Using iPhone, iPad as a gps in jet
Hi
During long flight over Europe, in FL300, I have tried to use iPad and run GPS. Just to test it. What a surprise, that GPS did not worked (no matter if the device was in airplane mode or not). I jave tried the same with iPhone 4 but with same result. It happemed in cockpit of CJ2, and handheld garmon gpsmap, that I carry worked perfect.
Does anyone have a clue, why GPS does not work in this enviroment?
