I am going out to AZ soon from IL, if I programmed my car’s GPS with just the destination of AZ, what would happen. Any idea on what would happen if I tried this out? And please, no “you’ll get kicked out of the plane” and related answers, seriously….I want serious answers.

    i guess it will still work
    idk

    well a plane wouldnt find out if you had one.
    a GPS will do what a normally does.
    keeps track.

    well here a serious answer, what?? second why would you want to fly with a GPS these are questions for a question why would you program the GPS to just AZ

    Rather a waste of time I suspect. GPS requires a clear view of the sky in order to pick up the radio signals from the satellites; if you are sitting in the back of a commercial aircraft then that won’t be possible. If you are in a light aircraft and can position the device on the coaming then it should receive signals. However, a car GPS is preprogrammed with road information not airways – so still not a lot of use. There are specialised GPS devices for aircraft can you borrow or hire one?

    your not going to hurt anything but legally you can not have anything on unless it is approved if you type in flight aware and your flight number you can see the route in which you are going to fly but gps in a big aluminum tube dont think its going to work the planes have 2 antennas for the gps you will not

    If it would pick up signals you would want to just view map and not program a destination. If you put in a destination it would drive everyone crazy with it calling out “recalculating” Or whatever yours says.
    Also, in map mode it will display the speed that you are going. Most likely though, you would not be able to get signal.

    You’d be committing a federal offence if you did that.
    That means you’d get the FBI after you if anyone found out.
    You don’t want that.

    Most auto GPSs won’t handle the speed, I’m not sure why but they just can’t keep up I guess.

    You’ll also have trouble getting a signal from most places in the passenger compartment, and the crew will ask you to shut it down if they see it. GPSs are passive, no emissions, so they don’t upset the avionics.

    If you are in a window seat and can get the GPS close to the window then it will lock on and work. But if you program in the destination it will spend all its time getting upset with you for not taking turns and recalculating the route. Unless you can set it to off-road mode, which I can with one or other of my units.

    There is a FAR that allows operation of a GPS receiver in all modes of flight, or at least there was. I wouldn’t cross the crew by not switching it off because that would break other federal regs. I flew ORD to OAK once next to an off-duty pilot, he was interested to see the ground speed and altitude that my Garmin GPS V was reporting, we rose all the way as the pressure changed. He wasn’t the slightest bit concerned.

    (I can’t help wondering if a little GPS unit wouldn’t have saved a couple of aircraft that lost their presure instruments. They could hold speed by power setting and attitude and then use the GPS for altitude and even navigation. Two Boeings in South America and maybe Air France 447)
