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.
This SAE Aerospace Recommended Practice (ARP) covers the general requirements and test procedures for illuminating systems for integrally lighted aircraft instruments in order to provide (a) uniformity of illumination within each instrument, (b) legibility of instrument presentation under daylight or integral light, and (c) uniformity of illumination between instrument displays.
This SAE Aerospace Recommended Practice (ARP) lists the lamps in Table 1 that are recommended for the type of service indicated. This list is not intended as a catalog and does not include many types that are now in use. It does, however, reflect current practice.
The scope of this ARP is to provide general requirements for application of electroluminescence to Aerospace Vehicle Crew Station Area instruments and control panels. The design brightness and color recommendations stated in this ARP are intended to apply where a crew station has multiple usage of electroluminescence in both instruments and control panels and when different manufacturers may be involved. These recommendations may also be helpful for the design of individually used displays incorporating electroluminescence, however, this light source has extensive design versatility through variance of manufacturing and operating parameters and the numerous acceptable design recommendations will not be stated herein. Electroluminescence will herein be referred to as EL.
This ARP covers the recommended requirements for the lighting and characteristics of instruments; information plates and displays; emergency, cautionary, advisory and status displays; circuit breaker and toggle switch positions; and the recommended requirements for the utility lighting system.
This ARP describes methods for measuring the visual performance of direct view cathode ray tube displays used in aircraft flight decks and cockpits. Procedures may vary depending upon the type of display (for example, monochrome, color shadowmask, beam index, etc.), but all types are considered.
