I guess that I'm starting to get back into the swing of things.
Great!

Hey, stumbled across these little gems, made me think about your and Glenn's instrument panels, with the (simulated) Garmin displays:

http://dreamworksrc.com/catalog/34mm...it-p-3404.html

26mm X 34mm....might not quite be 1/4 scale, though. Looking at some Full-Scale Garmin examples, there are various installations, including two side-be-side, aligned "portrait" (versus "landscape") for example...giving about 10 inches total bezel width.

So, the "DreamWorks" units, at about 1 inch by 1-1/3 inch...maybe just shy of true 1/4-Scale?

But, the "WoW!" factor might be worth looking into, if not too late...(or, maybe for next project!!)

Just for comparisons, the EFIS (Electronic Flight Instrument System) PFD screens on the (older) B-757/767 (and older 737s) are cathode-ray, and roughly 6 to 8 inches on the diagonal, in size. Depending on whether the EADI or EHSI.

(Note, all of the warning flags, and no PFD info in that photo means that the Inertial Reference platforms, or "IRSs", are not aligned. Oh, and the 2 center screens, also CRT, are dedicated to the "EICAS"...engine info, and warnings/alerts/messaging).


Updated designs (B-737NG, B-777 and 767-400, and of course the new 787) have larger screens, and use LCD technology. (In fact, there is now an STC to retro-fit older 757/767s to be even more similar to the 787...IF a company wishes to pay the money to have it done!). These are commonly referred to as "MFDs", or "Multi-Function Displays"...you can switch in numerous ways to alter the info displayed on any unit (though, Primary Flight info always has priority, of course). And, there is plenty of redundancy in case of individual screen failures.

Above ^^^ is a (former) CAL, now UAL, B737-900.

Well, I rambled on for long enuf'!!

Cheers, and wishing you a mild winter, for excellent building weather!
