NEW DELHI, Feb. 3 (Xinhua) -- Authorities at the Indira Gandhi International Airport in Delhi on Saturday began to upgrade the second runway to ensure smoother operations in adverse weather conditions.
The move will provide relief to passengers experiencing flight delays in winter due to dense fog at Delhi airport.
According to officials, the runway has been equipped with CAT III technology, which will ensure secure landings during extremely poor visibility.
The upgrade would ensure further mitigation of weather-related congestion issues, India's Civil Aviation Minister Jyotiraditya Scindia said in a statement.
CAT III (technically called Category III) is an advanced set of instrument landing system capabilities that allow aircraft to land in very low visibility conditions, including dense fog, heavy rain, or snow. The system helps with a precision approach and landing when runway visibility level is low.
Recently, flights at the airport were delayed for days because of dense fog. ■
