Paper Abstract

To ensure reliability goals for the 777 display systems are met, Honeywell began a three and one-half year life test of the display backlight systems in July of 1992. To date, sixteen backlight assemblies have accumulated over 12,500 hours of test operation using a luminance profile that is representative of that expected for 777 flight operations. This paper describes design and operating characteristics, life test design, and life test results for the backlight systems of the 777 flight deck displays.
