Can you use the iPhone 6 as a screen only without getting a wireless line ?

I believe the one time I had to reinstall data files was due to an iOS update. And I belive the clearing of data from parameters and map data is from storage availability. I have too many apps and photos and sometimes forget about adding more photos.

It might sound completely crazy, but how about using a dedicated device in the glider?

I do. An iPhone 6 Plus.

Not sure what you are asking. Using iGlide and an iPhone 6 or 7, regular or plus, by itself, you will have a fully featured glider computer. It uses its internal GPS and barometer, and works pretty well. What you will not get is any variometer or Flarm data. You will get position and glide slope information, makable landing sites and arrival altitudes, terrain and airspace clearance, even the thermal assistant works (though not as well). You will not get instantaneous wind. The thermal assistant is not as accurate, nor does it have the wind vectors. No Flarm targets will be displayed. For those, you need the serial stream of data either from an Air Vario, or the Air serial-to-WiFi convertor hooked up to another variometer system capable of streaming LX style serial data. With a proper connection, it will synchronize the McReady setting between vario and iGlide, and all the GPS and barographic data will come from the vario.

You will also find you want to connect the iPhone to a charging cable, as it will only last 3 hours or a bit less on the internal battery.

When I say it works pretty well: One season I had some trouble with my WiFi stick in the Air Vario, so the iPhone would disconnect from the vario in flight. After a few seconds of no data, iGlide defaults to the iPhone internal sensors and keeps going. On several occasions I flew for long periods without having noticed the difference. When I noticed, it was due to the lack of Flarm and wind data. You can put up a navbox displaying the GPS source, which tells you right away - but you might not notice otherwise. There is very little difference in the GPS recorded fixes from the phone vs. the vario. The barograph in the phone is not quite as sensitive (and of course not total energy).
