The “Why” behind E3

Aviation Specialties Unlimited's new lightweight night vision goggle E3

This post describes the insights and concerns that spurred the creation of E3, our innovative lightweight night vision goggle.

Limited ANVIS System Improvements:

Over the last 40 years, the ANVIS system has seen minimal advancements, except for incremental improvements in image tube performance (e.g., FOM) and a transition from P43 Green to P45 White output color format.

Contrasting Ground and Aviation NVG Systems:

While ground tactical NVG systems have evolved significantly over the past two decades, introducing features like fused Enhanced Night Vision monoculars/binoculars, lighter binocular systems, and wider field of view formats, aviation night vision systems have experienced only marginal improvements.

Community Concerns – Headborne Weight:

The primary concern expressed by the aviation community regarding the current ANVIS system is the weight and its pull-down effect on the helmet.

2010/2011 User Surveys:

In 2010/2011, the US Army Aeromedical Research Laboratory (USAARL) and the US Army Research Institute of Environmental Medicine (USARIEM) conducted surveys among aircrew members, resulting in the following findings:

  • 2010 Survey Hiatt and Rash et al. (86 Aircrew, 6 months OEF deployment, aggregate of >94,000 flight hours of which ~22,000 are ANVIS):
    • FOV, depth perception, and head-supported weight were the primary drivers of complaints.
  • 2011 Survey Hiatt and Rash et al. (82 Aircrew, OEF deployment, aggregate of >94,000 flight hours of which ~22,000 are ANVIS):
    • High complaints of back and neck pain, with higher and different types of spinal symptoms and man-machine interface issues reported in combat environments.

E3 Weight Reduction Objective:

The E3 initiative aims to significantly reduce the weight of aviation night vision systems through a comprehensive system design overhaul while maintaining high image performance and overall quality, surpassing the current ANVIS system.

Future Focus on Lightweight Equipment:

As aviation night vision progresses, manufacturers should prioritize designing lighter helmets, helmet-mounted displays, and NVG systems. This approach is essential for reducing crew fatigue and providing the best equipment for safe night operations. Every gram matters.
