New Delhi: After remaining normal for two days, operations at the Indira Gandhi International (IGI) airport here on Monday were hit due to dense fog which affected schedules of over 50 flights.
Arrival or departure of around 20 flights were cancelled either due to operational reasons or due to bad weather conditions, airport officials said. Among the flights arriving here which were cancelled were from Bagdogra, Pune, Lucknow, Mumbai, Patna and Chandigarh.
Air India flight AI 996 from Dubai was diverted to Mumbai at around 4.50 AM, when visibility dropped below 50 metres, as the aircraft was not CAT-IIIB certified for instrument landing.
To operate in dense fog conditions, an aircraft has to be CAT-IIIB complaint along with its cockpit crew. The aviation regulator Directorate General of Civil Aviation has to certify an aircraft declaring it fit to operate under poor visibility conditions.
