Flight operations at New Delhi's Indira Gandhi International (IGI) Airport were disrupted for nearly two hours on Tuesday morning due to dense fog resulting low visibility. The minimum visibility required for take off is 125 metres.
Three international and one domestic flights were diverted due to poor visibility. However, arrivals were not affected, an official said.
According to the official, since the Low Visibility Take Off (LVTO) requirement is not being fulfilled, departure of flights were on hold for two hours from around 7:15 am.
Departure of flights resumed at 9:16 am.
The Indira Gandhi International Airport is the busiest in the country and on an average sees more than 70 flight movements per hour. This includes both arrivals and departures.
