My friend has a large golf dome and he is starting to get into renting it out for other sports activities such as soccer, flag football, and kickball. I showed up last night to help him take some aerial photos from inside the dome, and the Phantom wouldn't take off (full gps signal inside dome) I was trying to launch during a kickball game and the phantom wouldn't leave the ground. It didn't hit me until I was on my way home, that I was about 500' from a Category B airport. Anyway, is there a way to bypass this? If I gps lock at my house, power it down, unplug the GPS, and fire it up at the Dome, will I be able to fly in ATTI? Thanks for your help.
