Ever felt the urge to carry a GPS unit on a plane? Would a GPS work inside the plane? What would it be like truing it thousands of feet in the air?

A GPS is considered pretty safe for use inside a plane. You will find that some airliners allow their usage but it's better to check their terms and conditions. You will even have to check whether the it's allowed on the flight you are boarding. In case of doubt always ask and be informed to avoid confrontation with the law. Make sure you follow the instructions laid by the airlines, no matter how strongly you believe that it's safe to use a GPS on the flight.

You have to get a clear signal from the satellites if you happen to carry one such device on n allowed flight. Window seats are the best option in this case.

Hand held or in car GPS devices are not build to be as accurate as the navigation system of an airplane. The personal GPS unit could lack accuracy or fail to provide your location or speed during the flight.

As mobile phones are generally not allowed on most airlines, you will be out of luck if you want to use your mobile GPS feature. Turn off any voice commands specially if you have downloaded and installed any alternative funny GPS voices to avoid keeping you co-passengers from giggling.
