New Delhi: Flight operations came to a standstill at the Indira Gandhi International Airport on Friday due to dense fog which reduced visibility to below 50 metres and affected the schedule of over 50 flights.
The fog descended upon the airport on Thursday night and it become so dense on Friday morning that the runway visibility dropped to below 50 metres on both the runways rendering them in operational, an airport official said.
Two Jet Airways flights, one from Abu Dhabi and other from Dammam and a Lufthansa flight from Munich were diverted between 5.30 AM and 7.30 AM.
According to sources, the pilots were trained to operate flights using CATIII B instrument landing system, which helps pilot to land a plane when runway visibility is up to 50 metres.
Though there was no cancellation of flights, the schedule of over 50 flights was disrupted as no flight could take off from 6 AM due to runway visibility dropping to less 125 metres, the required minimum parameter for an aircraft to take off in low visibility conditions.
The visibility at the third runway (29/11) started to deteriorate from 1 AM, forcing the airport authorities to implement low visibility procedures (LVP). The LVP was implemented on main runway at 4.10 AM.
