An infrared de-icing system is scheduled to be operational late this winter at New York John F. Kennedy International Airport. The system consists of a large tent-like structure under which an aircraft is taxied or towed and de-iced in minutes using the energy generated by hundreds of computer-controlled infrared heating elements. Systems are now in use at Newark International Airport, N.J., Buffalo Niagara International Airport, N.Y. and Rhinelander-Oneida County Airport in Wisconsin. The system will be operated by its developer, Radiant Aviation Services.
