Chapter 4 - Preventative Measures and Deicing Procedures

Alternate Technologies

93.  The cost and potential environmental impact of deicing with conventional fluids, has driven the demand for the development of alternate deicing technologies. When considering the benefits of these technologies, it is important to understand that while the methodology may differ from that used with conventional fluids, the basic principles of de/anti-icing still apply. Recent technologies employ such scientific principles as: the latent heat of fusion; the sensing of vibrating elements; the employment of ultrasonic sensors; and the use of infrared (IR) detection cameras. Other technologies will no doubt evolve with time.
