Has anyone used a GPS system as a passenger on a plane , how did it work?

Allways wondered if its possible to use a Satnav system as a passenger on a plane. It wouldnt work if the satnav measured barometric pressure due to the cabin being pressurised, but could you still get a signal onboard , thus giving you position , altitude and speed information?|||The above posts are full of it!!!


I use my Garmin GPS 196 OFTEN on commercial flights.


The gps is not a transmitter just a reciever!


THe gps will give altitude, airspeed from info from the satellites


As a courtesy, ask for the capt's permission. I have NEVER been denied.


As far as signal is concerned, never a problem while sitting in window seat.


Some will ask that you turn it off during takeofff and landing..|||If you can get a good signal it will work. You'll need to be in a window seat and will need to place the antenna in the window to get any signal at all. You may have to tweak the position of the antenna to get enough usable signals.





The altitidue is not calculated by barometric pressure by the way, but is calculated by the GPS if you have a strong enough signal from enough satellites. If you can get 4 or more satellites registered on your GPS, it will give you position, speed and altitude based on the GPS calculations.





Keep in mind that most airlines don't allow you to use any radio receiving or transmitting equipment in flight. That includes GPS receivers. I've done it several times on my company's corporate jets; the pilots don't care if we use cell phones or GPS receivers in flight. My GPS still shows the max speed of 660 MPH that I measured on one flight a couple of years ago. Pretty cool!|||you are not aloud to use on plane like you are not to use mobile phones sorry to tell you that,|||I fly American and their book says no GPS systems allowed by passengers|||it always worked! usually during cruise flight. the attendants will be most willing to help u with that. all u need to do is to find what u really like and u just call the attendant. they'll come to zap your visa after that. u'll find it convinent to use it in the plane, the Goods Payable Service.|||i have. several times and it works well as long as you are on a window seat and you have a map if your gps requires one. also some models of gps have a maximum speed because they were built for use in cars. if this is the case then you won't have speed information. lastly, contrary to one of the answers, you can also get a signal through the cockpit window although the signal is much weaker. i've tried it several times.|||You will only pick up satellites on the horizon that are in view of the antenna element. Also, speed is inaccurate when measured with a GPS. It will be close, but it won't be spot on.|||offcourse you can get the signal, why couldn't you?


It doesn't know if whether you are a passenger or a pilot.|||I used my Garmin E-Trex on a United flight between LAX and SFO and It worked great. I had readouts of altitude, speed and course.|||Never tryed a sat nav road type, but a normal GPS works fine. Never fly without one.|||I tried mine on two long haul aircraft recently and I couldn't get a signal, but I was mid row seating.|||Theoretically you can but I didn't have much luck. I couldn't lock


on to enough satellites to give me useful information (except


maybe 2% of the time. Pressurization wont affect the exercise


at all.|||It never ate the peanuts? maybe they were too salty.|||yeh i tried that than the pilot nicked it because he was a bit lost|||The signal is too weak to penetrate metal/concrete. Even the Pilot's windscreen has metal heating elements that prevent the signal getting through. So, no it wont work.
