Thanks Ian and Mike.
That advice is a bit more than a hint! Now why didn't I work that out for myself? On reflection - DON'T ASK! Will make the mod soonest. Why is this sort of thing not incorporated as standard, by the glider manufacturers? The Principals almost invariably live in a climate vastly different to that experienced in Australia, but in reality that is no excuse, as I am sure that they get lots of feedback from their customers here and from others based all over the world: Extreme hot and extreme cold. Maybe all experienced in a single wave flight, over a few hours? I suspect that the glider manufacturers sometimes have quite a different agenda to their customers. In particular, think about the history of GRP glider finishes and the materials used. Comments?

Subject: Re: [Aus-soaring] iPhone I totally agree with Mike Borgelt on this one and URGE ALL to cut your holes to let the very hot air escape I know it can get to 75 deg C or higher there. So use a canopy cover when on the ground AND cut a hole or slot in the panel cover so the hot air can escape. You can put black insect screen mesh in the hole if you want. It is so important to let out that heat and can kill or at least interfere electronics. PLEASE CUT YOUR HOLES NOW!!!

Doesn't seem to stop people using iPads for Oz Runways in power planes. Glider cockpits in summer get MUCH hotter than that which brings me to this advice: Your electronics will last longer if you keep them cooler. The rule of thumb is that each additional 10 deg C halves the mean time before failure. Now take a look at your glider instrument panel. As designed it is a perfect solar oven. Perspex above with a black cover over the instruments, nicely curved so the hot air can build up under the cover with no ventilation. I know it can get to 75 deg C or higher there. So use a canopy cover when on the ground AND cut a hole or slot in the panel cover so the hot air can escape. You can put black insect screen mesh in the hole if you want.

I dont know what the temperature was inside the cockpit, maybe minus 10, but nothing too extreme. but it gave up pretty quickly. All other loggers, pna's, instruments, oximeters etc were fine but the iphone gave up too easy. Shame because i hoped it might serve as a second backup gps. Not too sure how well it would go in the heat either. It seems too clever to put up with that.

However, the maximum operation temperature is listed as 35 degrees. It's likely that the inside of our cockpits exceed that on some days. An app like See you flight recorder does not need to be in sunlight but can be in a pocket, which could reduce it's temperature (depending on how excited you are!). Does anyone have experience of using an iPhone in their glider?
