When I ordered the FDS MIP I knew it came with IBL backlighting and to be honest and I didn’t give it much thought. I had seen panels lit in various ways in the past, be it LED, LED strips, Cold Cathode and even a lightbulb (I imagine the heat that gave off would help warm the cockpit). In real life general aviation flying I have seen aircraft lit with post lights, backlighting and a mix of the two. I have cancelled night flights because the quality of the backlighting was so poor I could barely read the instruments, while the radio was so bright in nearly blinded me. Though I have worked for Boeing in the past, I had limited exposure to finished commercial flight decks, but was impressed with the consistent quality of the lighting of those that I did see (Military derivatives of the 737 and 767 models).
So today was the first chance I have had to wire up the backlighting on the FDS MIP panels. WOW, these are impressive! Clear, readable text, warm, glowing backlighting that is consistent across not only the different panels, but all the lettering on eeeach panel. No dim spots or blurry text like some I have seen. FDS achieves this through the use of 5v Aircraft Bulbs and their patented process. Whatever it is, I’m sold. No doubt in my miond now which overhead panels I will be ordering!
Keep in mind, that because these are 5v and there are a lot bulbs, they can pull some amperage, so don’t try powering them from a low amperage source.
Off to finish wiring up the rest of the panel but here’s a few photos to give you a taste…
