Flight operations at the IGI airport here was partially affected today after dense fog enveloped the city.
Five flights, two domestic and three internationals, were diverted, eight cancelled and over 100 arriving and departing were delayed by over 15 minutes, airport officials said.
Fog started to envelope the airport around midnight last night and become dense between 12.30 AM and 3.30 AM. The visibility on all the runways dropped.
The visibility at the third runway was below 50 metres, due to which it became inoperational during this period, they said. The visibility at the main runway dropped to 125 metres, but it was operational, they added.
"Most of the diversions were due to pilots not being trained to land in low visibility conditions," airport sources said.
