This document is intended to highlight critical design issues that a panel designer should understand when designing panels for NVIS applications. It is not intended to be a discussion of the benefits of one lighting technology versus another. See ARP4168 for a more complete discussion of these lighting technologies. The primary justification for the revision change is to reflect the change of AS7788 to MIL-DTL-7788. Other changes were made to improve the overall document.

Renamed to reflect the increased role of digital electronics in modern flight control systems, Cary Spitzer's industry-standard Digital Avionics Handbook, Second Edition is available in two comprehensive volumes designed to provide focused coverage for specialists working in different areas of avionics development. The first installment, Avionics: Elements, Software, and Functions covers the building blocks and enabling technologies behind modern avionics systems. It discusses data buses, displays, human factors, standards, and flight systems in detail and includes new chapters on the Time-Triggered Protocol (TTP), ARINC specification 653, communications, and vehicle health management systems.
This SAE Aerospace Recommended Practice (ARP) reviews the basics of NVIS compatibility and discusses the specific illuminated pushbutton switch and indicator requirements for sunlight readability, color, luminance, and NVIS radiance when used in NVIS compatible cockpits.The recommendations and special considerations set forth in this document are made to give the design engineer a better understanding of MIL-L-85762A and MIL-STD-3009 NVIS compatibility requirements and to provide information on the visual characteristics of NVIS compatible pushbutton switch and indicators. The recommendations are primarly for military aircraft since civilian aircraft FAR requirements typically do not cover NVIS applications with the exception of those covered by RTCA/DO-275. Warning, caution and advisory push-button switches and indicators are considered by pilots to be one of the most important items in the aircraft crew station. With well defined and historical application of aviation color requirements, these push-button switches and indicators can be particularly difficult to achieve in an NVG green-lighted compatible crew station with chromaticity limits now defined by military specifications that are lacking in most FAR documents. This specific technology, which is utilized to deal with the design of these devices is covered in this document. The most recent revision to is update the references, add Class C response curve and to correct some photometric and radiometric requirements.
Avionics provide crews and passengers with an array of capabilities. Cockpit crews can operate with fewer pilots, greater efficiency, and immediate critical information. Passengers can enjoy the ultimate in inflight entertainment: live television and audio broadcasts and access to the Internet and e-mail. Since avionics are the among most ex
Now available in a three-volume set, this updated and expanded edition of the bestselling Digital Signal Processing Handbook continues to provide the engineering community with authoritative coverage of the fundamental and specialized aspects of information-bearing signals in digital form. Encompassing essential background material, technical details, standards, and software, The Digital Signal Processing Handbook, Second Edition reflects cutting-edge information on signal processing algorithms and protocols related to speech, audio, multimedia, and video processing technology associated with standards ranging from WiMax to MP3 audio, low-power/high-performance DSPs, color image processing, and chips on video. The three-volume set draws on the experience of leading engineers, researchers, and scholars and includes 29 new chapters that address multimedia and Internet technologies, tomography, radar systems, architecture, standards, and future applications in speech, acoustics, video, radar, and telecommunications. Each volume in the set is also available individually ... Emphasizing theoretical concepts, Digital Signal Processing Fundamentals (Catalog no. 46063) provides comprehensive coverage of the basic foundations of DSP. Coverage includes: Signals and Systems, Signal Representation and Quantization, Fourier Transforms, Digital Filtering, Statistical Signal Processing, Adaptive Filtering, Inverse Problems and Signal Reconstruction, and Time–Frequency and Multirate Signal Processing. Wireless, Networking, Radar, Sensor Array Processing, and Nonlinear Signal Processing (Catalog no. 46047) thoroughly covers the foundations of signal processing related to wireless, radar, space–time coding, and mobile communications together with associated applications to networking, storage, and communications. Video, Speech, and Audio Signal Processing and Associated Standards, (Catalog no. 4608X) details the basic foundations of speech, audio, image, and video processing and associated applications to broadcast, storage, search and retrieval, and communications.
This SAE Aerospace Recommended Practice (ARP) describes the recommended performance levels for equipment located on the aircraft exterior which produces radiant energy which will provide desired information when viewed with NVIS goggles.These performance intensities, normally stated in candelas for visible light, are modified to consider the goggle spectral response range. Where necessary, location of the equipment on the airplane is specified.The spectral emission characteristics may or may not include visible light. Whether or not visible energy is emitted, this document will refer to these items of equipment as "lights". ARP4392 has been reaffirmed to comply with the SAE Five-Year Review policy.
The use of Night Vision Imaging Systems (NVIS) by military aviators has had a major impact on the design and integration philosophy of interior and exterior lighting systems. The integration of NVIS exterior lighting systems to meet the associated mission requirements is in the early stages of development. Operational performance and military specification requirements have not been updated and established. This technical memorandum presents information and lessons learned from development, test, and evaluation (DT and E) support of the A-12 program and development of test procedures to evaluate exterior lighting systems. During the DT and E support of the A-12 program, major exterior lighting issues had to be resolved. This evolution generated experience associated with exterior lighting and NVIS performance requirements. The information presented is not all inclusive but contains information to be used for updating exterior lighting Military Specifications requirements and test procedures. The additional integration requirements and design considerations will improve the utility of NVIS thus improving aircraft combat survivability and performance for various mission requirements.
