limits, an IndiGo flight was diverted while many departures were put on hold since 0415 hours, airport sources said.
All landings are taking place under CAT-III B landing system, the sources said, adding arrivals resumed about an hour ago. CAT-III B allows the aircraft to land in visibility as low as 50 meters.
Minimum visibility required for CAT III landing at Delhi Airport is 50 meters and for low visibility take-off operations (LVTO) it is 125 meters. GMR-run IGIA is the only airport in the country equipped with CAT IIIB. PTI IAS DV
