New Delhi: With the onset of winter, temperature dipping down and the increasing number of vehicles running on diesel, the atmospheric level is getting heavily polluted. Taking note of such a situation, the Directorate General of Civil Aviation (DGCA) has asked the Delhi Airport authorities and the airlines operating from here to step up their anti-fog arrangements.

As per the predictions of the Indian Meteorological Department, foggy conditions would prevail over Delhi between December 20 and February 20 during which there would be an estimated 110 fog hours.

In this regard, DGCA Chief E K Bharat Bhushan on Wednesday reviewed the preparedness of all airlines, Delhi Airport operator DIAL and other agencies to meet the exigencies and ensure that minimum hardship is caused to the travelling public.

Besides, he also instructed the airlines to ensure the availability of adequate number of trained pilots to operate in dense fog situations, especially during the takeoff and landing time of the airlines at the Delhi airport. For which, the airlines would have to ensure enough number of pilots, trained to operate a flight using the Category-III Instrument Landing System, to and from Delhi.

Two additional alternative airports at Udaipur and Bhubaneshwar have been designated to cater to diverted flights destined to Delhi and Kolkata respectively. In the northern region, alternate airports include Lucknow, Jaipur and Amritsar.

The airlines were also asked to provide advance information to passengers about flight delays, rescheduling or cancellations through SMS, email or phone, they said, adding that latest met information should be displayed on the Flight Information Display boards at the airports and updated every 15 minutes.

On facilities to be provided to passengers, the DGCA chief asked all airlines to ensure basic amenities, along with food, at alternate airports in case a flight is diverted.

The meeting also decided that all construction work should be stopped near the operational area of the IGI Airport. DIAL should also ensure that adequate number of ‘follow-me’ jeeps is available during fog.

When the fog situation improves, priority should be given by the Air Traffic Control (ATC) to the diverted flights.
