The Visor Re-envisioned
Bright sunlight conditions pose various challenges in the cockpit. In addition to limiting pilots’ vision, extreme illumination may alter the visibility of Helmet Mounted Display symbology and video presentation. Existing solutions entail a dual visor operation, requiring a manual, in-flight visors change.
Elbit Systems’ Variable Transmittance Visor (VTV) is coated with an advanced photochromic layer that uses proprietary technology to dynamically limit the passage of light according to intensity. As the visor automatically adapts to the intensity of the light, a clear view of the cockpit, the outside world and the display is maintained at all times, allowing pilots to fly with a single adaptable visor for all light and weather conditions.
Key benefits
After extensive evaluation, the results show VTV offers:
- Full operational performance 24/7 ultra-thin layer
- A single visor for both day and night missions
- Can reach more than 85% and higher transmission for night missions
- Can go as low as 15% light transmission in bright sunlight environment
- No manual, in-flight visors change
- Enhanced pilot comfort
- Reduced head-borne weight
