ТУ 21-УССР-008-77.

 

It is an element intended for a visual observation while flying the aircraft. The pilot cabin glazing set consists of two elements (right- and left-side ones) provided with documentation. This type of glazing is a triplex

consisting of two silicate glass planes (inner and outer ones) held together by a polyvinyl butyral film. The triplex is also rimmed by sealant with glass cloth or harness.

Electrical heating is performed through current-conducting coating applied to the inner side of the outer glass. Heating control can be mediated by temperature controller ТЭР-1.
