Flights and trains hit as fog engulfs Delhi-NCR

New Delhi: Delhi-NCR was engulfed in a thick layer of fog on Wednesday morning with the minimum temperature dropping to 7 degrees Celsius, a notch below normal.

Flight and train operations were affected as visibility dropped. The humidity level was 100 per cent, while the visibility was 50 metres.

The bad weather conditions in Delhi delayed more than 30 departures as visibility dropped below 150 metres. According to an airport official, five flights diverted as the captains were not trained to land under CAT conditions. When the runway visual range (RVR) is minimum 200 metres, only a pilot trained in instrument landing system Category 3A (CATIIIA) can land the aircraft. If the RVR is minimum 50 metres, a pilot who is trained in using CATIIIB landing system can land the aircraft at the airport.

According to the Central Pollution Control Board (CPCB), the air quality index (AQI) in New Delhi on Wednesday was 376 at 8 am which falls in the ‘very poor’ category.
