REFLECTOR: IPad

[Dave Philipsen]

Hmmm....I have not found that to be true in my case. Are you sure that your iPad is in "airplane mode" with only the wifi turned on? ForeFlight does not determine my location when I do that.

You'll find that ForeFlight will not attempt to display your location but Google Maps *will*.  I suppose that this is because Google Maps is content to use the rougher approximation of wi-fi only whereas the ForeFlight programmers decided to only utilize the most accurate method.

You'll find that ForeFlight will be perfectly fine in that situation.  And, it's probably the best way to use ForeFlight while you're flying. There will be less drain on the battery if that concerns you since both the cell radio and the wi-fi radio are turned off leaving the GPS turned on.

The best way to solve that mystery would be to take your iPad flying, crank up Foreflight, and see if you get a moving map with your airplane symbol, GND speed readout, ect. . I've been using Foreflight for about 3years with my iPad (3G) and I know that if I have the unit in "airplane mode" (cell towers off), Foreflight will not work even if I have WIFI turned on. The same switch that controls cell tower operation (the airplane mode switch) also turns on and off the internal GPS unit. fWIW
