Which of the following properties should the sunglasses of a pilot have?
SUNGLASSES IN THE COCKPIT
Sunglasses play a crucial role in protecting a pilot's vital sensory asset: their vision. In the cockpit, high-quality sunglasses are a necessity to enhance visual performance. They mitigate the impact of intense sunlight, alleviate eye fatigue, and shield the eyes from detrimental solar radiation. Additionally, sunglasses assist in the adjustment to darkness, which can be impeded by extended exposure to bright sunlight.
- Polarised lenses decrease light transmission by selectively filtering specific electromagnetic planes. These lenses can create distortion patterns on laminated cockpit windshields, alter the appearance of clouds, and diminish ground reflections, which are valuable for VFR pilots. Consequently, the use of polarised sunglasses is NOT recommended.
Note: UV filter is needed to prevent cataracts.
