July 10, 200223 yr I've seen a professional ifr-mcc simulator.It uses a plane screen, but the projector is placed on the top of the cabin (approx 2,5m maybe 3m height) and the cone is oriented toward the pavement.As to say the projector fires at approx 45
July 14, 200223 yr I cannot help much either, but I have purchased a Sony VW10 which has 16:9 but as you say getting it wide enough from close range is a problem. I am looking at rear projection so that I can put the screen very close to the front windscreen.Chhers.............Brian
July 15, 200223 yr I'm still in the planning stages with my cockpit so I'm hesitant to give unqualified advise, however I can pass on my thoughts re: visuals so far. >>I will use a projector (1024 x 768 ) to project from the rear to avoid the problem you descibed with trapezoidal appearance (known as keystoning). Some LCD projectors have a feature that makes corrections for this effect however I believe that it is at the expense of some resolution/ output quality, and I'm not sure how well it corrects this, should you want to mount it above your cockpit. I also have limited space for my project so rear projection is impossible but desireable because you can get the screen nice and close. So what's the solution? >>I intend to mount the projector towards the rear of the cockpit roof, and fire it towards a mirror straight ahead (angled 45 deg down) which reflects to another mirror mounted behind the screen at 45 deg. On paper it looks like it should work, however I'm not sure about the final outcome until I try this at a later date. I'm not sure about what projector to buy, and making a LCD projector is also an option at 1/3 the cost , which means I can have 3 projectors running :) . Go here for more info on this ( http://www.diyaudio.com/forums/showthread....light=simulator )There are lots of guys trying different methods so it's all new . That's about as far as I know about visuals.If you find some good info let us know.Cheers,Nick
July 15, 200223 yr Can anyone tel me how backprojection works? Do you use a special lense for this? I assume left and right has to be inverted for this.Or is this a function that is contained in the projector?Thanks for any answerNorbert Bosch EHAM
July 16, 200223 yr Norbert,Rear projection for a flightdeck is similar to what is used in a rear projection televisions. The only change is the light output method and screen type. Rear projection TVs use three CRTs. One red, one blue, and one green. The light from the CRTs is bounced off a mirror and on to the back of a plastic lenticular screen. Rear projection, using an LCD projector, uses a high intensity bulb and colored liquid crystal displays. Light from the projector is shown on the back side of a special fabric screen, but large lenticular screens are also available at a cost. The big expense is when you don't have enough room behind the screen to get the image as large as you need it. In that case, a set of specially cut mirrors is needed to bounce the image onto the screen.Most projectors do have a zoom feature. Optical and digital. Optical is best and just changes the optics in the lense. Digital does it electronicly, but the image can be very pixalated. Most projectors also have a feature in the setup menu where you can reverse the image for rear projection. The image can also be turned upside down for different mounting situations. One important note. In another post in this forum, it was pointed out that a projector capable of 1024 x 768 native resolution is far superior to an 800 x 600 one. But with the increase in resolution comes cost. About $1,000.00 more for a 1024 x 768 projector.This web site will help: http://www.da-lite.comRichard
