Flights of almost all the international airlines and domestic airlines were affected on Monday due to low visibility at the Tribhuvan International Airport (TIA) in Kathmandu owing to bad weather.
Terminal Duty Office (TDO) at TIA asked Air Arabia, Turkish Air, Spice Jet, Biman Bangladesh, Indian Airlines, Fly Dubai and Korean Air, among others, to hover in the sky for around an hour after thick fog reduced visibility at the county’s only international airport.
After hovering in the Nepali sky for about an hour, Turkish Airlines was asked to divert to New Delhi. “Though the airline came back after the weather improved, it was again diverted to Lucknow as landing was impossible due to low visibility,” an official of TDO Republica.
Similarly, Fly Dubai was diverted to Lucknow.
Qatar Airways, however, landed on time using required navigation performance-authorization required (RNP-AR) navigation technology.
Birendra Prasad Shrestha, acting general manager of TIA, most of the international flights were asked to hover in the sky due to dense fog.
“Besides, the aircraft of Indian Airlines, Spice Jet and Nepal Airlines were grounded due to some problems,” Shrestha said, adding, “In addition to that, an aircraft of United Nations occupied four of the nine parking bays of the airport, forcing us to put some flights on holding pattern for some time.”
Number of domestic flights were affected on the day as the airport opened at around 11 am only. This forced Buddha Air, Yeti Airlines, Tara Air and Simrik Air to cancel some of their. Likewise, all the mountain flights were also cancelled.
International airlines operate flights only when visibility is above 2,800 meters. On Monday morning, TIA had ground visibility of only around 500 meters.
