Sunlight readable PNAs reviewed
There is an interesting discussion here at
http://www.postfrontal.com/forum/top...89&whichpage=6 with a lot of pictures I have taken out of new PNAs with 800-900 nits displays. This PNA has also a spare RS232. I am searching for a Dell Streak to compare, but it is was gone out of production a few months ago. With the sun in front of us, and not in the back, brightness is the only help to make the screen visible at all. I am also about to review the Holux 61CS, which is a long awaited unbranded device with a very good visibility. (I dont sell them!) paolo |

Brightness minimually affects the sunlight readability. Contrast ratio is the most important factor. The Craggy Aero Ultimate Le aviation quality display sets the standard in sunlight readability it delivers a radically high level of screen brightness that results in unparalleled picture sharpness and vividness. The VHB LED backlight in the LCD module consumes only 4.5 Watts at full brightness. The LCD screen temperature is quite small and there are few thermal management issues. The LCD module displays a VGA (640 x 480) image. Contrast ratio is the most important factor in high and full sunlight applications. Contrast ratio of a display is defined as the luminance (brightness) ratio between a brighter state and a darker state. The color LCDs “white” state and “black” state are used to calculate the contrast ratio. Contrast ratio = CR = luminance of the “white” /luminance of the “black”. If white and black are equally bright, then CR = 1 and the display is not readable. Due to the coatings applied to the display the contrast ratio of the Ultimate Le is extremely high. The high contrast ratio makes the view in direct sunlight only slightly dependent on the backlight intensity. Even at the low backlight setting the display is totally readable in full sunlight. These characteristic contribute to the overall superior direct sunlight performance in the cockpit. No longer do you need to run software in the white or no terrain mode, the color and clarity are vibrant in full sun. http://www.craggyaero.com/ultimate_le.htm Richard www.craggyaero.com |

Sunlight readable PNAs reviewed
Gentlemen, the sunlight readable screen I (and many people out here) want to
buy should not be expensive! A 500 euro device is too much, and way too much a 1000 euro. These should be portable devices. A great deal of people is buying cheap but usable PNAs such as the MIO400 (60 euro, new not refurbished), with serial port and internal gps. The devices we mention on the forum share the same price range: the 900 nits one, 5 inches 800x480 with serial port is sold in the UK for 275 euro. Most people want a device sized between 4 and 6 inches. We all know that 7 inches and more becomes a big problem to be installed aboard. This is why most of PNAs are sized 4.3 and 5 inches. Bigger LCD will not fit easily (and costly) rack mounted. Manufacturers are improving LCD coating process, brightness and contrast ratio, to provide cheap devices. Of course if you want and can spend more, LX 9000, Craggy Aero Ultimate, Triadis, there are several great choices! heppy 2012 everybody paolo "John Galloway" ha scritto nel messaggio .com...

John Galloway having flown last year with a LXminimap and the connected vario, I think people are missing a large safety and convenience issue by concentrating on sunlight visibility and not the total user interface. The eyes-in-the-cockpit time required to use a touchscreen to move between maps and pages, scroll through turnpoints, select a new turnpoint, and return to the original screen is several to 20 times longer than when using a well set up stick controller or other remote control device. The operation described can be accomplished with a single button press and a glance with the LX stick controller. In my mind this is as important as sunlight visibility. |

My thoughts on the Streak with XCSoar is - moving through various pages or screens with XCSoar requires a finger swipe to the left or right depending on what screen you are looking for -there are eight that can, when once set up, be accessed easily with swipes. Selecting a new turn point on the fly is as simple as touching the turn point location on the moving map, and acknowledging it when the turn point info window comes up on the screen, by pressing "GoTo". Takes a couple of seconds. Making a new contest task from scratch, on the fly, is a bit of a chore though, and probably is with any soaring program. Changing a task from the task file takes about 15 seconds. Mike |

Changing a task from the task file takes about 15 seconds. Mike I use XCSoar with a Droid phone and a bluetooth GPS (45 USD). I rent and don't own a ship. XCSoar switches modes automatically. So you can design your own set of data fields (infoboxes) for cruise, thermal and final glide. So you seldom need to swipe. It even has auto MC, so you don't have to fiddle with MC. Use it in sim mode, or with Condor on the ground to get proficient and this greatly reduces fidget time in the cockpit. The team at XCSoar has really brought this app a long way and it's still being imporved at a fast pace. I personally think it it very hard to evaluate these screens by tossing them out in the sunlight and firing off a photo. In reality most screens that do well in sunlight, do so not by the strength of their backlight, (backlight can rarely compete with full sun) but by there ability to "glow" and actually take advantage of direct sun. Some of the old iPaqs do this, but there is a specific angle to the sun that makes them glow brighter. Having these devices on a mount with the ability to swivel them around really helps their readability. Then some devices are not helped by sunlight and are better shaded somehow. Fly under the shade of a cloud, and the whole problem changes. Backlighting becomes a bigger factor. To complicate it more, some devices like Oudie have a matt glass screen, where others have glossy. The glossy reflects objects that can make the screen hard to read, but they can also be angled toward dark objects (like the black t-shirt I wear) which really makes the screen pop. Matt screens don't have the annoying reflections, but they scatter light and have a low contrast hazy look to them. Maybe better placed in shade or hooded somehow. The exception seems to be paying a lot of money for a navigator. A Garmin 369 or 496 has very powerful backlighting. ... akiley |
