The Directorate General of Civil Aviation (DGCA) has issued a show-cause notice to Air India and SpiceJet for rostering pilots who are not trained in CAT III technology, which assists planes in landing during dense fog and inclement weather conditions when visibility is low.
The aviation regulator issued the notice after more than 50 Delhi airport-bound flights were diverted due to low visibility on December 24-25 and December 27-28, as stated by the DGCA.
Dense fog covering the national capital and adjoining areas in the past few days has led to the diversion of several Delhi-bound flights, with visibility dropping to as low as 0-50 meters at times.
The CAT III technology, an Instrument Landing System (ILS), is a navigation system that guides airplanes to the runway during low visibility conditions like fog, snow, or heavy rain.
It enables landings with a visibility of 200 meters and a ceiling of 60 meters, thereby minimising the need for flight diversions.
