From: "Bill Heron" <wheron@xxxxxxxxxxx> Sent: Monday, December 22, 2003 5:27 PM I've been having a great time with the GPS device which attaches to my Palm pilot, very helpful when driving in unfamilar areas. My question is: would it work in flight (in other words, would it be likely it could pick up satellite signals from inside the passenger cabin) and is it a "permitted" device? Wouldn't it be great to know exactly what town you are passing over on a long flight? I answer: I've used GPS in flight for many years. I used to ask the captain if it was ok, and got a positive response most of the time, although I had a few rejections. Lately I've given up asking, and when an FA asks "is that a GPS" I say yes but it's off until the electronic stuff (computers etc) are allowed. You will need a window seat, and if the GPS is not the most sensitive you will probably need the antenna to be up to the window. Initialization is often difficult, so I try to get a fix at the airport before boarding the plane to let the gadget know roughly where we are. The one I have now records time and date with the waypoint, so if I am taking a picture I usually mark a waypoint so I will be able to get an idea of what I am photographing.
