As many as 66 flights were cancelled at the Delhi Airport on Friday because of fog and low visibility. Several airlines cancelled 66 flights to and from Delhi for the same reasons, according to a source. Of those, 32 were arrival flights, and the remaining 34 were departures.
The aviation regulator DGCA has declared the period from December 10 to February 10 as the official fog window for this winter.
66 Flights Cancelled at Delhi Airport due to fog
According to DGCA’s flight operation rules during fog, airlines must assign pilots trained to operate in low visibility. They also need to use a CAT-IIIB-compliant aircraft fleet for these operations.
Category-III is a navigation system that allows aircraft to land in foggy conditions. Category-III-A is a precision approach that enables a plane to land with a runway visual range (RVR) of 200 meters, while Category-III-B allows landing with an RVR of under 50 meters.
