Plain English Meaning
A foggy or cloudy look in the windshield or windows that makes it harder to see through them clearly.
Full Definition
A milky, cloudy, or fogged appearance in transparent material such as an aircraft windshield or window, caused by fine scratches, age, weathering, chemical exposure, or improper cleaning, which scatters light and reduces visibility through the surface.
Context Anchor
Seen during the visual preflight inspection when checking the windshield, side windows, canopy, and exterior light covers.
Derivation
From the English word 'haze,' meaning a thin mist or cloudiness in the air. Applied to windows, it describes a similar foggy, scattered look in the material itself rather than in the air.
