Book Description
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.

Book Description
Cockpit lighting in U.S. Army helicopters was investigated for compatibility with use of night-vision goggles, AN/PVS-5. Instrument-lighting systems in existing Army helicopters, e.g., eyebrow lighting, post lighting, are not suitable for use with night-vision goggles. A comparatively simple flood- lighting system can provide suitable lighting in the cockpit of existing helicopters for reading instruments with night-vision goggles. The most suitable instrument-lighting system for use with the goggles is integral instrument lighting; however, indicator lights need to be modified so they are compatible with the goggles. Methods were investigated for instantaneously refocusing the goggles inside the cockpit. Luminance levels compatible for use with night- vision goggles are stated in photometric terms.

Book Description
Cockpit lighting can interfere with the proper operation of night vision goggles (NVGs) in several specific ways. For each interference mechanism, the effect on the image seen through the NVGs is to reduce the brightness of portions of the image and/or reduce the contrast of the useful image (the view outside the aircraft). This reduction in brightness or contrast may be manifested as a reduction in visual acuity and/or as an observed loss of contrast or brightness. AFRL/HECV was requested by the FAA (this research effort was jointly funded by the FAA and AFRL/HECV) to investigate low-cost, alternative methodologies that can be used by civil aviation to evaluate NVG cockpit lighting compatibility. In order to facilitate the inexpensive evaluation of cockpit lighting interference with the operation of the NVGs, a field evaluation kit was developed. This kit makes it possible to conduct a low-cost version of the standard visual acuity test method currently used by the Air Force. This report describes the fabrication, components, and implementation of this field evaluation test kit, which was recommended to and delivered to the FAA.

Book Description
"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

Book Description
This report describes recommended methods for scanning the flight path and cockpit instruments for pilots wearing night vision goggles (NVGs) while flying Army helicopters. The impetus for this report was a task force sponsored by the Office of the Deputy Chief of Staff of the Army for Plans and Operations, which determined that the development of scanning methods was the Army's top training priority for night helicopter operations. The recommended methods of scanning were derived from published scientific works, interviews with scientists, and interviews with aviators from field tactical units, training units, and from the research and development community. The proposed scanning methods recommend free search as opposed to formalized scan patterns. In addition, they place equal weight on crew coordination and individual technique. The proposed methods stress actions taken before flight, such as premission planning and NVG preflight adjustments. Furthermore, the proposed methods are intended to build an awareness of: NVG performance limits, and how to maximize performance; common problems encountered while scanning with NVGs, and the conditions which elicit them; and the scientific basis for scanning. Separate scanning methods were developed for individuals and for crews. In addition, the relevant scientific literature was reviewed.
