iPad Air with JeppFD in the CRJ-200 with heated windows works fine with an external antenna.

Have not got it to work with the internal antenna.

Tested the iPad Air and Foreflight in the Archer and had no reception issues. Worked like a champ on Friday too sitting in the FBO all afternoon watching the T-storms and 25 kt cross winds roll through before I decided to go drink beer instead.

While you can buy the wifi only iPad and save some cash, you'll spend the money you saved on an external bluetooth antenna. In a light GA A/C, there generally is no need for an external antenna, since there are so many windows on your typical GA.

I like having the cell plan personally, because I can pull weather information, etc. from the internet real time when I have coverage. Over here in Hawaii, I get a signal about 70% of the time in between islands.

Additionally, not only does the iPad chip pick up GPS, it picks up GLONASS as well, which is the Russian constellation--so you have some additional redundacy, even though you don't have RAIM.

You have to get an external USB battery off Amazon, or hopefully your A/C has a cigarette lighter adapter!

Did you buy the "Pro" version that supposedly superimposes your position over an approach plate?
