The most frequent reason for not allowing cell phones, GPSs, etc, is supposedly because aircraft have limited RF interference shielding for the electronics, the cockpit GPS units being one of those systems they want to avoid inteference affecting. However, this seems more silly all the time. Some airlines are performing trial runs of wireless ethernet, plus PDAs with a built in cell phone (or is it the other way around? ;)) are not banned by the FAA. http://news.com.com/2100-1034_3-1010231.html Andy -----Original Message----- From: az-geocaching-admin@listserv.azgeocaching.com [mailto:az-geocaching-admin@listserv.azgeocaching.com]On Behalf Of RopingThe Wind Sent: Friday, May 30, 2003 2:56 PM To: listserv@azgeocaching.com Subject: Re: [Az-Geocaching] GPS on Commercial Airliner? >From: "Teryr Hernlund - [General Bracket]" >Reply-To: listserv@azgeocaching.com >To: >Subject: Re: [Az-Geocaching] GPS on Commercial Airliner? >Date: Fri, 30 May 2003 12:03:19 -0700 > >In any event, depending on the airline (America West has a strict policy >against GPSr's), just pack it in >your carry-on like the rest of your >stuff.

I fly hot air balloons (FAA certified aircraft) and I always use GPS on board. An interesting note I thought yall might be interested in: I use two way radio communication with my ground crew. The radios are Motorola VHF radios. When my radio is turned on, I lose GPS sattelite reception. This has happened with all my GPS's.. my Magellan 300, my Garmin 3+ and my Garmin Etrex Legend. So, when I am flying in competitions where my GPS is being used constantly, I cannot have my radio on and talk to my ground crew as my GPS will stop tracking! I havent really tried changing frequencies in my radio's to see if that would fix the problem. But, have been wanting to try that (my crew if good and I rarely have to talk to them anyways except when getting ready to land). On the other hand, my aircraft radio (ICOM IC-A22), which operates on higher frequencies, has no effect on my GPS. Interesting! On the flip side of the coin.. my GPS's have no effect on the radio's or any other instruments at all.
