Aircraft transparencies are susceptible to numerous optical characteristics which may impact the visual performance of the aircrew. These characteristics range in severity from simply distracting to hazardous. This report describes and illustrates the ten most common of these optical characteristics. It may be used as a guide by aircrews, maintenance personnel, and others working with transparencies to assist them in accurately identifying transparency optical defects.
