Just turn off all connections via Manage Connections before powering down your BB before takeoff. When you power it back on the connections will still be off as required by the airline/FAA.

It requires signal from the GPS satellites. However, the GPS receiver in the BB is just a receiver. It does not transmit back to the satellites. GPS users have no control over the signals transmitted by the GPS satellites.
Assuming you could get line of sight to enough satellites you would get positioning data. However, most GPS apps require a data connection for mapping.
