A customer called to ask, ‘what type of light and which color would work best in a glass cockpit?’
The short answer is soft white – unless your flying with night vision goggles, in which NIVIS White (best) or NVIS Green.
The real issue is glare. Included is a picture of the GNS 750 and one installed in a C206. The C206 is a good example of mixed cockpit, some glass, some standard instruments. Most of the controls and bezels though still require additional lighting. The glass itself has a great anti-glare coating, and the new displays are great for daylight reading, so a FLITELite set to moderate intensity is not going to challenge the display or reflect in any appreciable manner. This is also due to the filter we use, and the soft white LED we select that is cooler than daylight.
Consider the use of paper charts – still using them? What about circuit breakers when things go dark, or even in when the don’t, night time can make them though to identify. Placards, standby gauges, overheads, and controls (especially sticks that have multiple buttons) are places where even glass cockpits need some extra light.
