"The requirements to assess the compatibility of aircraft cockpit lighting with night vision goggles (NVGs) are defined in MIL-L-85762A. Lighting, Aircraft, Interior. Nifiht Vision Imaging System (NVIS) Compatible. However, the procedures specified to evaluate cockpit lighting are primarily specific to the laboratory environment, with only a few assessments specific to the field environment. This report describes the procedures used by Armstrong Laboratory's Aircrew Training Research Division (AL/HRA) to conduct a field evaluation of aircraft cockpit lighting. The evaluation procedures are divided into Planning, Evaluation Preparation, Assessment Procedures, and Reporting Results. This report can also be used as a guideline for other organizations that need to conduct NVG-compatible cockpit lighting evaluations."--Page ii

"This research examined the capabilities of virtual environments to simulate night vision goggle (NVG) effects. Different solutions for simulating NVG images were assessed. Two conditions simulated NVGs but used different software approaches. Two additional conditions simulated unaided night environments that required soldiers to wear NVGs. Four-man infantry teams conducted urban operation missions under each condition. Objective assessments were obtained on the number of events correctly detected and the average time required to detect an event. Subjective assessments of task difficulty and image fidelity were also made. No significant differences were found across night conditions for either event detection or time. Significant differences in task difficulty ratings occurred for movement, visual detection, and maintaining situation awareness. In general, tasks were more difficult to perform while wearing the NVGs compared to simulated versions of NVG images. Soldiers also ranked the conditions involving actual NVGs as more realistic. The unique contribution of virtual environments for night operations training may be at the entry level. However, specific image fidelity issues associated with the use of NVGs in simulated unaided night environments must be addressed if this approach is to be used as an effective training medium."--Stinet.

Integrating NVGs into aircraft with incompatible interior designs limits performance and presents safety and operational concerns to the flying communities. Non- ejection safe NVGs and their corresponding carrying case presents a space dilemma forcing pilots to contend with where to safely store the goggles. An example of this occurred when the carrying strap entangled the flight controls of an A-10. Interior aircraft lighting not compatible with the spectral sensitivity of NVGs presents another concern. The prohibitive cost of aircraft modifications has resulted in the application of frequent "quick-fix" solutions. An effective lighting-fix was implemented in the cockpit of the B-1 bomber, but the problem persisted due to non-modified lighting from the aft stations. Aircraft System Program Office s (SPO), attempted to solve this problem by proposing the installation of a light-blocking curtain, separating the two compartments. Fabric samples for the proposed curtain were evaluated to determine the fabric which met the criteria. In the interest of reducing weight and maximizing battery life, NVG manufacturers and field units for the most part, have transitioned from alkaline to lithium batteries. However, with the use of lithium comes environmental, cost, and shipping concerns. The results of a comparative study on various batteries will be presented.
