This book was released on 2003 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is a compilation of spectral transmissivity data measured from numerous aircraft transparencies. The spectral transmissivity of each part was measured from wavelengths of 450 nm through 950 nm. Some parts were also measured at several different angles relative to the optical axis of the spectroradiometric instrument. The measurements yielded both visible light and near infrared (NIR) spectra. The NIR data were used to calculate night vision goggle-weighted transmissivity (TNVG) values (Pinkus and Task, 1997). TNVG is a measure of a transparency's compatibility when it is used in conjunction with night vision goggles (NVGs). NVGs utilize the NIR portion (600 nm through 950 nm) of the night sky ambient illumination. Generally speaking, the higher the TNVG coefficient, the higher the NVG visual performance (Pinkus & Task, 1998a; Pinkus & Task, 1997).

Book Synopsis The Effects of Aircraft Transparencies on Night Vision Goggle-Mediated Visual Acuity by :
Download or read book The Effects of Aircraft Transparencies on Night Vision Goggle-Mediated Visual Acuity written by and published by . This book was released on 1997 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Night vision goggles (NVGs) are currently used in a wide variety of military aircraft that were not originally designed for NVGs. Likewise, the windscreens and canopies on these aircraft were not designed with NVGs in mind. Present day windscreens and canopies typically have one or more specialized coatings applied to them. These may be reasonably transparent for visible wavelengths but not so transparent for near infrared light to which the NVGs are sensitive. It was hypothesized that the major mechanism by which aircraft transparencies affect the operation of NVGs is through reduced light levels. This would mean that the key characteristic of interest for determining the effect of an aircraft transparency on the operation of the NVGs would be its transmission coefficient calculated using the spectral sensitivity of the NVGs. This hypothesis was tested by investigating visual acuity performance of trained observers viewing through NVGs for three levels of ambient illumination (1, 2 and 5 times starlight) and three levels of NVG- weighted windscreen transmissivities (58, 76 and 100%). In addition, two levels of contrast were included in the study (20 and 70% modulation contrast). Three trained observers determined the orientation of a Landolt C using a two-alternative, forced-choice step paradigm. A luminance-based model was developed to smoothly combine the effects of illumination level and transmission level for each contrast thus supporting the hypothesis. In addition, the results demonstrate the significant difference between individual observer's performance level and the increased difficulty (higher variability) of performance at lower contrast levels.

Pinkus and published by . This book was released on 1998-03-01 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several ASTM Standards that address light transmissivity through transparencies (ASTM Standards F 1316-90D and 1003-61) in the visible spectrum (400 through 700 nm). However, night vision goggles (NVGs) are now being used in aircraft and other applications (e.g., marine navigation, surveillance, personnel carriers) with increasing frequency. These devices amplify both visible and near-infrared (NIR) spectral energy. A transparency may have excellent visible transmissive characteristics but could have poor NIR transmissivity. Overall visual performance (acuity) can be degraded if the observer uses the NVGs while looking through a transparency that has attenuated transmissivity in the NIR region (Pinkus and Task, 1997, see Appendix A). ASTM P94-02, Standard Test Method for Measuring Night Vision Goggle-Weighted Transmissivity of Transparent Materials (see draft in Appendix B) addresses this issue.

This book was released on 1993 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Night Vision Programs Office of the Aircrew Training Research Division, Armstrong Laboratory, responded to a request from the 422nd Operational Test Squadron at Nellis AFB to conduct the ground testing portion of their A-10 Night Vision Goggle (NVG) special project. Evaluations were conducted comparing the performance of four different NVGs under both laboratory and representative operational conditions. The performance of the F4949 'Super ANVIS' was superior to that of the other NVGs tested. Additionally, a comparative study was conducted evaluating the impact of two different windscreens on NVG image quality. The new windscreen allowed the transmission of more energy usable to the NVGS, thus enhancing image quality over that possible with the old windscreen ...

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Standard (AS) will specify what type night vision goggles are required, minimum requirements for compatible crew station lighting, aircraft exterior lighting such as anticollision lights and position/navigation lights that are "NVG compatible." Also, this document is intended to set standards for NVG utilization for aircraft so that special use aircraft such as the Coast Guard, Border Patrol, Air Rescue, Police Department, Medivacs, etc., will be better equipped to chase drug smugglers and catch illegal immigrants, rescue people in distress, reduce high-speed chases through city streets by police, etc. Test programs and pilot operator programs are required.For those people designing or modifying civil aircraft to be NVG compatible, the documents listed in 2.1.3 are essential. This document is being revised for the references for the Code of Federal Regulations (CFRs) to be corrected to Part 14 Code of Federal Regulations (14 CFRs). Added FAR requirements to reference section and allowance on non-GEN III goggle use.

Book excerpt: In July of 1999 the Air Force Research Laboratory (AFRL) took delivery of the last of twelve panoramic night vision goggle (PNVG) systems. Data on these systems has been collected onboard a variety of aircraft including the F-15C, F-15E, F-16, A-10, F-117, C-17, C-5, C-130, and HH-60 aircraft. Data will continue to be collected on these aircraft as well as other platforms over the next 12 months In April of 2000 a follow-on development effort was initiated entitled 'Integrated Panoramic Night Vision Goggle' (I-PNVG). Lessons learned from the PNVG effort are being incorporated into the I-PNVG program wherever possible. Specific objectives to be addressed under I-PNVG effort are wide field-of-view, integrated laser protection, fit/comfort, image quality, integrated symbology/imagery display, field support, ejection/crash/ground egress safety, compatibility with existing systems, affordability, supportability, maintainability, producibility, and reliability. This paper will briefly discuss pilot comments about the PNVG, provide further detail of the I-PNVG objectives, and address I-PNVG design considerations.

Book Synopsis Human Performance and Limitations in Aviation by : R. D. Campbell
Download or read book Human Performance and Limitations in Aviation written by R. D. Campbell and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human error is cited as a major cause in over 70% of accidents, andit is widely agreed that a better understanding of humancapabilities and limitations - both physical and psychological -would help reduce human error and improve flight safety. This book was first published when the UK Civil AviationAuthority introduced an examination in human performance andlimitations for all private and professional pilot licences. Nowthe Joint Aviation Authorities of Europe have published a newsyllabus as part of their Joint Aviation Requirements for FlightCrew Licensing. The book has been completely revised and rewritten to takeaccount of the new syllabus. The coverage of basic aviationpsychology has been greatly expanded, and the section on aviationphysiology now includes topics on the high altitude environment andon health maintenance. Throughout, the text avoids excessive jargonand technical language. "There is no doubt that this book provides an excellent basicunderstanding of the human body, its limitations, the psychologicalprocesses and how they interact with the aviation environment. I amcurrently studying for my ATPL Ground Exams and I found this bookto be an invaluable aid. It is equally useful for those studyingfor the PPL and for all pilots who would like to be reminded oftheir physiological and psychological limitations." –General Aviation, June 2002
