Abstract: System for applying compounds protective against ice formation on airplanes and for also cleaning and washing at respective first and second locations of at least one unitary covered structure. The unitary covered structure can be at least seasonally, or more often as requirements dictate, shuttled between a location immediately adjacent the clear zone of a runway for cold weather, or storm, operations and a location remote from said clear zone for washing in warm weather operations. Both positions of the covered structure have dedicated supply and drainage system for the fluids supplied at each position. Several unitary covered structures of various dimensions at several locations adjacent to the clear zone of a runway are also shown.
