Human Machine Interface Products
Human Machine Interface products are used throughout the cockpit to provide information and control of aircraft systems. Our illuminated products offer this capability for both day and night operations and can be adopted for use in night vision applications (NVG / NVIS).
HMI products are known by several names and technologies including Lightplates, Lighted Panels, Keyboards, Illuminated Keyboards, Glareshields, Glareshield Lights, Floodlights, Post Lights, Control Panels, Electronic Assemblies, Annunciator Panels, Indicator Panels, Circuit Breaker Panels, etc.
Lightplate and keyboard details
AMONG THE MOST COMMON HMI PRODUCTS
Lightplates and Keyboards are among the most common HMI products integrated into the cockpit directly or as part of another aircraft system. These specialized products are highly engineered and defined by common industry accepted performance characteristics. While the following general specifications are frequently requested, there are often cases when mission specific requirements are needed. Radiant Power is here to help with your needs … standard or uncommon.
