Passengers are advised to keep themselves updated through official airline communication channels, allow extra time for airport arrival and check-in procedures and plan their travel accordingly,” it said.Air India also issued a statement during the day, saying, “The weather forecast continues to indicate dense fog with significantly reduced visibility in Delhi and parts of North India tomorrow morning. We understand how frustrating such disruption to travel plans can be and are making all possible efforts to minimize the inconvenience,” it said, while explaining its ‘FogCare initiative’ to help passengers. As per the DGCA norms for fog operations (CAT-IIIB), airlines are required to deploy pilots trained to operate in low visibility conditions and operate aircraft that comply with CAT-IIIB standards. Category III refers to an advanced instrument landing system that allows aircraft to operate in fog. Category III-A is a precision approach and landing system that allows operations with a runway visual range (RVR) of up to 200 meters, while Category III-B allows landings when the RVR falls below 50 meters.
