This article discusses the major points that must be considered when evaluating the practicality of fog dispersal systems. Fog forms in several ways and can be classified as radiation (ground fog), adviction, frontal, and upslope. Considerable success has been achieved in dispersing supercooled fogs because supercooled fogs droplets can be converted into snowflakes which fall to ground. Warm fogs can be heated to evaporate the fog droplets. It is noted that 95% of the fogs that disrupt airline operations are warm fog types. In evaluating the feasibility of fog clearance, it is important to consider fog climatology, schedules of aircraft operations, the physical characteristics of the airport, cost of installation and operation of equipment, and environmental effects. Some consideration should also be given to local sources of pollution which may produce nuclei increasing the frequency of fog formation. Although fog dispersal appears to be technically feasible, a thorough cost/benefit analysis is a determinant in any plans for a program to enhance visibility in fogs at an airport.
