Joe, Southwest Airlines is the only airline I am aware of that explicitly permits GPS according to their in flight magazine. Most other airlines either ban GPS use or don't mention it. Our recommended policy is to ask the pilot for permission. Don't ask the flight attendant. You do this by writing a print note on the back of a Braille card saying, "may I use my Braille GPS?" Ask the flight attendant to present this to the pilot. I have rarely turned down. I have noticed recently that some airlines mention Bluetooth as a forbidden technology. I think the GPS is in a bit of a gray area. It is not like a cell phone but it isn't quite a DVD player either although it does not transmit other than the Bluetooth signal which goes up to 30 feet. As I say, ask the pilot unless you are on Southwest. Mike >Hello to All, > >I know that folks on this list have used GPS while flying on commercial >aircraft.
