Your GPS is essentially measuring the "groundspeed". If you had a 100 mph tailwind, and the 737's airspeed was 537 mph, then your GPS would register a groundspeed of about 637 mph.

The signal wasn't great. I too have Microsoft Streets and Trips with GPS, and I too placed the receiver on the window and it worked some of the time. Other times I had a hard time getting a signal. 550 miles and hour at 40,000 feet. I Thought this was strange because I looked at the specs on a 737, the only thing southwest flies, and for a 737-700 (the version we were on) the max speed was .82 Mach. this is only 537 MPH. (I'm not an aerospace junky)It was intersting, and no one asked any questions. The onboard magazine from the airline listed GPS receivers as an approved device. The other intersting thing is that you can see what city you are over or what state you're over at any given moment. I recommend bringing your device and the biggest battery you can (I ran out in my laptop), and if they say "no", they say "No," and you comply. I just used GPS on a Southwest flight last night.

After 9/11 I always ask the flight crew AND talk with my seat mates. GPS use seems to be arbitrary between the airlines, but the captain on the flight always rules. Discussing GPS use with the passangers puts their minds at ease and often generates discussion and interest. I've found that by putting the GPS unit in my shirt pocket and sitting by a window (either side of the window) has worked well 99% of the time.

I don't blame you. Ever since 9/11, and to some degree prior, such harmless activity has been construed to have an evil purpose. I'm a photographer and I am routinely hassled by police, guards, etc. when I take pictures IN PUBLIC and on public property. Alas, this trend will never reverse. johnson said, I was very PO’ed…

If they want it turned off, you must turn it off. That falls under the “federal regulations require that you comply with all crew-member instructions” category.

I stuck the receiver to the window just like Dave G above. It worked great. The stewardess asked me what I was doing and I told her I was using GPS. She was very interested and asked me how fast we were going. I said 478 mph at 21,000 feet. She came back a few minutes later and said the Captain said that was correct!!!!! She was young (25-ish) and she was very into the technology. The next leg was different. The stewardess asked me what I was doing, I answered GPS and she was very upset and said turn it off. So I unhooked the GPS receiver and was only using the map feature. I wat GPSas going to track our route "manually." The stewardess walked by 2 minutes later and rudely reminded to turn off that GPS. I said I had disabled the GPS and she stormed off. She came back 2 minutes later and said the pilot had asked me to turn the computer off entirely because they copuld not be sure that I had actually disabled the GPS. I was very PO'ed...

GPS Review Fri, 06 Oct 2006 20:38:19 +0000 http://www.gpsreview.net/10-myths-about-gps/#comment-7419 [...] Quite a few people have been asking us questions or making statements that leads us to believe there are some misconceptions out there about how GPS devices calculate routes, and what part of the process is responsible when an obviously bad route is being suggested by your GPS. Perhaps this should be appended to our 10 GPS Myths post. Let’s dig into this a little bit and figure out where the map data provider, the GPS device, and the GPS software play a role in calculating routes.
