Troll Airfield
Troll Airfield is an airstrip located from the research station Troll in Princess Martha Coast in Queen Maud Land, Antarctica. Owned and operated by the Norwegian Polar Institute, it consists of a runway on glacial blue ice on the Antarctic ice sheet. The airport is located at above mean sea level and is from the coast.
The airfield opened in 2005 and serves as the centre of the Dronning Maud Land Air Network (DROMLAN), a multinational cooperation to use Troll as an all-year hub to provide intercontinental traffic to Antarctica and onwards to the various research stations using aircraft suitable for inter-Antarctic operations. Intercontinental flights normally operate from Cape Town International Airport using Ilyushin 76, C-130 Hercules, P-3 Orion and similar, long-range aircraft. Feeding services to other research station is normally done either with Basler BT-67 aircraft, De Havilland DHC-6/300 Twin Otter aircraft and Dornier Do-228 aircraft and helicopters.

Troll Airfield is located from Troll in Princess Martha Coast in Queen Maud Land, Antarctica. It is owned and operated by the Norwegian Polar Institute and consists of a runway on glacial blue ice. This allows it to be used by any aircraft serving the Antarctic. There is no Instrument landing System - ILS, instead visual flight rules - VFR apply. There are no buildings or structures at the runway, although some services are provided from the research station. Ground handling, including supply of Jet A-1 fuel, is provided by the crew at Troll. The crew also supply services such as a fire and rescue service, communications and overnighting at Troll for personnel who would be stuck because of bad weather.〔Kyvik et.al (2008): 173〕 The airfield must follow the Protocol on Environmental Protection to the Antarctic Treaty. This includes storing all fuel in barrels and large tanks placed on special mats which absorb liquids, to avoid spills. There is also equipment and plans to handle spills, should they occur. All waste is transported out of the Antarctic.
The airfield has a cold and dry climate, being located in a desert. The annual mean temperature is , with the summer temperature able to reach about and the lowest during the winter at . Storms, which can occur throughout the year, can occasionally make outdoor activity impossible. Because it is located south of the Antarctic Circle, Troll has midnight sun in the summer and polar night during the winter.〔
