Three runways at the IGI airport 28, 29 and 11 are certified for CAT III B operations, which would allow landing of the compliant aircraft with visibility as low as 50 meters, the officer said. For take-off, an aircraft would require a visibility of at least 125 meters. He further said that information related to the delays and cancellations were updated time to time at the Delhi Airport’s website to keep the passengers updated.
