SUPPORT CENTER: USING WAYPOINT ON A AIRPLANE

It can be fun using your GPS on a commercial flight. This is permitted on some airlines above 10,000 feet and prohibited on others. Check with the pilot or airline to be sure. GPS reception is limited to the data that can be received via the windows. It is possible to get signals via multiple windows but not likely so get a window seat. To be successful follow these tips:

* Get a fix on the ground within 30-45 minutes prior to the flight with as many satellites as possible.
* Try to arrange your window seat to be on the south side of the plan in the northern hemisphere.
* If your GPS permits it preset the altitude to 15,000 feet or so.
* Use an external antenna wedged between the window shade and the window pointing out.
* otherwise, place the antenna as close to the window as possible.
* Be patient, study the status page for reception data and aim the antenna to improve reception.
* Do not use any sort of battery save mode.
* When successful you will be able to determine ground speed for the plane, real altitude and direction, and show location on a map. You may be able to see distance to destination depending on the mapping software.
* After using it in a plane the GPS may need a little longer to get a fix the first time at your destination.
