iPad (3rd gen) mount - Cessna 172

[CruiseAttitude]

Hi again everyone,

After playing with the iPad 3 at my local Apple store I decided to take one home. I've installed SkyDemon on it, I had been using this on a Windows PDA up until now.

I understand that the 'airplane mode' disables the GPS, however would just disabling mobile data (under settings) turn off the GSM radio and still allow the GPS to function?

I've just tried this and SkyDemon maintained a position fix, I made sure wifi was also off as I know that can also be used by the iPad for location information. I might be missing something here though.

NB: When mobile data is disabled, where the network operator name usually appears in the top left is replaced with 'iPad'. So I imagine that it is not connected to the network at all.

Thanks

Ps, thanks for the recommendations of the RAM mounts, I will have a look.
