The aviation watchdog DGCA designated 10 December 2025 to 10 February 2025 as the official fog window for this winter. It urged airlines to follow CAT-IIIB low-visibility operating norms. Airlines were instructed to mandatorily roster pilots trained to operate in low-visibility conditions. Further requirement for this period entails use of CAT-IIIB-compliant aircraft fleet.

Category IIIB-compliant aircraft are those planes that are equipped with specialized technology to enable landings at a runway visual range of 50 meters. Meanwhile, CAT-III A allows landings at a runway visual range of 200 meters due to its precision instrument.
