Transparent LCD cockpit window with Synthetic Vision?
Transparent LCD cockpit window with Synthetic Vision?
LG shows off 18-inch flexible, transparent OLED display - SlashGear
These are flexible, so replace aircraft windows with these and project whatever, flight data, synthetic vision, Infrared visuals. Like a large, color Head Up Display.
The image of the outside world in this picture for example, could be replaced by a synthetic vision version : imagine the lake and mountains is just a digital image and not really the outside world. A lot of area to project flight instrument data as well.

It could also display movies for pilots on long haul flights...

Why? What benefit is there in replacing windows with a screen that replicates a window?
However, in IFR conditions, when all you see outside is white or black or grey for that matter, the LCD 'window' will be switched on, and it will display:
1) Infrared visuals such as in the video here:
Gulfstream Aerospace - Technology - Vision Systems
2) Synthetic Vision display
Windowless cockpits have been suggested.
Airbus patents windowless cockpit that would increase pilots' field of view
What I am suggesting is a hybrid windowed/windowless cockpit. Of course your operating manual will have to cover failure modes and all that.

Steam Gauge instruments in digital format
The readability of need gauges has been discussed before. This display shows the traditional steam gauges in digital format, easier to read, but with the advantages of digital displays.

I find it much easier to quickly sight the needle pointer, easier than some of the other more common EFIS. Not sure if everyone thinks so.

A couple of observations about ASI styles (reference post #31):
The 'steam boiler' style gauge can give a quick estimate of speed based on position around the dial. Whatever you are used to, (automotive with zero on the left or aircraft with zero at 12 or 1 o'clock) a quick glance at the pointer position gives you an idea where you are at. Speed tapes(bottom) and odometer style mach readouts (middle) require reading and interpreting a numeric value.
One question: In the top figure (2.7.1), how do you interpret Mach number? I assume the Mach dial rotates to compensate for OAT and places the current Mach next to the corresponding IAS. The single pointer would then indicate both Knots IAS and Mach. Correct?

For your point about car speedos starting at the left and working around clockwise - the old ASIs, I only know they were in older Pipers, had the same thing.
Mind you, the gauges themselves were everywhere with a drum type compass.
There may be a reason as to why it changed from that to a uniform, zero up the top - rotate clockwise ASI.
With anything, if you actually use it for long enough it becomes the way it should.

The screen is a transparent window, since these are transparent LCDs.
However, in IFR conditions, when all you see outside is white or black or grey for that matter, the LCD 'window' will be switched on, and it will display:

Yes, that's correct.

That Aeroglass looks fascinating.
More in line with the discussion title- suppose a company comes up with an instrument that is very easy to read, like modern car instruments - it has to go through certification, and that will add to its cost? Better keep the older one? Not sure how certification costs add up.

Paper : The Development of Automobile Speedometers on Car Speedometers
This paper discusses car speedometers throughout the years.
http://epublications.bond.edu.au/cgi...ntext=hss_pubs
Two interesting points :
1. There were some speedometers with zero at top right as in the 'modern' ASI
(Page 10, 1928 Mercedes-Benz 540 k)
2. This design is said to be counter-intuitive since increase in speed results in 'downward' movement of the pointer
(Page 23 3rd Paragraph)
