If any airline or pilot allows the use of GPS, then why don't they allow the use of FM or AM
radios, shortwave radios, TV's or anything else with a local oscillator?

Personally, banning receivers might be a little too much on the careful side, but I would certainly
be upset if any one thought they could use a tranmitter, such as a cell phone.

I do wish that the FAA would change the official 'verbage' from "put away your cell phone"
to something like "make sure it is powered down and fully turned off", or "turn it off so that
the display is balnk". I'm sure a lot of non-technical travellers think it is OK as long as
they are not actually talking into the thing.

It looks like GPS has temporarily 'fallen into a crack' and forgotten by some airlines, but
as some posters have mentioned, airlines are including them in their prohibited from use list.
