Hi There is of course a non technical, non EMC reason for such a ban. Security. It might be considered that exact position and speed information could be of use to a passenger with ill intent. Note that most airlines turn of the moving map on the descent. Robert G8RPI.

It is interesting that American is listed as banning them as of October 2009 (apparently they have switched back and forth on this policy)... Earlier this week the Mehaffy list had American as approving GPS, but I checked the AA website earlier this week and it listed them as being banned. I contacted Mehaffey and maybe he updated the list after contacting AA. I'm flying AA this coming Friday, so I'll see how it goes. I flew up on Delta and used my Garmin Legend HCx in a window seat and it worked beautifully. My next leg was on a United Shuttle, and despite their website saying GPS was approved, the flight attendant specifically announced that they were not approved. I didn't push it since it was a 0.5 hr commuter flight. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Col Keith E.
