A feasibility study on establishing a snow / ice runway in Antarctica for intercontinental flights by wheeled aircraft, has been undertaken in accordance with an agreement between the Australian Antarctic Division and the Russian Antarctic Expedition. In January - February 1996, a field reconnaissance was made to find a snow / ice runway site in the East Antarctic coastal zone between 60°E and 120°E longitude. Historical meteorological data have been analysed. The temperature range, and wind speed and direction were examined to evaluate the frequency of unfavourable weather conditions at four Antarctic stations: Casey, Zhong Shan, Davis and Mawson. The natural conditions at the four prospective sites near Casey, the Larsemann Hills, Druzhnaya IV and Mawson were investigated to identify the most favourable site in relation to both construction and air operation requirements. Four main criteria were applied to determine the best location for snow / ice runway establishment: (1) the absence of crevassing, (2) the potential for aligning the runway parallel with the prevailing wind with no limiting obstacles in the climb path, (3) the suitability of natural surface gradients, and (4) the suitability of snow stratigraphy and the relation of snow accumulation to melting. The information produced demonstrates that the Casey area is the best place for construction and operation of a compacted snow runway. Another prospective site is on the Amery Ice Shelf near Druzhnaya IV. The equipment and logistic facilities required for compacted snow runway construction are summarised.
