I found this thread while looking for the same thing. Thanks for the Locus tip; I've installed it and it seems to be what I need. I'll test it out on a cross-country flight tomorrow. If not then I'll try MapDroyd next.
"Strictly spekaing, you are supposed to turn off your GPS receiver while on a commercial flight. "
Strictly speaking, that's NOT correct. Most airlines do quietly allow it, some do not (click for latest list). Sure, all airlines require that you turn it off during takeoff and landing, as with all electronics, but above 10,000 feet you are allowed to use it.
Alas, the cabin staff may not understand this or be aware of their airline's policy, so what I do is A) try to find a policy statement on the airline's website and print that out to show them just in case (politely), and B) use it discretely -- when they come by with the drink cart I tuck it away. No point in creating needless drama.
Edit: after posting this I realized I hadn't seen page 2 of this thread, and went back and scanned it. Now wishing I hadn't checked it at all. In short: yes, there are valid reasons for these policies, and the reasons don't all have to do with the actual RFI. Imagine, misinformation in an internet forum ...
