🏢 Terminal Guide & Navigation
Tambolaka Airport, officially renamed Lede Kalumbang Airport in November 2022, is a domestic aviation facility located approximately 5 kilometers from the town center of Tambolaka, the capital of Southwest Sumba Regency on Sumba Island in East Nusa Tenggara, Indonesia. Operating under IATA code TMC and ICAO code WADT, this airport serves as one of only two airports on Sumba Island, providing essential air connectivity to this remote Indonesian island region known for its distinctive culture, traditional villages, and spectacular landscapes.
The airport features a substantial asphalt runway designated 10/28, measuring 2,300 meters in length by 45 meters in width (7,546 by 148 feet), positioned at an elevation of 203 feet above mean sea level. This runway represents the culmination of decades of progressive expansion, beginning with improvements in 1982 to accommodate Douglas DC-3 and Twin Otter aircraft, followed by extensions in 1996 and 2005 to support Fokker aircraft operations, and final expansion by 2015 to enable narrow-body aircraft operations including Airbus A320 and Boeing 737 aircraft.
The airport inaugurated a modern terminal building in 2015, significantly upgrading passenger services from the previous facility. The terminal provides essential amenities including cafes, retail shops, and basic passenger services appropriate for domestic operations. External facilities include dedicated parking areas and taxi stands for ground transportation, connecting passengers to Tambolaka town center and surrounding Southwest Sumba region destinations.
Tambolaka Airport serves as a crucial transportation hub connecting Sumba Island to major Indonesian cities including Denpasar (Bali), Kupang (West Timor), and Surabaya (East Java). Currently, four airlines operate scheduled commercial flights from the airport, with Denpasar and Kupang representing the most popular routes for both tourism and business travel. The airport's strategic importance extends beyond transportation, supporting economic development and tourism growth on Sumba Island while providing essential connectivity for local communities, government services, and emergency transportation needs in this remote region of the Indonesian archipelago.
