I disagree that the older (3800 and before) screens were easier to read outside. I think the 3900 and later a slightly better. I suspect the preference is affected by quality of eyesight and age. The biggest problem I have is getting enough contrast to be able to focus properly, whether at my desk or in the cockpit. The 39xx has better color rendition indoors and out, but for me, the 38xx has better contrast under sunlight. The backlight of the 39xx isn't quite bright enough to overcome the ambient light levels and glare. To make either one usable in flight, I have to do without terrain, use the largest fonts available, and use a very contrasty (essentially black and white) color scheme. Marc |

I think the 3900 and later a slightly better. | Paul Remde I think then on balance we can say that the H3950 is the best model for gliding at this stage and that HP would do us all a favour by improving their displays for outside use. Perhaps a slider could be offered to the user that adjusts the contrast at the expense of colour accuracy? Perhaps this could be automatically changed by an "ambient light brightness" sensor! (perhaps the infrared receiver can do this now?). It is not just glider pilots that care. Pocket-PCs are great for in-car-voice-guided-navigation systems, too, as well as for general use outdoors. HP also need to keep the display size large and fix the inadequate audio volume to have a chance at this market. Cheers, Jim Kelly. |

Marc Strange, I have been using a 2120 running Glide Navigator II (good program, possibly clearer graphics than Win-Pilot and a lot less colour). I bought an iPaq 5550 to improve the display, and in daylight in the cockpit it is absolutely no better than the 2120. Ten times the price, though. Mike |
